Digestive System - Module 13 Flashcards
Digestive System
This system is responsible for digestion and absorption of nutrients, and excretion of waste products as feces
Digestive System
6 major organs of Digestive Tract
Mouth > Esophagus > Stomach > Small Intestine > Large Intestine > Anus
Histological Layer of Digestive System
