It may also refer to the state of being healed, or cured or make healthy again. Physiological Homeostasis is the tendency of the body to maintain critical physiological parameters e. Health is feeling good and strong in the body and mind , and being free from disease or pain. Health is the level of functional and metabolic efficiency of a living organism. In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental, psychological and social changes with environment.
A state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity or weakness. Wellness - Healthcare Public Health is the science and art of preventing disease, prolonging life and promoting human health through organized efforts and informed choices of society, organizations, public and private, communities and individuals. Population Health has been defined as "the health outcomes of a group of individuals, including the distribution of such outcomes within the group".
It is an approach to health that aims to improve the health of an entire human population. The term adolescent and young people are often used interchangeably, as are the terms Adolescent Health and Youth Health. Young people's health is often complex and requires a comprehensive, biopsychosocial approach. Physical Therapy - Messages Fund Medical Treatments for People in Need Ethics in The Medical Industry customized care Palliative Care - Elderly Care Doctor - Physician Doctor or physician is a professional who practices medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease, injury, and other physical and mental impairments.
Physicians may focus their practice on certain disease categories, types of patients and methods of treatment—known as specialties—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice.
Medical practice properly requires both a detailed knowledge of the academic disciplines such as anatomy and physiology underlying diseases and their treatment—the science of medicine—and also a decent competence in its applied practice—the art or craft of medicine.
National Rural Health Association states that rural areas could be short 45, doctors by And other trade groups warn those numbers of unfilled positions could loom even larger. Since , more than 70 rural hospitals have closed. Nurse care giving Early Historical Doctors: A health professional may operate within all branches of health care, including medicine, surgery, dentistry, midwifery, pharmacy, psychology, nursing or allied health professions.
Errors made by Doctors Specialist in medicine is a branch of medical practice. After completing medical school, physicians or surgeons usually further their medical education in a specific specialty of medicine by completing a multiple year residency to become a medical specialist Medical Specialists webmd More Specialties Board Certification is the process by which a physician or other professional in the United States demonstrates a mastery of basic knowledge and skills through written, practical, or simulator-based testing.
Accreditation Medicine Categories wiki Medicine Categories wiki Medical Terminology is language used to precisely describe the human body including its components, processes, conditions affecting it, and procedures performed upon in. It is to be used in the field of medicine.
Notable aspects of medical terminology include the use of Latin terms and regular morphology, with the same suffixes and prefixes use quite consistently for a particular meaning. This regular morphology means that once reasonable number of morphemes are learned it becomes easy to understand very precise terms build up from these morphemes. A lot of medical language is anatomical terminology, concerning itself with the names of various parts of the body.
Medical Terms Definitions Doctor Exams Physical Examination is the process by which a medical professional investigates the body of a patient for signs of disease. It generally follows the taking of the medical history—an account of the symptoms as experienced by the patient. Together with the medical history, the physical examination aids in determining the correct diagnosis and devising the treatment plan. This data then becomes part of the medical record.
Examine is to consider in detail and subject to an analysis in order to discover essential features or meaning. Observe , check out, and look over carefully or inspect. Question thoroughly and closely.
Put to the test , as for its quality, or give experimental use to. Reference Range is the range of values for a physiologic measurement in healthy persons for example, the amount of creatinine in the blood, or the partial pressure of oxygen. It is a basis for comparison a frame of reference for a physician or other health professional to interpret a set of test results for a particular patient. Some important reference ranges in medicine are reference ranges for blood tests and reference ranges for urine tests.
Baseline Medical History is information gained by a physician by asking specific questions , either of the patient or of other people who know the person and can give suitable information in this case, it is sometimes called heteroanamnesis , with the aim of obtaining information useful in formulating a diagnosis and providing medical care to the patient. The medically relevant complaints reported by the patient or others familiar with the patient are referred to as symptoms, in contrast with clinical signs, which are ascertained by direct examination on the part of medical personnel.
Most health encounters will result in some form of history being taken Diagnostic Test or Medical Test is a kind of medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, and determine a course of treatment.
It is related to clinical chemistry and molecular diagnostics, and the procedures are typically performed in a medical laboratory. Vitals are body functions essential for life. Diagnosis is the identification of the nature and cause of a certain phenomenon. Medical Diagnosis is the process of determining which disease or condition explains a person's symptoms and signs.
