Pathway of Food Mouth Large Intestine Small Intestine Esophagus Stomach Rectum Pancreas Gallbladder Liver
How does digestion start? Step 1 - Mouth Chewing breaks down food into smaller pieces. Enzymes in saliva help!
Step 2 Esophagus Peristalsis squeezes food from the throat to the stomach. Smooth muscles at work.
Step 3 Stomach Stores food and breaks it into tiny pieces. Mixes food with digestive juices.
Step 4 Liver Produces bile that helps break down fats.
Step 5 Gallbladder Stores bile made by the liver.
Step 6 Pancreas Produces enzymes to digest fats and proteins. Produces insulin Neutralizes acids that enter the small intestines.
Step 7 Small Intestine Nutrients from food pass into the bloodstream. Villi increase surface area to aid absorption.
Step 8 Large Intestine Absorb water from remaining food. Pass useless waste material from the body
Steps 9 & 10 Rectum and Anus 9. Rectum – Stores waste before defecation 10. Anus – Muscular ring that controls defecation

Functions of Excretory System 1. Waste removal 2. Maintain homeostasis of body fluids Inside your piggy!!
Organs of Urinary System Kidneys Urethra Urinary Bladder Ureters
Step 1 Kidneys Filter blood to remove waste and maintain homeostasis of body fluids
Step 2 Ureters Tubes connecting kidneys and urinary bladder
Step 3 Urinary Bladder Smooth muscle bag that stores urine
Step 4 Urethra Tube that carries urine out of the body
