6-10 lobes in each adult kidney
2 or 3 pyramidal papilla empty into a minor calyx
2 or 3 minor calyxes empty into a major calyx
Major calyxes empty into the renal pelvis
Renal pelvis empties into the ureterlyx
® interlobar arteries (up renal columns, between lobes)
® arcuate arteries (over pyramids)
® interlobular arteries (up into cortex)
® afferent arterioles
® Glomerulus (cluster of capillaries)
® efferent arterioles (near medulla ® vasa recta)
® peritubular capillaries
® interlobular veins ® arcuate veins ® interlobar veins
Which of the following would cause the highest blood pressure in the glomeruli?
How much of the glomerular filtrate becomes urine?
Beavers have little need to conserve water. Therefore it is expected that they would have ____ than humans.
Increased ADH secretion should cause urine to have:
1) 200 ml urine in bladder - stretch receptors send signal to spinal cord
2) parasympathetic reflex arc from spinal cord - stimulates contraction of detrusor muscle
3) relaxation of internal urethral sphincter
4) voids bladder
