Chp 7- Urinary System Flashcards
3 nitrogenous wastes
Urea, creatinine, Uric acid
Function of kidney
- filter Nitrogenous waste
- balance water, electrolytes and acids
- release hormones
- degrade and eliminate hormones from blood stream
Hormones release by kidney (3)
Renin, Erythroprotein, Calciferol
Renin
enzyme important in adjusting BP
Erythroprotein
stimulates red blood cell production in bone marrow
Calciferol
active form of Vit D needed for absorption of calcium from intestine
How do kidneys produce urine
- blood enters from renals arteries
- Arterioles carry B to capillaries
- Glomeruli filter blood→Glomerular (bowman) capsule surrounding, renal tubule attached (combine to form nephron)
1. Capsule filtration (water, sugar, wastes, salts)
2. tubule reabsorption (water, sugar, sodium)
3. tubular secretion (acids, potassium, drugs)
Calyces or calices
small, cuplike regions of pelvis

cortex
outer region of an organ
hilum
depression in part or organ where blood vessels and nerves enter and leave
Meatus

medulla
inner region of an organ
nephron
functional unit of kidney where filtration, reabsorption, and secretion take place
