Answer 7

calyx

Question 8

Where is the renal sinus

Answer 8

behind the fat at the bottom of the renal column

Question 9

urine comes out of the …

Answer 9

minor calyx

Question 10

what happens after the bowman’s capsule?

Answer 10

filtration
reabsorption
secretion
excretion

Question 11

In this function: the plasma minus all but the smallest proteins is forces by blood pressure through the filtration membrane which is made up of the podocytes and the glomerular capillaries

Answer 11

filtration

Question 12

In this function: substances in the filtrate are returned from the lument of the nephron tubule to the body [the circulatory system].

Answer 12

reabsorption

Question 13

In this function:

substances in the filtrate are removed from the body by being actively transported into the lumen of the nephron tubule.

Answer 13

Secretion

Question 14

This is eliminated from the body by excretion.

Answer 14

urine

Question 15

Answer 17

glomerulus

bowman’s capsule

Question 18

This is a double-walled, spherical structure consisting of visceral and parietal layers separated by the capsular space

Answer 18

The bowman’s capsule

Question 19

These form the visceral wall of the Bowman’s capsule regulate filtration of substances from the capillaries they surround.

Answer 19

Podocytes

Question 20

The glomerulus is a network of capillaries within the ______ _____ through which blood passes
