Question

Write two functions of two upper chambers of human heart?

Answer 1

• The human heart consists of four chambers. The upper chamber is called an atrium (or auricle), and the lower chamber is called a ventricle.
• The right atrium receives deoxygenated blood from the other body organs and pumps it into the right ventricle. This is then sent toward the lungs for oxygenation.
• The oxygenated blood in the lungs is then received by the left atrium and pumped into the left ventricle.
• Finally, the oxygenated blood from the left ventricle is pumped back to the body.
• So, receiving blood and pumping it into the ventricles are the two functions of the upper chambers of the heart.
