B3 - The nephron

Question 1

what are the 6 different regions of the nephron minute tubule ?

Answer 1

Glomerulus
Bowman’s capsule
PCT
Loop of Henle
DCT
Collecting duct

Question 2

what is the glomerulus ?

Answer 2

The nephron begins with a group of convoluted blood capillaries called the GLOMERULUS.

Question 3

what is bowman’s capsule ?

Answer 3

The glomerulus is surrounded by a cup shaped structure called the BOWMAN’S CAPSULE

Question 4

what is the PCT ?

Answer 4

The Bowman’s capsule then leads into the longest part of the nephron the PROXIMAL CONVOLUTED TUBUL

Question 5

what is the loop of henle ?

Answer 5

The proximal convoluted tubule then leads into the hairpin shaped structure called the LOOP OF HENLE

Question 6

what is the DCT ?

Answer 6

The Loop of Henle then leads into the DISTAL CONVOLUTED TUBUL

Question 7

what is collecting duct ?

Answer 7

The distal convoluted tubule leads finally into the COLLECTING DUCT

Question 8

what are the two stage processes that kidneys produce urine ?

Answer 8

ultrafiltration and selective reabsorption

Question 9

what is ultrafiltration ?

Answer 9

Firstly small molecules and ions are filtered out of the blood in the glomerulus and into the Bowman’s capsule

Question 10

what is selective reabsorption ?

Answer 10

Any of the ions and molecules that are required by the body are taken back from the nephron and moved back into the blood
