Rider Urinary System
A&P II – Test 3 – Rider
Urinary System:
Q 1. a) What are the different parts of urinary system. The 2 kidneys, The 2 ureters, the Urinary Bladder and the Urethra. b) What is nephron? Name different parts of a nephron. Write absorption and secretion of different parts of a nephron. Nephron: It is the functional part of the kidney, encharged of filtration of blood and eliminates the nitrogenous waste of our bodies. The nephron consists of: functional units; two parts: renal corpuscle (with a two-layerd glomerular capsule that encloses it. They are separated by filtrate collecting capsular space) & renal tubule (Duct that leads away from the glomerular capsule and ends at the tip of the medullary pyramid). The renal tubule …show more content…
-Hematuria: Hemoglobin in the urine.
Water, Electrolyte and Acid-Base Balance: Q 2. A) What are the fluid compartments of the body. How fluid move from one compartment to another?
65% is located in the Intra Cellular Fluid (ICF)
35% is part of the Extra Cellular Fluid (ECF). Out of the 35% in the ECF; 25% is tissue fluid; 8% is blood plasma, lymph and 2% transcellular fluid (including, CSF, synovial, peritoneal, pleural, among others).
Water moves by osmosis from the digestive tract to the bloodstream and by capillary filtration from the blood to the tissue fluid. b) What are the different forms of water gain and water loss in the body?. What are the disorders of water balance.
Metabolic Water: It is the product of aerobic metabolism and dehydration synthesis. About 200ml/day.
Preformed Water: Ingested in foods and drinks every day. About 1,600ml/day. c) Name major cations and anions of the body? What is the most abundant electrolyte (cations) in the ECF(Extra Cellular Fluid) and ICF (Intra Cellular Fluid)? What is the most abundant anions in the ECF and …show more content…
Carbohydrate Absorption
Sodium-glucose transport proteins (SGLT) in membrane help absorb glucose & galactose
Fructose absorbed by facilitated diffusion then converted to glucose inside the cell
Protein Digestion & Absorption
Pepsin has optimal pH of 1.5 to 3.5 -- inactivated when passes into duodenum & mixes with alkaline pancreatic juice (pH 8)
Pancreatic enzymes take over protein digestion by hydrolyzing polypeptides into shorter oligopeptides
Brush border enzymes finish the task producing amino acids that are absorbed into the intestinal epithelial cells amino acid cotransporters move into epithelial cells & facilitated diffusion moves amino acids out into the blood stream
Infants absorb proteins by pinocytosis (maternal IgA)
