Study Notes

Cardiovascular System

The cardiovascular system, also known as the circulatory system, is comprised of the heart and blood vessels.
The heart, a muscular pump, is located in the chest cavity behind the sternum.
The heart is cone-shaped with its base pointing upwards and its apex pointing downwards.
The apex of the heart is positioned opposite the left 5th intercostal space and is formed by the left ventricle.
The heart is supplied by the right and left coronary arteries.
Venous drainage of the heart is achieved by the coronary veins that merge into the right atrium.

Heart Anatomy
