Heart Valves:
Valves separate each
chamber of the heart. These
valves open to allow blood to
flow from one chamber or
blood vessel to enter another.
There are four valves
within the heart:
Mitral Valve
Aortic Valve
Tricuspid Valve
Pulmonic Valve
The valves will be discussed
later on in the manual.
Coronary arteries:
The heart is a muscle and therefore needs blood supply, too! The coronary arteries are the
blood vessels on the heart muscle that power
it.
The right coronary artery (RCA) feeds the
right side of the heart
The left main coronary artery (LMCA)
starts on the left part of the heart and branches
into the left anterior descending artery (LAD)
and the circumflex artery (Cx). These branches
feed the left side of the heart.
