Atria and ventricles in the human heart diagram. The heart sits within a fluid filled cavity called the pericardial cavity. The heart is a muscular organ about the size of a fist located just behind and slightly left of the breastbone.
The anteri or surface of the human heart faces the sternum the posterior surface the base of the cone faces the vertebral col umn and the inferior or diaphragmatic surface rests on the diaphragm. Within the mediastinum the heart is separated from the other mediastinal structures by a tough membrane known as the pericardium or pericardial sac and sits in its own space called the pericardial cavity. The dorsal surface of the heart lies near the bodies of the vertebrae and its anterior surface.
Human heart diagram highlighting the various anatomical structures. Two ventricles and two atria both right and left. Heart anatomy focuses on the structure and function of the heart.
The right and the left region of the heart are separated by a wall of muscle called the septum. The heart is a mostly hollow muscular organ composed of cardiac muscles and connective tissue that acts as a pump to distribute blood throughout the body s tissues. Because the heart points to the left about 2 3 of the heart s mass is found on the left side of the body and the other 1 3 is on the right.

The heart is the organ that helps supply blood and oxygen to all parts of the body. The two upper chambers are called the left and the right atria and the two lower chambers are known as the left and the right ventricles.
Figure 1 shows the position of the heart within the thoracic cavity. The heart has four different chambers. The right ventricle pumps the blood to the lungs for re oxygenation through the pulmonary arteries.
