Expert Solution
Step 1
The heart is part of the cardiovascular system, that is involved in the pumping and circulation of blood.
It is made of four chambers - left and right atrium - the top chamber
Left and right ventricles - the lower chambers. Blood is pushed from the atrium to the ventricles and then pumped into blood vessels for systemic (to the body) circulation and pulmonary (to the lungs for oxygenation) circulation.
There are valves present between the atrium and ventricles, and the blood vessels to prevent any backflow of blood.
Blood passes through different valves and chambers before being pumped into blood vessels.
Different arteries and veins arise from the heart and return blood to the heart, respectively.
