It is a hollow, highly muscular, cone-shaped structure located in the thoracic cavity above the diaphragm in between the two lungs. It is protected by rib cage. The narrow end of the triangular heart is pointed to the left side, during working this end gives a feeling of the heart being on the left side.

Heart is right in the centre between the two lungs and above the diaphragm in the ribcage. The narrow end of the roughly triangular heart is pointed to the left side and during working the contraction of the heart is most powerful at this end giving a feeling of the heart being on the left side.

The space between the two layers is filled with fluid called pericardial fluid. This fluid protects the heart from external pressure, push, shock and reduces friction during the heart beat and facilitates free heart contraction.

The heart consists of four chambers. The two thin walled auricles which are upper chambers right and left. Right and left auricles are separated from each other by an inter-auricular septum. Right auricle receives deoxygenated blood from the body parts by anterior and posterior vena cava.

The two thick walled lower chamber right and left are called ventricles. Right and left ventricles are separated by an inter-ventricular septum. The walls of left ventricle are much thicker as it supplies blood to large distance and up to the brain against gravity.

The left ventricle has chordae tendinae and papillary muscles which prevent tricuspid and bicuspid valves from being pushed into auricles at the time of ventricular contraction. Blood Vessels Entering and Leaving the Heart: It brings deoxygenated blood from anterior body parts head, neck, chest and arms to the right auricle.

It brings deoxygenated blood from posterior or lower body parts i.

Valves in the Heart: Right atrio-ventricular valve Tricuspid valve -Located at the opening between right auricle and right ventricle. Present at the opening of right ventricle into pulmonary artery. Located at the point of origin of aorta from left ventricle.

Pacemaker tissues of the Heart: Sino Atrial Node S. It is located at the junction of superior vena cava with right auricle it initiates and maintains the myocardial activity and its rhythmicity, called pace maker of heart. Located posteriorly on right side of the interatrial septum near coronary sinus, in the destruction of S.

The function of pace maker can be taken up by the A. Node along interventricular septum at the top. Impulses travel along bundle of HIS on to ventricles. Located at the terminal divisions of right and left branch of the bundle of HIS.
