kidneys secrete what enzyme to regulate blood pressure? | renin |
kidneys regulate absorption of calcium ions by activating vitamin | D |
renal pelvis | located mostly inside renal sinus directs the urine formed by the kidney toward the ureter. |
functional unit of kidney | nephron |
renal arteries transport | large volume of blood to the kidneys |
Blood flow through the kidneys | renal A-interlobular A-arcuate A-cortical radiate A-afferent arteriole-glomerular capillaries-efferent arteriole-peritubular capillaries or vasa recta-cortical radiate vein-arcuate vein-interlobular vein-renal vein |
what are the two major components of a nephron? | renal corpuscle, renal tubule |
the _____ arteriole supplies blood to the nephron | afferent |
from afferent arterioles blood flows into ? | glomerular capillaries |
segments of the renal tubule in order | proximal tubule-nephron loop-distal tubule |
the segment of renal tubule that receives filtrate from the glomerular capsule is the ____ tubule | proximal |
