questions well answered to pass
Anatomical features of the kidney - correct answer ✔✔Reddish-brown bean-shaped organ
Size of small fist
Enclosed in a tough, fibrous capsule
Left kidney is slightly higher than the right kidney
Surrounded by connective tissue (renal fascia) and masses of adipose tissue (renal fat)
Blood pathway in kidney - correct answer ✔✔Renal artery
Segmental artery
Interlobar artery
Arcuate artery
Cortical radiate artery
Afferent arteriole
Glomerulus
Efferent arteriole
Peritubular capillaries
—From the nephron, venous blood returns to the renal vein through:
Cortical radiate veins
Arcuate veins
Interlobar veins
Segmental veins
Renal veins
, Renal tubule pathway (after filtrate leaves the Bowman's capsule) - correct answer ✔✔Proximal
convoluted tubule —> Nephron loop —> distal convoluted tubule —> collecting duct
nephron components - correct answer ✔✔RENAL CORPUSCLE:
—Glomerulus: cluster of capillaries (filters blood- 1st step in urine formation)
*afferent arteriole — glomerulus — efferent arteriole
—Glomerular (Bowman's) capsule: receives filtrate from glomerulus
RENAL TUBULE:
—extends from Bowman's capsule to collecting duct
*Glomerular capsule — proximal convoluted tubule — Nephron loop (loop of Henle) — distal
convoluted tubule
renin-angiotensin system - correct answer ✔✔System located in the kidney that helps to
regulate fluid balance and blood pressure.
vasoconstriction, ADH secretion, and aldosterone lead to a conservation of Na+ and water, and
an INCREASE in blood pressure
helps keep GFR constant
juxtaglomerular apparatus - correct answer ✔✔Specialized cells next to the glomerulus that
help to regulate blood pressure
**Regulates the secretion of renin
When renin is secreted it regulates the renin-angiotensin system, which INCREASES blood
pressure
What does angiotensin II do? - correct answer ✔✔stimulates the adrenal glands to secrete
aldosterone
Causes increased thirst
