The right-hand side of the heart receives de-oxygenated blood from the body tissues (from the upper- and lower-body via the Superior Vena Cava and the Inferior Vena Cava, respectively) into the right atrium. This de-oxygenated blood passes through the tricuspid valve into the right ventricle. This blood is then pumped under higher pressure from the right ventricle to the lungs via the pulmonary artery.
The left-hand side of the heart receives oxygenated blood from the lungs (via the pulmonary veins) into the left atrium. This oxygenated blood then passes through the bicuspid valve into the left ventricle. It is then pumped to the aorta under greater pressure (as explained below). This higher pressure ensures that the oxygenated blood leaving the heart via the aorta is effectively delivered to other parts of the body via the vascular system of bllod vessels (incl. arteries, arterioles, and capillaries).

Nevrous system controlling heart pupils of the eye etc?
The nervous system controls the heartbeat by sending electrical signals through the heart's specialized cells. Pupil size is regulated by the autonomic nervous system, with the sympathetic system dilating the pupils and the parasympathetic system constricting them. Overall, the nervous system plays a crucial role in regulating various bodily functions, including heart rate and pupil size, to maintain homeostasis.

What type of scientist studies heart and its function?
A cardiologist is a medical doctor who specializes in the heart and its functions. A cardiac physiologist is a scientist who focuses on the heart's electrical system and how it functions to pump blood throughout the body.
Do the heart functions as four separate pumps?
You could say that, but you could say it functions as two pumps or one. As four pumps the (1)left and (2)right atrium pump blood into the left and right ventricles. Then the Left and Right ventricles pump blood into the (3)lungs and (4)body respectively. Looking at the heart as two pumps, the atriums (L and R) pump into the ventricles. As one pump, the heart circulates the blood in the body.
