Concept Map 12: Digestive and Urinary System Ashley Thompson
Major Functions of Digestive System
Carries out process of digestion
Mechanical digestion: breaks down large pieces of food into smaller ones; chemical composition; not changed by process
Chemical digestion: breaks down large nutrient molecules into smaller ones; by breaking chemical bonds
breaks down food and absorbs nutrients during digestion
Major Functions of Urinary System
Filters salts and wastes from the blood
Helps maintain normal concerntrations of electrolytes and water
Regulates pH and body fluid volume
Helps control red blood cells production and blood pressure
Digestive Enzymes
Salivary amylase: function: breaks down starches and dissacarides
Pepsin: functions: begins protein digestion
Pancreatic amylase: breaks down starch into dissacarides
Pancreatic lipase: breaks down fatty acids into glycerol
Protolytic enzymes: break down proteins or partially digested proteins into peptides. Enzymes are: trypsin, chymotrypson, and carboxypeptidase
Nucleases: source: Pancreas, Function: break down nucleic acids into nucleotides
Peptidase: source: Intestinal cells, Functions: breaks down peptides into protein amino acid.
Sucrase, Maltase, and Lactase: source Inestinal mucosal cells, Functions: breaks down dissacarides into monosaccarides
Intestinal Lipase: source: Intestinal mucosal cells, Function: Breaks down fats into fatty acids and glycerol.
Enternokinase: source: Intestinal mucosal cells, Functions: converts trysinogen into trypsin
Major Organs of Digestive System
Mouth, Cheeks, Lips, Tongue, Palate, Teeth, Salivary glands, pharynx, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine,
Major Organs of Urinary System
kidney, ureter, urinary bladder, urethra.
Location of digestion and absorption of each macromolecule
The macromolecules are digested into the small intestine
Protein is digestied from mouth to stomach to small intestine
carbohydrates are absorped in the large intestine
Layers of GI (Gastrointestinal) tract
mucosa: inner layer of Alimentary canal
submoucosa: underneath the mucosa: has blood vessels
muscularis: has 2 layers of muscle wall
serosa: outer layer
Disorder of the Digestive & Urinary System
Cholecystitis: inflammation of the gallbladder, symptons: tender abdomen, nausea
Gastroesophageal Reflux Disease (GERD): chronic complex intestinal condition that causes inflammation in digestive tract
Paptic Ulcers: sores that develop in the lining of the duodenum
Colon disease(2): colorectal cancer uncontrolled cell growth in colon, polyps growth
All Digestive Diseases
Urinary Diseases
Bladder Cancer: when cells in bladder grow abnormally
Urinary Tract Infection (UTI): abnormal growth of bacteria along urinary tract
Kidney Stones: urine contains many dissolved salts and minerals
