The Heart Wall has 3 layers. They are the:

1. Endocardium (innermost lining)

2. Myocardium (middle, muscular layer; thickest layer)

3. Pericardium (fibrous, membraneous sac surrounding the heart; outer layer)

The Septum has 2 sections. They are the:

1. Interatrial Septum (seperates the atria)

2. Interventricular Septum (seperates the ventricles)

There are 4 chambers in the heart. They are the:

Right Atrium (blood enters the heart from the body)

Right Ventricle (blood leaves the heart and goes to the lungs)

Left Atrium (blood enters the heart from the lungs)

Left Ventricle (blood leaves the heart and goes to the body)

There are 4 valves in the heart. They are the:

Tricuspid Valve (between RA and RV)

Pulmonary Valve (between RV and Pulmonary Artery)

Mitral/Bicuspid Valve (between LA and LV)

Aortic Valve (between LV and Aorta)

There are 3 types of bloof vessels in the body. They are the:

Arteries (carry oxygenated blood away from the heart)

Capillaries (microscopic vessels where gas exchange occurs)

Veins (carry unoxygenated blood towards the heart)
