Question 21

Renin causes conversion of

Answer 21

Angiotensin to angiotensin I

Question 22

The functional unit of the kidney is the

Answer 22

Nephron

Question 23

What is kidneys function?

Answer 23

Filter blood, excrete waste products and balance solutes and volume

Question 24

Answer 26

A knot of capillaries shrub the renal corpuscle

Question 27

How does the respiratory system compensate for low pH due to a metabolic issue

Answer 32

Fast deep breathes (hyperventilation)

Question 33

Breathing in a bag helps with

Answer 33

Respiratory alkalosis (low CO2, low H+, increases pH)

Answer 34

Kidneys

Question 35

The carbonic acid bicarbonate buffer system cannot compensate for

Answer 35

Changing pH levels when the lungs are not working properly

Question 36

What does renin do?

Answer 36

When blood pressure is low, can’t push a lot of filtrate out and can’t get rid of a lot of waste producers, so renin is released into the bloodstream.

Renin converts angiotensin made in the liver angiotensin I
