Systemic Circuit
_______ is a hollow, cone-shaped, muscular pump
heart
heart chambers that functions as blood storage
Two atria
heart chambers that functions as a low pressure pump and a high pressure pump
Two ventricles
the tough outermost layer of your pericardium. It is made up of connective tissue that prevents your heart from extending too much. It attaches to the great blood vessel on the top of your heart and at the central tendon of the diaphragm at the bottom portion of the heart.
Fibrous pericardium
Layer of serosa that lines the fibrous pericardium
Visceral (Pericardial) pericardium
the outer layer of the pericardium which is conical in structure and surrounds the heart and the roots of the great blood vessel.
Parietal pericardium
3 walls of the heart
epicardium
myocardium
endocardium
also called visceral pericardium. The outermost layer of the wall of the heart. It forms a protective outer covering and it secretes a serous fluid.
Epicardium
the middle layer of the walls of the heart. It is primarily composed of muscles. It is the one responsible in contracting
Myocardium
It is responsible in receiving blood from inferior and
superior vena cava and coronary sinus.

Superior Vena Cava
blood from the lower body enters the ______
Inferior Vena Cava
It is responsible in receiving blood from the pulmonary veins
