Abstract:
The present study was made in the anatomy laboratory on 100 heart specimens. It was studied the morphological parameters about diameter and number of the atrial orifices of the pulmonary veins. The number of the orifices and their diameter depends on the lungs weight. Generally (70% of the cases) the orifices number is four and rarely three or five. An increased number of orifices are more frequently in the right side and a decreased number especially in the left side. The orifices diameter is much larger at the male's veins than the female's ones, and much larger in the right than the left side and also much larger at the superiors than the inferior veins.

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...

What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system as it...
Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
