Overview of Anatomy and PhysiologyOverview of Anatomy and Physiology
• Digestive system Organs and their functions
• Mouth: Beginning of digestion
• Teeth: Bite, crush, and grind food
• Salivary glands: Secrete saliva
• Esophagus: Moves food from mouth to stomach
• Stomach: Churn and mix contents with gastric juices
• Small intestine: Most digestion occurs here
• Large intestine: Forms and expels feces
• Rectum: Expels feces
