Study Notes

The Mouth

Salivary glands produce serous (watery) fluid and amylase (enzyme) and mucous (thick, protective) fluid.
There are three types of salivary glands: parotid, submandibular, and sublingual.
The mouth contains teeth, which decrease the size of food particles, including:
- Incisors (cutting teeth)
- Cuspids or canines (tearing teeth)
- Bicuspids and molars (grinding teeth)

The Pharynx

The pharynx connects the nasal cavity with the oral cavity for breathing.
It has three divisions: nasopharynx, oropharynx, and laryngopharynx.
The pharynx pushes food into the esophagus.

Swallowing

The process of swallowing involves the coordination of muscle contractions and relaxations.

The Rectum and Anal Canal

The rectum is a storage area for feces (left-over chyme) and is connected to the sigmoid colon.
The anal canal is the last part of the digestive tract, where defecation occurs.
The defecation reflex is stimulated by mass movements and involves the relaxation of anal sphincters.

The Liver

The liver produces bile, which is stored in the gallbladder and released into the common bile duct.
The liver's functions include:
- Detoxification of the blood
- Storage of vitamins and iron
- Production of bile and enzymes

The Gallbladder

The gallbladder's only function is to store bile.
Bile salts break up large fat globules, increasing the absorption of fatty acids, cholesterol, and fat-soluble vitamins.

Common Diseases and Disorders

Appendicitis: inflammation of the appendix, which can be life-threatening if not treated promptly.
Cirrhosis: chronic liver disease, where normal tissue is replaced with nonfunctional scar tissue.
Cholelithiasis: hard deposits of cholesterol or bilirubin in the gallbladder.
Colitis: inflammation of the large intestine, which can be acute or chronic.
Colorectal cancer: arises from the lining of the rectum or colon, and is curable if treated early.
Constipation: difficult defecation.
Crohn's disease: inflammatory bowel disease, typically affecting the small intestine.
Inguinal hernia: portion of the large intestine protrudes into the inguinal canal or, in males, into the scrotum.
Oral cancer: usually involves the lips or tongue, but can occur anywhere in the mouth, and tends to spread rapidly.
Pancreatic cancer: the fourth leading cause of cancer deaths in the U.S.
Stomach cancer: commonly occurs in the cardiac portion of the stomach, and is more frequent in Japan, Chile, and Iceland.
Stomach ulcers: breakdown in the lining of the stomach.

The Small Intestine

Functions: digestion, absorption of nutrients, and segmentation.
Sections: duodenum, jejunum, and ileum.
Mesentery: a double-layered fold of peritoneum that attaches the small intestine to the back of the abdominal wall.

Absorption of Nutrients

Carbohydrates: starches, simple sugars, and cellulose; excess glucose is stored as glycogen.
Lipids: used to make energy when glucose levels are low; triglycerides are the most abundant; excess is stored in adipose tissue.
Proteins: used for growth and tissue repair; vitamins and minerals are essential for various bodily functions.
Vitamins: fat-soluble (A, D, E, and K) and water-soluble; requirements vary.
Minerals: found in bones and teeth, used to make enzymes, cell membranes, and proteins.

Aging and the Digestive System

Decreased motility, absorption, and ability to detoxify blood.
More likely to develop ulcers and cancers.
Sense of taste is altered.
Dietary changes may occur due to isolation, depression, or other age-related factors.
