Blood enters right side of heart
Through the superior and inferior vena cava.
Vena Cava: the large veinous blood vessels which bring deoxygenated blood to the right atrium from all parts of the body. -
Blood goes to right atrium
Atrium: 2 upper chambers are the left and right atrium. -
Blood goes through tricuspid valve
Tricuspid Valve: positioned between right atrium and right ventricle. There are 3 points of attachment -
Blood goes to right ventricle
Ventricle:lower 2 chambers of ther heart
Permit blood flow in 1 direction and close during contractions -
To the pulmonary valve (Semilunar)
Pulmonary Semilunar Valve: found in the opening of the pulmonary artery. Allows bloo to travel from right ventricle to pulmonary artery . -
Blood travels to main pulmonary artery
Pulmonary Artery: takes blood away from the right ventricle to the lungs for oxygen -
Blood travels to lungs
Blood receives oxygen -
Blood travels from lungs to pulmonary veins
Pulmonary Veins: brings oxygenated blood from lungs to the right atrium -
Travels to left atrium
-
Travels to mitral (Bicuspid) valve
Bicuspid Valve: located between the left atrium and the left ventricle. Prevents backflow from left ventricle to the left atrium -
Travels to left ventricle
-
To aortic valve (Semilunar Veins)
Semilunar Veins: located at the orifice of the aorta. Valve permits the blood to pass from left ventricle to the aorta -
Travels to the aorta
Aorta: largest artery in the body. Takes blood away from the left ventricle to the rest of the body -
Blood with oxygen then goes to all the cells of the body
