XI Flashcards
What two compounds are active in hormone regulation?
Aldosterone and ADH
What secretes aldosterone?
The adrenal cortex
Which system regulates aldosterone?
Renin-angiotensin system
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.
ADH increases what?
Collecting duct’s permeability to water, which increases water reabsorption.
Where does ADH have a high solute concentration?
The blood
What secretes ADH?
The posterior pituitary.
The liver has a role in processing what?
Nitrogenous waste (urea)
The liver stores what two compounds?
Iron and B12
The liver synthesizes what?
Bile and blood proteins
Beta oxidation occurs where? What is converted and what is produced?
The liver. Fatty acids are converted to ketones.
The liver is responsible for this process (one word)
Gluconeogenesis
The liver is responsible for the interconversion of these three compounds.
Carbs, fat, and amino acids.
