The Digestive System

The Digestive System

The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body.(You can scroll on text boxes)

The gallbladder stores and concentrates bile, and then releases it into the duodenum to help absorb and digest fats.

Its main function within the digestive system is to process the nutrients absorbed from the small intestine.

The pancreas secretes digestive enzymes into the duodenum, the first segment of the small intestine. These enzymes break down protein, fats, and carbohydrates.

The lining of the upper anus is specialized to detect rectal contents. It lets you know whether the contents are liquid, gas, or solid. The anus is surrounded by sphincter muscles that are important in allowing control of stool.

Food is pushed through the esophagus and into the stomach by means of a series of contractions called peristalsis.

You start chewing and breaking the food down into pieces small enough to be digested

The large intestine is a highly specialized organ that is responsible for processing waste so that emptying the bowels is easy and convenient.

The stomach secretes acid and powerful enzymes that continue the process of breaking the food down and changing it to a consistency of liquid or paste

The small intestine is the 'work horse' of digestion, as this is where most nutrients are absorbed. Peristalsis is also at work in this organ, moving food through and mixing it up with the digestive secretions from the pancreas and liver, including bile.

Heartburn or acid reflux symptoms include chronic cough and chest pain and burning. Knowing your triggers, such as certain foods, medications, obesity, or even stress, can help prevent heartburn. Heartburn treatment may include medications, home remedies, or diet changes.

Firstly, the food we eat is made up of many compounds made by other organisms which are not all suitable for human tissues and therefore these have to be broken down and reassembled so that our bodies can use them. Secondly, the food molecules have to be small enough to be absorbed by the villi in the intestine through diffusion, facilitated diffusion or active transport and so large food molecules need to be broken down into smaller ones for absorption to occur.

Ulcerative coloitis (UC) is type of inflammatory bowel disease that causes sores in the colon. Symptoms include abdominal pain and diarrhea, sometimes bloody. Treatment for UC may be a combination of over-the-counter anti-diarrhetics and prescription steroids or aminosalicylates.

Enzymes are needed because they break down the large food molecules into smaller ones so that these can eventually be absorbed
