Digestive and Urinary Tract
digestive enzymes
pepsin
produced in the stomach and breaks down proteins
amylase
produced in the mouth which break down large molecules
pancreatic lipase
produced in the pancreas; breaks apart fats
trypsin
produced in pancreas which break down proteins
deoxyribonuclease and ribonuclease
produced in the pancreas; enzymes breaks bonds in nucleic acids like DNA and RNA
digestive disorders
cholecystitis
inflammation of gall bladder
peptic ulcers
sores that develop in the linning of the stomach
inflammatory bowel disease
inflammation in the digestive tract
colorectal cancer
uncontrolled cell growth
polyps
growths
hemorrhoids
inflamed veins
spastic colon
adnormal abdominal conditions
diverticutis
pouches form on the wall of the colon
nephron anatomy & physiology
physiology
filtration,seperate to water ions and small molecules from the blood, filters out wastes and toxins
anatomy
at the end is a cut shaped structure called Bowmans capsule which surrounds a tuft of capillaries
major organs of the digestive & urinary system
urinary
kidneys
urinary bladder
urethra
ureters
digestive
mouth
stomch
gall bladder
small intestine
pancreas
salivary glands
esophagus
oropharynx
liver
large intestine
major functions
produce vitamins
secrete intestinal juice
passage for food
produces saliva to moisten food into bolus
aid in digestion
layers of GI tract
submucosa
areolar connective tissue containing major blood vessel
submucosal plexus
muscularis layer
inner circular layer
outer longitudinal layer
mucosa
mucosa membrane which produces mucus for reduction of friction
stomch
cardiac region which is near the heart
chemical digestion
serosa
outer covering of the GI tract
serous membrane produces serous fluid
location of digestion & absorption of each macromolecule
ingestion
taking in of food through the mouth
peristalsis
propulsion by contraction and relaxation of smooth muscles lining of the alimentary canal
digestion
process of breaking down larger food molecules into smaller molecules
mechanical digestion
physical breakdown of food by cutting and grinding
chemical digestion
requires enzymes
