Urinary System Test Questions with
Verified Answers
Blood vessel sequence in kidneys - Ans -Aorta, Renal Artery, segmental artery,
interlobar artery, arcuate artery, cortical radiate artery, afferent glomerular arteriole,
glomerulus (capillaries), Efferent glomerular arteriole, peritubular capillaries and vasa
recta, cortical radiate vein, arcuate vein, interlobar vein, renal vein, inferior vena cava
Blood flow through kidney - Ans -Blood Enters by renal artery, enters into sinus of
kidney, branched into segmental artery, enters column by interlobar artery, go around
cortex arcuate artery, branch into cortex through cortical radiate artery, ends in nephron of
kidney goes to afferent arterioles then to glomerulus, makes efferent arteriole, then
becomes peritubular capillaries, goes back through corresponding vein
Medulla - Ans -contain nephrons; sign of entry for collective duct, pours into minor
calyx, form to make major calyx, collects into ureters
Renal cortex - Ans -most superficial region of the kidney
Renal medulla - Ans -deep to cortex, contains renal pyramids
Renal pyramids - Ans -contain bundles of tiny urine collecting tubules
Renal columns - Ans -separate adjacent pyramids
Renal sinus - Ans -contains renal vessels, nerves, some fat, renal pelvis, and calices

, Renal pelvis - Ans -urine carrying tubes, expanded superior part of ureter, urine flows
into renal pelvis from calices then into ureter; site where calices are attached to
Major calices - Ans -branching extensions of renal pelvis, divide to form minor calices
Minor calices - Ans -enclose papillae of pyramids, collect urine draining from papillae
and empty into the renal pelvis
Renal arteries - Ans -¼ of the heart's systemic output reaches kidneys via these
3 steps Nephron produces urine - Ans -filtration, resorption, and secretion
Filtration - Ans -filtrate of blood leaves the kidney capillaries and enters renal tubule,
processed into urine through renal tubule
Resorption - Ans -nutrients, water, and essential ions are recovered from filtrate and
returned to the blood of capillaries in the surrounding connective tissue
Secretion - Ans -moves additional undesirable molecules into the tubule from the
blood of surrounding capillaries
Nephron - Ans -composed of renal corpuscle and renal tubule
Renal tubule - Ans -proximal tubule, nephron loop (loop of Henle), and collecting
duct; filtration proceeds through here after renal corpuscle
