Cardiovascular System

Describe capilliaries microscopic vessels that join the arterial system with the venous system. Most significant of the blood vessels. Very thin.
Describe the heart A hollow, muscular organ lying in the mediastinum that propels blood to the entire body.
Describe the SA node Located in the upper portion of the right atrium and has its own built in rhythm. Has the ability to initiate and transmit each heartbeat. Sets the basic pace for the cardiac rate. Known as the pacemaker of the heart.
How do veins return blood to the heart? Skeltal muscle contraction gravity respiratory activity valves
How is blood supplied to the heart muscle? By the coronary arteries and their branches
Name the features that influence blood pressure resistance of blood flow in blood vessels pumping action of the heart viscosity (thickness) of blood elasticity of arteries quantity of blood in the vascular system
