The Nephron Structure

Question 1

what is the structure called that the nephron originates from?

Answer 1

-the Bowmans Capsule

Question 2

how does blood enter the Bowmans capsule?

Answer 2

-through the afferent arteriole which is a branch of the renal artery

Question 3

how does blood leave the Bowmans capsule?

Answer 3

-through the efferent arteriole

Question 4

what is the glomerulus and where is it located?

Answer 4

-within the cup of the Bowmans capsule the arteriole forms a tightly coiled knot of capillaries called the glomerulus

Question 5

when blood leave the Bowmans capsule through the efferent arteriole, what happens next?

Answer 5

-it branches to form a capillary network called vasa recta which remains closely associated with the rest of the nephron

Question 6

what does the Bowmans capsule extend into? (TUBE)

Answer 6

-the proximal convoluted tubule or PCT

Question 7

what does the proximal convoluted tubule extend into?

Answer 7

-the loop of Henle which dips down into the medulla

Question 8

what are the two parts of the loop of Henle called?

Answer 8

-the descending part of the limb into the medulla is called the descending limb
-the part exiting the medulla is called the ascending limb

Question 9

what does the ascending limb extend into?

Answer 9

-the distal convoluted tubule

Question 10

what does the distal convoluted tubule join into?

Answer 10

-the collecting duct

Question 11

where does the collecting duct converge?

Answer 11

-at the base of the pelvis and empty their contents (urine) into the ureter which takes it to the bladder
