Digestive System: Overview

• (^) The alimentary canal or gastrointestinal (GI) tract digests and absorbs food
• (^) Alimentary canal – mouth, pharynx, esophagus, stomach, small intestine, and large intestine
• (^) Accessory digestive organs – teeth, tongue, gallbladder, salivary glands, liver, and pancreas

Digestive System: Overview Figure 23. 8

Digestive Process Figure 23.

Gastrointestinal Tract Activities

• (^) 1) Ingestion – taking food into the digestive tract
• (^) 2) Propulsion – swallowing and peristalsis
  • (^) Peristalsis – waves of contraction and relaxation of muscles in the organ walls
• 3) Mechanical digestion – chewing, mixing, and churning food

Gastrointestinal Tract Activities

• (^) 4) Chemical digestion – catabolic breakdown of food
• (^) 5) Absorption – movement of nutrients from the GI tract to the blood or lymph
• (^) 6) Defecation – elimination of indigestible and unabsorbed solid wastes

Liver

• (^) Superficially has four lobes – right , left , caudate , and quadrate
• (^) The largest gland in the body

Liver: Associated Structures

• (^) The lesser omentum anchors the liver to the stomach
• (^) The hepatic blood vessels enter the liver at the porta hepatis
• (^) gallbladder - rests in a recess on the inferior surface of the right lobe; stores bile for digestion of fats

Bile Bile leaves the liver via:

• (^) Bile ducts, which fuse into the common hepatic duct
• (^) The common hepatic duct, which fuses with the cystic duct
  • (^) These two ducts form the bile duct

Liver: Microscopic Anatomy lobules are hexagonal shaped and the structural and functional units of the liver

• (^) Composed of hepatocyte (liver cell) plates radiating outward from a central vein
• (^) Portal triads are found at each of the six corners of each liver lobule portal triads consist of a bile duct and
• (^) Hepatic artery – supplies oxygen-rich blood to the liver
• (^) Hepatic portal vein – carries venous blood with nutrients from digestive viscera
