Digestive and Urinary System- Merari Hernandez Per:5
Digestive System Functios
Carries out process of digestion. Mechanical/chemical breakdown of foods and absorption of nutrients.
Urinary System Functions
Filters salt and water from blood, helps maintain normal concetration of electrolytes and water, regulates pH and body fluid of volume and helps control red blood cell production and blood pressure.
Pepsin- Begins protien digestion
Digestive Enzymes
Salivary amylase- Begins carbohydrate digestion by breaking down starch to disaccharides
Pancreatic Amylase- breaks down starch into disaccharies
Proteolytic enzymes-Break down proteins or partially digested proteins into peptides
Chymotrypsin
Carboxypeptidase
Trypsin
Pancreatic Lipase- breaks down fats into fatty acids and glycerol
Organs of Urinary System
Kidneys- filter blood, ureters-transport urine from kidneys to bladder,
urinary bladder-stores urine, urethra-conveys urine to outside of body.
Disorders of Digestive/Urinary System
Nephrosis
gastroesophageal reflux disease
irritable bowel syndrome,
Organs of Urinary System
Stomach- 5 shapes muscular organ in upper left abdominal quadrant
Esophagus- muscular tube leading from pharynx to stomach
Pharynx- cavity lying posterior to mouth
Pancreas- endocrine and exocrine gland, produces pancreatic juice that aids digestion
Liver- responsible for metabolic activity such as metabolism of carbohydrates ,lipids and proteins
Gallbladder
Pear shaped sac on the inferior surface of liver
Small Intestine
A long tubular organ, runs from stomach to the beginning of large intestine
Large Intestine
Named large because of its diameter is larger than that of the small intestine
Nephron Anatomy
Consists if a renal corpuscle which performs the first step of urine formation. It has a cluster if capillaries of the golmerulus and a glomerular. The renal tube consists of the glomerular capsule, proximal convlted tubule, nephron loop, distal convulted tubule and collecting duct,.
Nephron Physiology
Functional unit of kidney: can produce urine independently
1 million nephrons per kidney
Rectum
a straight section of large intestine which lies next to sacrum
Layers of GI Tract
Mucocsa
Submocusa
Muscular Layer
Serous Layer
