Question

What is Atria and Ventricle?​

Answer 1

Explanation:

• The heart has four chambers.
• The upper two chambers are the atria, and the lower two are the ventricles
• The chambers are separated by a wall of tissue called the septum.
• Blood is pumped through the chambers, aided by four heart valves.
• The valves open and close to let the blood flow in only one direction.

= Atria The two thin-walled chambers that receive blood from the veins.

= A ventricle is one of two large chambers toward the bottom of the heart that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs
