Major Blood Vessels
Valves
Chambers of he Heart
Conduction System (Electrical System)
200

Exits from the right ventricle to the lungs, carries deoxygenated blood to the lungs for oxygenation.

Pulmonary Arteries

200

Located between the right atrium and right ventricle

Tricuspid Valve

200

This chamber is located in the upper right side of the heart and receives deoxygenated blood form the body via the superior and inferior vena cava and sends it to the right ventricle.

Right Atrium

200

Located in the right atrium and is the natural pacemaker, initiates heartbeat.

Sinoatrial (SA) Node

300

These blood vessels exit from the right ventricle to the lungs and carry deoxygenated blood to the lungs for oxygenation

Pulmonary Arteries

300

This valve is located between the right ventricle and pulmonary artery.

Pulmonary Valve

300

This chamber is located on the lower left side of the heart and pumps oxygenated blood to the entire body through the aorta (Thickest chamber due to higher workload)

Left Ventricle

300

It is located between the atria and ventricles, it delays impulse before passing to ventricles, ensuring atria contract first.

Atrioventricular (AV) Node

300

Connects to the right atrium, it caries deoxygenated blood from the body to the heart

Superior & Inferior Vena Cava

300

This valve is located between the left atrium and left ventricle and prevents the backflow of blood into the left atrium when the left ventricle contracts.

Mitral (Bicuspid) Valve

300

This chamber  is located on the lower right side of the heart and pumps deoxygenated blood to the lungs through the pulmonary artery for oxygenation.

Right Ventricle

300

It is located along the septum and ventricles and conducts electrical impulses to cause coordinated ventricular contractions.

Bundle of His, Bundle Branches, Purkinje Fibers

400

This vessel arises for the left ventricle and distributes oxygenated blood to the entire body.

Aorta

400

This valve is located between the left ventricle and the aorta, it prevents backflow of blood into the left ventricle after it's pumped into the aorta.

Aortic Valve

400

This chamber is located on the upper left side of the heart, and receives oxygenated blood from the lungs via the pulmonary veins and sends is it to the left ventricle.

Left Atrium

400

It is the outer protective sac surrounding the heart and protects and anchors the heart, reduces friction during heartbeat.
