Term
Primary Function
Definition
Regulation of blood composition, volume, and pressure.
Term
Lower Right
Definition
Right kidney is lower because of the liver having a bigger right lobe.
Term
Retroperitoneal
Definition
not located in abdominal cavity
Term
Renal Calculi
Definition
Kidney Stones, formed from high levels of solutes/ions in body and dehydration. over activity of parathyroid gland which makes more calcium in blood.
Term
Urethral Sphincters
Definition
Internal = involuntary
External = voluntary
Term
Calcium
Definition
Bones, Muscle contraction
Term
Sodium and Potassium
Definition
depolarize and repolarize with nerve conduction
Term
Chloride
Definition
Nerve conduction, pH
Term
Kidneys raise blood pressure... how?
Definition
kidneys produce renin, renin activates angeotensin causing vasoconstriction, angeotensin goes to adrenal cortex which makes aldosterone which causes more vasoconstriction and retains water and sodium. Kidneys also retain water.
Term
Kidneys lower blood pressure... how?
Definition
regulate water in blood... less water = less pressure.
Term
Ace Inhibitors
Definition
block angeotensin production
Term
Kidney Hormone Production
Definition
Calcitrol (vitamin D) = keeping calcium in body
EPO = Red Blood Cell Production
Term
Bilirubin
Definition
product of breakdown of rbc's
Term
Renal Hilus (Hilium)
Definition
notch where blood, lymphatic tissues, ureters, and nervous innervation enters kidney
Term
Gluconeogenesis
Definition
kidney function that releases glucose into blood.
Term

Definition
thin layer of tissue anchoring kidney
Term
Adipose Capsule
Definition
intermediate layer of the kidney
Term

Definition
deep layer of kidney tissue
Term
Parenchyma
Definition
Functional part of kidneys. Pyramids + Cortex
Term
Papilla
Definition
Tip of the pyramids
Term
Renal Pelvis
Definition
Where urine is collected from major and minor calyx. Major and minor calyx get urine from papillary ducts.
