b) which chamber receives blood from the lungs?
c) which ventricle is more muscular, the left or the right? explain.
d) a valve is like a “one way street” in the heart that prevents blood from flowing backward. there is a valve between the atrium and ventricle on both the right and left sides of the heart. why do you think valves are important in the circulatory system?
i gave away all my points (43) for

Answer and Explanation:

a) which side of the heart collects blood from the body and pumps it to the lungs?  The right side of the heart via the vena cava receives blood from the body organs into the right atrium. The resulting pressure forces the tricuspid valve to open and blood gets into the right ventricle.

b) which chamber receives blood from the lungs?

The left atrium through the pulmonary vein receives blood from the lungs.It then flows into the left ventricle through bicuspid valve.

c) which ventricle is more muscular, the left or the right? Explain.

The walls of the left ventricle is thicker than the wall of the right ventricle because the left ventricles pump blood under high pressure to the rest of the body and the left ventricle pumps blood a longer distance hence requires more force.

d) a valve is like a “one way street” in the heart that prevents blood from flowing backward. There is a valve between the atrium and ventricle on both the right and left sides of the heart. Why do you think valves are important in the circulatory system? The valves prevent back flow of blood into the ventricles when the ventricles relax.

true is the answer : )

just here for the other one bc they put up with u
