Document Summary
Urinary system helps to excrete wastes and maintain a balance of chemicals and water in the body. Urinary system includes: kidneys, ureters, bladder, and urethra. The kidneys filter and regulate o o o o o o o o o. Filter metabolic wastes, toxins, excess ions, and water from the bloodstream, and excrete them as urine. Regulate: blood volume, blood pressure, electrolyte levels, and acid base balance. Done by selectively reabsorbing water and other substances. Produce: erythropoietin, secrete the enzyme rennin and activate vitamin d3. Location: against the posterior abdominal wall behind the peritoneum. Nephron= basic structural and functional unit of the kidney. Renal arteries bring blood to the kidneys and into the glomeruli. Blood pressure forces plasma, dissolved substances, and small proteins out of the porous glomeruli into bowman"s capsule to form filtrate. Glomerular filtration rate= the amount of filtrate formed by the kidneys per minute. Filtrate moves from bowman"s capsule into the proximal convoluted tubule.
