The Cardiovascular system
On its bigger end, the base of the heart is attached to the aorta, arteries, veins, and the vena cava. The inferior tip of the heart, rests just superior to the diaphragm . The base of the heart is located along the body’s mid line with the apex pointing toward the left side. Because the heart points to the left, about 2/3 of the heart’s mass is on the left side of the body and the other 1/3 is on the right.