Testing and Examinations - Software Testing Assessment Errors observation flaws Monitoring medicine is the observation of a disease, condition or one or several medical parameters over time. Transmitting data from a monitor to a distant monitoring station is known as telemetry or biotelemetry.
Bioinformatics are methods and software tools for understanding biological data. Body Burden Test Triage is the process of determining the priority of patients' treatments based on the severity of their condition. Endopat non-invasive assessment of Endothelial Dysfunction arterial health , is a functional test for early detection of underlying disease progression.
Problem solving is a skill that everyone should master. Biopsy is a medical test commonly performed by a surgeon, interventional radiologist, or an interventional cardiologist involving extraction of sample cells or tissues for examination to determine the presence or extent of a disease. Pathology is a significant component of the causal study of disease and a major field in modern medicine and diagnosis. Autopsy is a highly specialized surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause and manner of death and to evaluate any disease or injury that may be present.
It is usually performed by a specialized medical doctor called a pathologist. Also known as a post-mortem examination, obduction, necropsy, or autopsia cadaverum. Diagnostic Tests - Advanced Sensors Biomarker is a measurable indicator of the severity or presence of some disease state. More generally a biomarker is anything that can be used as an indicator of a particular disease state or some other physiological state of an organism.
Lab on a Chip is a device that integrates one or several laboratory functions on a single integrated circuit commonly called a "chip" of only millimeters to a few square centimeters to achieve automation and high-throughput screening. LOCs can handle extremely small fluid volumes down to less than pico liters.
LOCs may use microfluidics, the physics, manipulation and study of minute amounts of fluids. Jack Andraka video and text Body Parts on a Chip video and text Microfluidics deals with the behaviour, precise control and manipulation of fluids that are geometrically constrained to a small, typically sub-millimeter, scale. Lego Organ on a Chip is a multi-channel 3-D microfluidic cell culture chip that simulates the activities, mechanics and physiological response of entire organs and organ systems, a type of artificial organ.
The versatile use of exhaled volatile organic compounds in human health and disease. Exhaled breath contains thousands of volatile organic compounds VOCs of which the composition varies depending on health status. Various metabolic processes within the body produce volatile products that are released into the blood and will be passed on to the airway once the blood reaches the lungs. Consequently, measuring the total amount of VOCs in exhaled air, a kind of metabolomics also referred to as breathomics.
Scientists have found a potentially useful link between the presence of exhaled acinetobacter baumannii derived volatile organic compounds VOCs and patients diagnosed with bacterial pneumonia.
Lab Testing Facilities - Heart Diagnostics Flexible Electronics Capturing Brain Signals with Soft Electronics using long-term stable neural recording based on a novel elastic material composite, which is biocompatible and retains high electrical conductivity even when stretched to double its original length.
A team of engineers has developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios.
The biofuel cells generate 10 times more power per surface area than any existing wearable biofuel cells. The devices could be used to power a range of wearable devices. A new medical-diagnostic device made out of paper detects biomarkers and identifies diseases by performing electrochemical analyses -- powered only by the user's touch -- and reads out the color-coded test results, making it easy for non-experts to understand.
The top layer of the SPED is fabricated using untreated cellulose paper with patterned hydrophobic "domains" that define channels that wick up blood samples for testing. These "microfluidic channels" allow for accurate assays that change color to indicate specific testing results. A machine-vision diagnostic application also was created to automatically identify and quantify each of these "colorimetric" tests from a digital image of the SPED, perhaps taken with a cellphone, to provide fast diagnostic results to the user and to facilitate remote-expert consultation.
The bottom layer of the SPED is a " triboelectric generator ," or TEG, which generates the electric current necessary to run the diagnostic test simply by rubbing or pressing it. The researchers also designed an inexpensive handheld device called a potentiostat, which is easily plugged into the SPED to automate the diagnostic tests so that they can be performed by untrained users.
The SPEDs were used to detect biomarkers such as glucose, uric acid and L-lactate, ketones, and white blood cells, which indicate factors related to liver and kidney function, malnutrition and anemia. Future versions of the technology will contain several additional layers for more complex assays to detect diseases such as dengue fever, yellow fever, malaria, HIV and hepatitis.
