heart structures

The functions of the circulatory system

Transport of gases and hormones, regultes body temp, protection from blood loss

Coronary arteries

Branch off the aorta and carry oxygenated blood to cells of the heart

Coronary viens

Transport deoxygenated blood to cells of the heart into the right atrium

Chordae tendinae

Attach to AV valves to papillary muscles in the walls of the ventricles and prevents valves from inverting

Right AV valve

Controls blood flow between right atrium and right ventricle

Left av valve

Controls blood flow between the left atrium and left ventricle

Aortic semi lunar valves

Prevent backflow of blood from the left vent to aorta

Pulmonary semi lunar valve

Prevents backflow of blood from right ventricle and pulmonary trunk

Oxygenated blood pathway

Pulm viens,left atrium left ventricle and aorta

Depxygenated blood pathway

Vena cava,right atrium, right ventricle , pulm artery
