Question

What is the role of valves present in the heart ?

Answer 1

Heart:

• The heart is a part of the body that pumps blood and supplies it to all parts of the body through veins.
• The heart has four chambers - two upper atria (receiving blood ) and two lower ventricles (discharging chambers)

Valves:

• These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart).
• The valve acts as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle.
• The valves control the flow of blood in the heart.
• They prevent the backward flow of blood into the heart.
