Document Summary
Urea highest concentration comes from protein metabolism. Uric acid comes from metabolism of purines and pyrimidines (dna and rna) Electrolytes small molecules that conduct an electrical charge. Renin important in adjusting blood pressure. Erythropoietin stimulates the red blood cell production in bone marrow. Calciferol active form of vitamin d necessary for absorption of calcium from the intestine. Male urinary system: kidneys, ureter, urinary bladder, urethra, urinary meatus. *females have a greater risk for uti"s: kidneys, ureter, urinary bladder, urethra, urinary meatus. Blood enters kidneys through right and left renal arteries. Glomeruli located throughout the cortex (outer side) of kidney. Renal tubule (pct) is attached to each bowman capsule. *functional unit of the kidney formed by the glomerulus and renal tubule* Vasa recta parts of peritubular capillaries. Blood pressure control: cooperation between blood side and tubule side of nephron. All collecting tubules lead to the renal pelvis. Three steps in formation of urine: glomerular filtration, tubular reabsorption, tubular secretion.
