Heart Anatomy
Upper Chamber:
Left Atria
-
Blood flow from the veins is deposited into the left atrium where it passes through mitral valve into the left ventricle.
-
Right Atria
-
Main anatomical features of the right atrium include the sinus venarum which surrounds the opening of the superior and inferior cavae.

The Cardiac Cycle
Diastol Phase
-
Oxygen depleted blood returning to the heart from the body passes through the superior and inferior vena cava & flows to the right atrium
-
-
Impulses from the sinoatrial node travel to the (AV) node and the av node sends signals that trigger both atria to contract
-
-
Systol Period
-
The ventricles receive impulses from fiber branches which carry electrical impulses to the ventricles causing them to contract
-
Ventricular contraction causes oxygen depleted blood along the pulmonary circuit to the lungs , there blood picks up oxygen & is returned to the left atrium of the heart by the pulmonary veins
