Digestive System

By: Adriana Uelman

Function of the system

All the organs work together to ensure proper digestion and absorption of nutrients.

Three Homeostatic problems that can occur

  • Jaundice:
Cause: excessive amounts of bile are absorbed into the blood stream because of a blockage resulting in a yellowish discoloration of the skin
Symptoms: Yellowing of the skin, pale stool, darkened urine, weight loss, flu like

Treatment: Anti viral medication

  • Diarrhea:
Cause: When the rate of digestion quickens the water and nutrients isn't absorbed

properly and becomes more of a liquid

Major Organs/ Functions

  • Mouth: entry of food
  • Pharynx: food passes through this to the esophagus
  • Esophagus: pushes food to the stomach
  • Stomach: mixes food with the muscles and gastric juices to break down food into chyme
  • Small Intestines: absorbs food and water, tiny villi grab nutrients
  • Large Intestines: bacteria absorb and break down food that has been missed
  • Liver and Gall Bladder: liver creates bile to break up fats and the gall bladder stores it
  • Pancreas: breaks down fats, proteins, and starch
