Parts and Function of the Human Heart (With Pics)

What are the different types of blood

A, B, AB, O

Septum

Divides the right and left chambers of the heart

Myocardium

Muscle tissue of the heart; Receives oxygenated blood from lungs to the left atrium

Coronary Arteries

The artery that originates in the aorta; Supplies the heart muscle with oxygenated blood

Right ventricle (RV)

The chamber of the heart that pumps oxygen-poor blood to the lungs

Aorta

The largest artery in the body; it conducts freshly oxygenated blood from the heart to the tissues.

Cardiovasuclar system

The system of heart and blood vessels that circulate blood throughout the body

Right atrium (RA)

This chamber of the heart receives deoxygenated blood from the body (from the superior and inferior vena cava's.

arteries

blood vessels that carry blood away from the heart

veins

blood vessels that carry blood back to the heart

Pulmonary veins

blood vessels that carry oxygenated blood from the lungs to the left atrium

Left pulmonary artery

carries poor oxygenated blood from the right ventricle to the lungs.

Pulmonary circulation

circulation of blood between the heart and the lungs

Systemic circulation

circulation that supplies blood to all the body except to the lungs

Inferior vena cava

large vein that brings oxygen poor blood from lower regions of the body to right atrium

Superior vena cava

large vein that brings oxygen-poor blood from the upper parts of the body to the right atrium

Tricuspid valve (TV)

located between the right atrium (RA) and right ventricle (RV)

Mitral valve (MV)

located on the left side of the heart between the left atrium (LA) and the left ventricle (LV)

Left ventricle (LV)

receives blood from the left atrium and pumps the blood into the aorta for transport to the body cells

Right pulmonary artery

takes oxygen poor blood from the right ventricle to the right lung

Left Atrium

the left atrium receives oxygenated blood from the pulmonary veins which brings purified blood from the lungs

Aortic valve

this heart valve is between the left ventricle and the aorta and it allows oxygen-rich blood to pass from the left ventricle into the ascending aorta
