2
Breaks down food into small parts mechanical (physical) & chemical (acids & enzymes) digestion. release food into blood stream for distribution (via the villi in the small intestine) prepare undigested food for elimination Peristalsis – muscular contractions that move food throughout digestive tract
3
mouth – place where digestion begins; food is chewed using teeth and tongue (mastication) made softer/smaller with the help of saliva from the salivary glands esophagus – tube leading from the mouth to the stomach stomach – organ where food is made into a paste called chyme with the help of these enzyme and acid (releases pepsin and hydrochloric acid)
4
gall bladder › organ that produces and stores bile, which is a yellow-brown digestive liquid. › After leaving the gallbladder, bile goes to the small intestine. liver › organ that releases bile in order to break down fats pancreas › organ that aids small intestine in digestion of sugars, carbs, proteins & fats › It is both an exocrine and endocrine gland
5
small intestines › 20 foot coiled tube where absorption of food into blood takes place › fingerlike projections called “villi” help in the process of absorption (capillaries) › Duodenum-segment that breaks down food large intestine › extends below small intestine › undigested food is prepared for elimination from the body.
7
Colon Cancer › cancer of the large intestine › more common in people over 50 Colonoscopy › procedure recommended for people over the age of 50 › checks for polups in the colon which may be early signs of cancer
8
Hepatitis – viral infection of the liver (inflammation) Diabetes › Type 1 – Insulin deficiency/develops in childhood › Type 2 – Insulin resistant/develops in later adulthood as a result of poor diet › Gestational – a woman may develop this during pregnancy by putting too much weight.
9
Appendicitis › inflammation and swelling of the appendix – should it burst, may become life threatening. › Signs are sharp/acute pain in the lower right side of the abdomen – extremely painfully to the touch. You must go immediately to the hospital. Dehydration › the sudden loss of fluids from the body due to excessive exercise, heat or illness. › Signs: thirst, loss of appetite, dry skin (no sweat), dark urine, dry mouth(no saliva), fatigue, and chills. Potentially Fatal.
10
Gastric Bypass Surgery › stomach stapling › stomach is surgically made smaller in order to control weight gain.
11
chew food carefully and slowly cook food thoroughly eat plenty of fiber (fruits, vegetables, whole grains) drink enough water (8 cups every day) reduce amounts of saturated fat and sugar in diet exercise – burn off excess calories and fat
12
