Anatomy

ELECTRICAL SYSTEM

The heart has its own electrical system. Its function is to synchronize the muscle contraction in an effective way.

TRICUSPID VALVES

There are 2 heart valves called tricuspid. One is the Pulmonary valve and the other is the Aortic valve.

HOW IT IS MADE (ANATOMY)

The heart is a muscular organ located in the center of the chest, between the two lungs.

ATRIOVENTRICULAR VALVES

There are two valves separating the ventricles from the atria. They are called atrioventricular valves.

THE FIBROUS SKELETON

Just like the human body, the heart has its own skeleton.

CORONARY ARTERIES

The heart is a muscle that relies on oxygen to work properly. The delivery of this invaluable fuel is provided by the coronary arteries.

THE SYSTEMIC CAPILLARIES

The systemic capillaries are the junction points between the arteries and the veins of the great circulation. It is at that this microscopic level that breathing and feeding of the cells of the human body occur.

PULMONARY CAPILLARIES

Red blood cells are filled with oxygen at the level of the pulmonary capillaries. They are the junction between the small arteries and veins of the pulmonary circulation. It is at that microscopic site that ‘’respiration” really occurs.
