The muscular wall of this chamber is thicker to pump blood into various organs.
What is the right ventricle?
This blood vessel carries oxygen-rich blood from the lungs to the heart.
What is the pulmonary vein?
This hormone helps regulate blood pressure by controlling water and salt balance.
What is aldosterone?
The thick and elastic walls of arteries allow them to withstand this.
