Basic Cardiovascular Duties
Layers and Chambers of the Heat
~The heart has three layers:
- Endocardium: Inner layer
- Myocardium: Middle layer of muscle
- Epicardium: Outer layer
~The heart has two chambers:
- Upper chamber: Right and left atria
- Lower chamber: Right and left ventricles
Stucture of the Cardiovascular System
~ There are different parts of the heart:
- Arteries: Carry blood, with no oxygen, away.
- Veins: Carry blood, with oxygen, to the heart.
- Valves: Bicuspid, tricuspid, pulmonary, and aortic valves.
- Valves prevent back flow and controls the flow.
The blood vessels travel all throughout the body.
The human heart is a very complex organ and has many important factors.
Heart and Vessels
The heart has many vessels and veins in it, and the veins leave the heart, pumping blood all over the body.
Bradycardia - Slow heart
Carditis - Inflammation of the heart
Myocarditis - Inflammation of the muscle of the heart
Cardiac Arrest - Heart failure
Cardiomyopathy - Disease in the muscle layer of the heart
Heart Failure - The heart stops beating
