Question

Freshly oxygenated blood enters the heart through the_____ and is

pumped out the____

Answer 1

Answer:

Freshly oxygenated blood enters the heart through the pulmonary vein into the left atrium and is pumped out the left ventricle through the aorta.

Explanation:

Deoxygenated blood is collected from all over the body by the superior and inferior vena cava and enters the top-right chamber of the heart called the right atrium. This blood then flows into the right ventricle where it is carried by the pulmonary artery to the lungs for oxygenation. The oxygenated blood is then carried back to the heart by the pulmonary vein and enters the top-left chamber of the heart called the left atrium. This blood then flows into the left ventricle which pumps the blood into the aorta which carries oxygenated blood to all the other parts of the body.

Answer 2

Freshly oxygenated blood enters the heart through the left atrium and is pumped out the lungs through the pulmonary veins.

Arteries are responsible for carrying this blood from the human heart. The veins on their own part carry blood that has been depleted of oxygen back to the heart.

The oxygenated blood is helpful to the body becasue it aids respiration.
