The Digestive System
Related Medical Terminology • • • GI – Gastro-intestinal Colo- Colon Cheilo – lips Gastro – stomach Gingivo – gums -ia – condition Stomato – mouth Hepato – liver Procto – rectum - ‘itis – inflammation
The Basic Functions of the Digestive System • Digestion-the mechanical and chemical breakdown of food into a usable form • Absorption-the movement of molecules through the mucosal lining of the stomach and small intestine, and into the blood • Excretion-the removal of solid waste from the body • Sphincters-circular muscles that contract and move food through the GI tract.
The Digestive Organs • • • Mouth Pharynx Larynx Esophagus Stomach Small Intestines – 3 duodenum, jejunum, ileum • Large Intestines – 4 ascending, transverse, descending, sigmoid • Rectum • Anus
Mouth Digestion starts here!!! • Mechanical digestion-chewing or “mastication” • Chemical digestion-digestion of carbohydrates
Mouth
Pharynx • Also called the throat Nasopharynx Oropharynx Laryngopharynx • A passageway for food, liquids, and air
Esophagus • Muscular tube located behind the trachea • About 10 inches long • Transports food from the pharynx to the stomach • Upper and Lower esophageal sphincters
Stomach • J-shaped pouch located below the diaphragm • Chemical digestion of protein occurs in the stomach due to gastric juice secretion • Mechanical digestion occurs in the stomach due to maceration (churning).
Pancreas
Small Intestines • • Chemical digestion of nutrients and absorption of nutrients is completed in the small intestines (ave. 22. 5 feet in adults) Three divisions of the small intestines: – – – Duodenum – first portion (10 -15”) where the majority of chemical digestion occurs (Brunner’s Glands- mucus/enzymes) Jejunum – middle portion (8’) where the majority of absorption of nutrients occurs. Ileum – final portion (12’) where absorption occurs.
Large Intestines • The large intestines are the last part of the digestive system. • Absorption of water, vitamins, electrolytes, production of vitamin K, and formation of feces occurs in the large intestines • Ascending, Transverse, Descending, Sigmoid colons
Rectum • The last portion of the large intestine which functions as a temporary storage of solid wastes before excretion
Anus • The final portion of the rectum where solid waste is excreted from the body
