Mouth/oral cavity begins mechanical digestion
- Salivary Amylase (AMS) - digests starch and glycogen
  - Parasympathetic Nervous System/PNS-ANS

- Nasal cavity is closed
- Epiglottis covers the larynx
Esophagus
- Esophageal Spincter
Stomach
- Cardia/Cardiac/Gastroesophageal Sphincter
  - Prevents regurgitation
- Pyloric Sphincter
Small Intestine - Biomolecule Absorption
- Duodenoum
- Illeum
- Jejunum
Large Intestine - Excretion and Water/Electrolyte Digestion
- Cecum
- Ascending colon
- Right hepatic fixture
