Increased intraventricular pressure
Depolarization at the AV node
Ventricular relaxation and backflow of blood
Contraction of the atria
Decreased peripheral resistance
Increased heart rate
Decreased venous return
It contains sufficient fluid to provide a protective cushion for the heart.
It is a potential space containing a very small amount of serous fluid.
It is lined by the endocardium.
It is located between the double-walled pericardium and the epicardium.
Rapid emptying of the right side of the heart
Forceful action of the valves in the veins
Contraction and relaxation of skeletal muscle
Peristalsis in the large veins
