Detailed Solution

The heart is a muscular organ in all living things and pumps blood through the blood vessels.
In humans, mammals, and birds, this is a four-chambered, upper left and right atrium, and the lower left and right ventricle.
The deoxygenated blood flows into the right atrium through the vena cava and passes into the right ventricle.
From there, it is pumped into the pulmonary artery and enters into the pulmonary circulation where it gets oxygen from the lungs.
