Blood enters the heart through two large veins the inferior and superior vena cava emptying oxygen poor blood from the body into the right atrium.

Where does oxygenated blood enter the heart. Terms in this set 9 1. This unidirectional flow of blood through the heart shows that mammals have a double circulatory system. Blood is pumped into the aorta which carries oxygenated blood around the body.

The oxygenated blood then returns to the heart through the pulmonary veins. Deoxygenated blood enters the heart through the superior vena cava and the inferior vrna cava. From the left atrium blood flows into the left ventricle.

On the surface of the heart there are coronary arteries which supply oxygen rich blood to the heart muscle itself. Oxygenated blood travels from the pulmonary vein to the left atrium. Left side of the heart the pulmonary veins empty oxygen rich blood from the lungs into the left atrium.

Advertising on our site helps support our mission. The pulmonary vein empties oxygen rich blood from the lungs into the left atrium. Oxygenated blood comes from the lungs and enters the heart via the pulmonary vein.

The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body. Highly oxygenated blood enters the heart via the pulmonary veins into the left atrium of the heart.

Blood leaves the right side of the heart via the pulmonic valve and empties into the pulmonary artery. Deoxygenated blood fills the right atrium. The major blood vessels that enter the heart are the superior vena cava the.

Then it flows through the mitral valve and into the left ventricle. Veins return to the heart and normally have relatively deoxygenated blood pulmonary veins are an exception to this rule and have freshly oxygenated blood while arteries go away from the heart.
