Answer 2

Hey friend......☺

Here is your answer

The heart consists of 4 chambers, 2 atria (upper chambers) and 2 ventricles (lower chambers). Blood passes through a valve before leaving each chamber of the heart. The valves prevent the backward flow of blood. Valves are actually flaps (leaflets) that act as one-way inlets for blood coming into a ventricle and one-way outlets for blood leaving a ventricle. Normal valves have 3 flaps (leaflets), except the mitral valve, which only has 2 flaps.

Hoping it helps
