lecture 24 kidney function and renal physiology

Question 1

what occurs in the reabsorption in proximal tubule

Answer 1

the first solutes flow out and water follows

Question 2

what occurs in the loop of henle

Answer 2

only water is reabsorbed concentrating during and when it accents the ions reabsorb but no water

Question 3

Reabsorption in distal tubule/collecting duct:

Answer 3

hormonal regulation of solutes and water
ahh and vasopressin lead to insertion of aqua porins increasing water reabsorption

Question 4

what causes adh/vasopressin to be released

Answer 4

release stimulated by decrease of blood erasure, low volume and high osmolarity `

Question 5

what can occur if the loop of henle is longer

Answer 5

the longer the loop means it is enabled to reabsorb more water given more water absorption
