 The digestive process
Digestive Process-continued
Small intestine- About 22 ft long…unwound
• Most digestion takes place here
• All that remains is the water & waste
 Large Intestine- propels water (H2O) &
wastes to the rectum
• Water is absorbed & wastes are stored
Digestive Process-continued
 Kidneys- job is to eliminate waste or toxic materials from
the blood & maintain water balance in the body
 Liver- produces bile (yellow) which helps break down food.
• Very large in size
 Pancreas- produces pancreatic fluid which is vital in
digestion
• Also produces insulin which flows into the blood stream.
• Insulin- allows the body to use sugar & carbohydrates
