The cardiovascular system is made up of the heart and blood vessels.
The heart pumps to move blood throughout the body through the pulmonary circulation and systemic circulation.
The heart is composed of three layers.
The epicardium which is the outer lining, the myocardium, which is the main heart muscle, and the endocardium, which is the inner lining. The muscles of the heart sit in a fluid filled sac called pericardial sac. A pericardial window described in CPT code 33025 is an incision made in the percardium to drain fluid that has build up around the heart.
There are three types of blood vessels.
The arteries take blood away from the heart. The veins take blood back to the heart. Capillaries are tiny, semi permeable vessels that facilitate the exchange of fluids,oxygen,nutrients,and waste between local tissues and the blood stream. Coronary Artery Bypass Grafts can be created using veins or arteries.
