Function of the Stomach Within the Cardiovascular System

The stomach is a large organ located within the cardiovascular system between the esophagus and the small bowel. Its functions are storing and digesting food. When food enters the stomach, any bacteria are quickly killed by the highly acidic stomach environment, then the digestive process begins and the breakdown of carbohydrates, fats and proteins takes place.

Storage

• Food can be stored within the stomach for up to 4 hours, depending on how much food is consumed.

Digestion

• Using contractions and hydrochloric acid released by the stomach, the stomach breaks down foods, extracting vitamins and minerals and turning the rest into a pulp.

Secretion

• The pulp is then secreted by the stomach into the sphincter, and then excreted out via the bowels.

Flexible

• The stomach can grow and shrink to accommodate varying amounts of food.

Heartburn

• When stomach acids make their way up through the esophagus, heartburn occurs.
