The Digestive System

Functions of the digestive system Ingestion Mechanical processing Digestion Secretion Absorption Excretion

Steps in Digestion Mouth – Crushing and grinding Stomach – Chemical Breakdown Small Intestine – Useful material extracted Colon – Water removal

Digestive Organ’s Functions Salivary Gland There are three main glands that deliver saliva to soften the food Epiglottis This is a trap door that covers the trachea to prevent food and fluids from draining into the lungs Esophagus This is a muscular tube that takes the food to the stomach. The contractions are called PERISTALSIS Stomach This is where the food goes and gets melted into a thick soup by the GASTIC ACIDS

It has three parts, duodenum, jejunum and ileum. Digestive Organ’s Functions cont. Small Intestine It has three parts, duodenum, jejunum and ileum. Duodenum Is responsible cor continuing to break down of food Jejunum Absorbing nutrients into the blood stream Iluem

The body’s sugar control board. Produces insulin and glucagon Digestive Organ’s Functions cont. Pancreas The body’s sugar control board. Produces insulin and glucagon Liver Food doesn’t pass through this organ, instead the liver secretes bile Gall Bladder Stores bile from the liver and releases bile into the duodenum Appendix We do not need our appendix, sometimes a piece of food gets stuck in here and causes an infection.

Part of the colon, used to store waste for disposal. Digestive Organ’s Functions cont. Large Intestine Also known as the colon. It has three major parts, ascending colon, transverse colon and descending colon. Rectum Part of the colon, used to store waste for disposal. Gall Bladder Stores bile from the liver and releases bile into the duodenum
