Know Your Digestive and Immune System

The System functions:

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube in the body known as the alimentary canal or the gastrointestinal tract (GI tract). Accessory organs of the digestive system include the teeth, tongue, salivary glands, liver, gallbladder and pancreas.

Six major functions take place in the digestive system:

Ingestion – The intake of food through the mouth. The mouth and stomach are responsible for storing food while it is waiting to be digested.

Secretion – The digestive system secretes approximately 7 liters of fluid throughout the day. This includes saliva, mucus, hydrochloric acid, enzymes and bile which are used to moisten and breakdown food.

Mixing and Movement – This includes three main processes to move food through the digestive tract and increase absorption. They include swallowing, peristalsis and segmentation.

Digestion – Digestion is the process of turning large pieces of food into its chemical components. This begins with chewing food and is continued through the muscular mixing that takes place in the stomach and intestines.

Absorption – Absorption begins in the stomach with simple molecules like water and alcohol being absorbed directly into the bloodstream. Most absorption takes place in the walls of the small intestine.

Excretion – Finally, the excretion of waste removes indigestible substances from the body so that they don’t accumulate in the gut.

The immune system is the body’s defense system against viruses, bacteria and fungi. The immune system works to keep harmful agents out of the body and attack those that enter.