Laboratory is a facility that provides controlled conditions in which scientific or technological research , experiments , and measurement may be performed. Medical Laboratory is a laboratory where tests are usually done on clinical specimens in order to obtain information about the health of a patient as pertaining to the diagnosis , treatment, and prevention of disease. Clinical laboratories are thus focused on applied science mainly on a production-like basis, as opposed to research laboratories that focus on basic science on an academic basis.
A synthetic, injectable hydrogel developed to deliver drugs and encourage tissue growth turns out to have therapeutic properties all its own. Food Sensors - Sensors ai Surgery Surgeon is a doctor who performs operations, which is a medical procedure involving an incision with instruments; performed to repair damage or arrest disease in a living body.
Incision is cutting of or into body tissues or organs. Surgeons may be physicians, podiatrists, dentists, or veterinarians. Surgery Encyclopedia Universal Anesthesia Machine Onebreath low-cost Ventilator Surgery Simulator Color Coded Surgery video Ultrasound Surgery video Web Robotic Surgery Invasive Surgical Procedure refers to surgical techniques that limit the size of incisions needed and so lessens wound healing time, associated pain and risk of infection.
An endovascular aneurysm repair as an example of minimally invasive surgery is much less invasive in that it involves much smaller incisions, than the corresponding open surgery procedure of open aortic surgery. A new type of implant scaffold to provide localised drug treatment and prevent infection. Battling bacterial infection with hexamethylene diisocyanate cross-linked and Cefaclor-loaded collagen scaffolds.
Organ Transplants Organ Transplantation is a medical procedure in which an organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ. The donor and recipient may be at the same location, or organs may be transported from a donor site to another location. Transplants that are recently performed between two subjects of the same species are called allografts. Allografts can either be from a living or cadaveric source. T-Cells Organ Donation is when a person allows to be removed, legally, either by consent while the donor is alive or after death with the assent of the next of kin.
Donation may be for research, or, more commonly healthy transplantable organs and tissues may be donated to be transplanted into another person. Some organs and tissues can be donated by living donors , such as a kidney or part of the liver, but most donations occur after the donor has died. As of August 1, , there are , people waiting for life-saving organ transplants in the US.
Of these, 96, await kidney transplants. Arteries flow into smaller arteries called arterioles, and then into capillaries. Capillaries are tiny blood vessels. The walls of your capillaries are so thin that things like oxygen, nutrients, and cell wastes can pass through them. The thin walls of the capillaries are what allow your circulatory system to make its deliveries!
For example, the blood that flows into your capillaries is mixed with oxygen. Your body cells need oxygen to do their jobs. Oxygen passes through the capillary walls and into your body cells. Get access risk-free for 30 days, just create an account. At the same time, carbon dioxide, which is a waste product given off by your cells, is picked up by your capillaries. You can think of the blood that gets picked up by your capillaries as dirty blood because it has lots of carbon dioxide and very little oxygen.
This blood is ready for a return trip to your heart. Blood vessels that carry blood back to your heart are called veins. Like arteries, veins come in different sizes. Venules are the smallest veins. They receive dirty blood from the capillaries. Venules drain into larger veins. If you look at the back of your hand, you'll see bluish lines. Those are veins that are carrying blood from your fingers back to your heart.
Your body has two big veins called the vena cava. They dump the dirty blood into the heart. The blood that returns to the heart needs to drop off carbon dioxide and pick up oxygen. Can you guess where your heart sends this blood to get clean? If you guessed the lungs, you're correct!
Oxygen-poor blood comes into the right side of your heart and gets pumped to your lungs. In your lungs, it drops off carbon dioxide and picks up oxygen. This new, oxygen-rich blood gets sent back to the left side of your heart. The left side of your heart pumps it out into the aorta for another trip through the body. Do you see how your blood goes in circles?
This circular pattern is why it's called the circulatory system! Your circulatory system delivers things like oxygen, nutrients, and cell wastes to different parts of your body. It's made up of your heart and blood vessels , which move the blood throughout the body in a circular pattern. To unlock this lesson you must be a Study.
