3

Which system regulates aldosterone?

Renin-angiotensin system

4

What is aldosterone's main function, and what are the consequences of this function?

It stimulates sodium reabsorption and potassium secretion. This increases water reabsorption, blood volume, and blood pressure.

5

ADH increases what?

Collecting duct's permeability to water, which increases water reabsorption.

6

Where does ADH have a high solute concentration?

The blood

7

What secretes ADH?

The posterior pituitary.

8

The liver has a role in processing what?

Nitrogenous waste (urea)

9

The liver stores what two compounds?

Iron and B12

10

The liver synthesizes what?

Bile and blood proteins

11

Beta oxidation occurs where? What is converted and what is produced?

The liver. Fatty acids are converted to ketones.

12

The liver is responsible for this process (one word)

Gluconeogenesis

13
