Answer 4

Efferent and Afferent arteriole

Question 5

What does the medulla contain?

Answer 5

Loop of Henley and the collecting ducts

Question 6

Answer 7

Vasorecta

Question 8

What is difference between PCT and DCT?

Answer 8

PCT has microvilli and absorbs microvilli

Question 9

Answer 10

simple squarmous

Question 11

What is in the juxtaglomerular?

Answer 11

Macular dense cells from DCT and juxtaglomerular cells.

Question 12

What is the function of the juxtaglomerular?

Answer 12

Produces renin and adis in sodium reabsorbtion.

Question 13

What’s the three main regions of the nephron

Answer 13

Renal corpuscle Tubule Collecting tubules

Question 14

What’s the different regions in the tubule?

Answer 14

DCT PCT Loop of henle

Question 15

Decribe the cross section of each part of the tubule?

Answer 15

Question 16

Summarise the funtion of the nephron?

Answer 16

Question 17

Decribe the epithila in urethra and bladder.

Answer 17

Urothelium

Highly folded

Ability to strecth

Umbrella cells create impermeamble barrier to toxins

Smooth muscle layers

Question 18

Which drug classes act on the nephron and what their effect?

Answer 18

Loop directics - Acts on the thick ascending limb, reduces sodium reabsorption.

Thiazide- Acts on the distal convelated tubule, reduces sodium reabsorption.

Potassium sparring directics- acts at aldosterone recptor antagonist in the DCT , increases water reabsorbion and prevents potassium from being lost.
