Your Digestive System

Digestive System Outline:

Human digestive system
Discussion Questions If a sphincter or valve did not close completely, what would you expect the contents to do? Bile flows from the liver through the bile ducts and into the gall bladder for storage. The overall process of digestion and absorption of food occurs in this tube. The celiac artery is the first major branch from the abdominal aorta , and is the only major artery that nourishes the digestive organs. While hemorrhoids can cause some discomfort, they can typically be treated with over-the-counter ointments, creams, or suppositories. The bile is released in response to cholecystokinin CCK a peptide hormone released from the duodenum.

Q Using the numbers from the diagram above, list, in order, the structures each mouthful of food or drink passes through on its way through the digestive process. Using the numbers from the diagram above, list, in order, the structures each mouthful of food or drink passes through on its way through the digestive process. Make a Purse-string Sphincter or Valve.

In the digestive system, there are a number of places along the way that are designed to help regulate when, what direction, and how fast, food travels. For example- the cardiac sphincter separating the esophagus from the stomach; the pyloric sphincter between the stomach and the duodenum; the ileo-caecal valve between the small and large intestines; and your anus.

Baste large stitches around a rough circle of the material. Leave a long tail of thread at each end. Gently pull both ends to bunch up the fabric and make the circle smaller.

Alternatively, you could do the same with the open end of a sock. Either way, you are creating a pouch, or a dead-end most similar to that of the appendix. If the sock had the same closure at the toe end, then it could better represent a stomach or a very short bowel. The duodenum is largely responsible for continuing the process of breaking down food, with the jejunum and ileum being mainly responsible for the absorption of nutrients into the bloodstream.

Three organs play a pivotal role in helping the stomach and small intestine digest food:. Among other functions, the oblong pancreas secretes enzymes into the small intestine. These enzymes break down protein, fat, and carbohydrates from the food we eat. The liver has many functions, but two of its main functions within the digestive system are to make and secrete bile, and to cleanse and purify the blood coming from the small intestine containing the nutrients just absorbed.

The gallbladder is a pear-shaped reservoir that sits just under the liver and stores bile. Bile is made in the liver then if it needs to be stored travels to the gallbladder through a channel called the cystic duct.

During a meal, the gallbladder contracts, sending bile to the small intestine. Once the nutrients have been absorbed and the leftover liquid has passed through the small intestine, what is left of the food you ate is handed over to the large intestine, or colon.

The colon is a 5- to 6-foot-long muscular tube that connects the cecum the first part of the large intestine to the rectum the last part of the large intestine. It is made up of the cecum, the ascending right colon, the transverse across colon, the descending left colon, and the sigmoid colon so-called for its "S" shape; the Greek letter for S is called the sigma , which connects to the rectum.

Stool, or waste left over from the digestive process, is passed through the colon by means of peristalsis contractions , first in a liquid state and ultimately in solid form as the water is removed from the stool. A stool is stored in the sigmoid colon until a "mass movement" empties it into the rectum once or twice a day. It normally takes about 36 hours for stool to get through the colon. The stool itself is mostly food debris and bacteria. These bacteria perform several useful functions, such as synthesizing various vitamins , processing waste products and food particles, and protecting against harmful bacteria.

When the descending colon becomes full of stool, or feces, it empties its contents into the rectum to begin the process of elimination. The rectum Latin for "straight" is an 8-inch chamber that connects the colon to the anus. It is the rectum's job to receive stool from the colon, to let you know there is stool to be evacuated, and to hold the stool until evacuation happens. The end-product is expelled through the rectum and anus.

An unhealthy digestive system may be caused by: Chronic infections resulting from various organisms, bacteria, fungi, and viruses — An overgrowth of bacteria such as H. Food intolerances — Lactose and gluten intolerance can irritate the digestive system.

Over time, stress can cause serious damage to the digestive system, in the form of ulcers and hypochlorhydria. Heavy metal toxicity — Heavy metals such as mercury cannot be easily processed by the digestive system. Low hydrochloric acid HCl — A low output of HCl aka hypochlorhydria leads to bacterial and yeast overgrowth, which aggravates many chronic conditions.

There are many things you can do to support the healthy functioning of your digestive system: Fill your diet with nutrient-dense whole foods such as nuts and seeds. Increase your intake of saturated fats with extra virgin coconut oil. Add high-fiber ingredients such as flax meal to your diet. Increase foods that contain omega 3 fatty acids such as wild salmon and walnuts.

Avoid nutritional deficiencies by complementing nutrient-dense foods with quality supplementation. Supplement your diet with quality digestive enzymes. Increase your intake of probiotics to restore the balance of intestinal flora in your digestive system.
