The Interior of the Heart

Chambers

4 Chambers

Two atria

Two ventricles

Partitioned by the septum - consisting of myocardium lined by endocardium - right and left

Partitioned by valves - into upper atrium and lower ventricle - atrioventricular valves - mitral valve on the left and tricuspid valve on the right

Structure

Interior lined by endocardium - a thin, smooth, glistening membrane - it peermits smooth flow of blood inside the heart. - made of flattened epithelial cells

Valves : cup like structures called cusps - two in mitral valve (left) and three in tricuspid valve (right)

The cusps of the valves are tethered by chordae tendinae to the papillary muscles

The opening into the aorta is guarded by aortic valve

The opening into the pulmonary artery is guarded by pulmonary valve

Applied anatomy

Papillary muscles - affected by infarction - valve not tethered well by chordae tendinae - valve prolapses into the atrium - regurgitation

Sub endocardial infarction

Atrial septal defect

Ventriclar septal defect
