Cardiovascular System

Heart - pumps blood containing oxygen, nutrients, waste and hormones around the body

​Red blood cells - carry oxygen from lungs to tissue

White blood cells - protect against disease​

Platelets - help the blood to clot​

Plasma - liquid part of the blood that carries cells and proteins throughout the body

Right atrium - receives blood low in oxygen from the body and then empties the blood into the right ventricle

Right ventricle - pumps blood low in oxygen to the lungs

Left atrium - receives blood full of oxygen from the lungs and then empties the blood into the left ventricle

Left ventricle - pumps blood full of oxygen out to the body

Aorta - the main artery that carries blood away from your heart to the rest of your body

Vena cava - a large vein that carries blood to the heart from other areas of the body

Pulmonary valve - controls the flow of blood low in oxygen from the heart to the lungs

Pulmonary artery - carries blood low in oxygen from the right side of your heart to your lungs.

Systemic circulation - the circulation of blood in which oxygenated blood is pumped from the heart to the body and deoxygenated blood is returned back to the heart

Pulmonary circulation - the circulation of blood between the heart and the lungs

Arteries - carry oxygenated blood away from the heart

Veins - carry deoxygenated blood to the heart

Capillaries - transports blood, nutrients and oxygen to cells in the body

Double circulatory system - blood passes through the heart twice per circuit
