AP II Lab 8: The Excretory System exam with complete

The Urinary system  Principal means of waste elimination other are digestive  Come from metabolism. If not removed can become toxic in body  Kidney main organs that separate metabolic waste from blood  Has 6 total organs: 2 kidneys, 2 ureters, bladder, urethra Reproductive and urinary are closely related by place in the body called urogenital system Kidneys Filter our blood plasma by glomerulus capillaries; help to regulate blood volume by conserving or eliminating fluid; Regulate blood pressure by producing erythropoietin/ regulates to osmolarity of our blood. Weighs 150 grams, 11 cm long 6 wide and 3 cm thick Lateral surface is convex, medial is concave (hilum); blood tissue enter and exit Interior glandular tissue called renal: 2 zones cortex and medulla; cortex dips down into the sinus region of the kidney (renal columns extensions of cortex) renal pyramids rest in the minor palace: each pyramid rest in its on minor calaces. Minor calaces drain everything in the period, blend with major calace, enter the renal pelvis- kidney function is called a nephron. 2 parts renal corpuscle (main filter of body) / system (converts it’s to urine). (major/minor calyx). Renal parenchyma Renal cortex, medulla, columns Urine can provide us with information about the body (urinalysis) Studies both the chemical and physical properties of urine Color of urine depends on the state of the bodies hydration Urocrome (due to hemoglobin break down) Clarity of urine tells us if there’s infection, cloudy urine can mean bacteria in the body Puss in the urine- pyraia Blood in the urine hemotavaOdor of urine is distinctive odor in a fresh sample- in old sample bacteria are able to multiply making the smell stronger
