Blood enters the right atria from the superior and inferior vena cava. Then it flows down into the right ventricle. Then to the lungs. Back to the left atria. Down into the left ventricle and out the the rest of the body.
From the left ventricle.
In the pulmonary circulation, deoxygenated blood leaves the right section of the heart through the pulmonary artery, enters the lungs and oxygenated blood comes through the pulmonary veins. The blood then moves to the left atrium of the heart.
Are you using this instead of doing homework? Blood comes back into the heart from the lungs via the Pulmonary vein into the Left Atrium.
The right atrium is where the blood enters the heart.
When blood leaves the lungs through the pulmonary veins, it returns to the heart and enters the left ventricle.
Blood returning from the body systemic circulation first enters which chamber of the heart?
blood used by the body enters the right atrium
From the left ventricle.
Atrium
The chamber where blood first enters the heart is called the right atrium. It receives deoxygenated blood from the body through the superior and inferior vena cavae. From the right atrium, the blood then flows into the right ventricle, which pumps it to the lungs for oxygenation.
It enters the right chamber called right atrium
In the pulmonary circulation, deoxygenated blood leaves the right section of the heart through the pulmonary artery, enters the lungs and oxygenated blood comes through the pulmonary veins. The blood then moves to the left atrium of the heart.
Blood returns to the heart via the pulmonary veins and it enters into the left atra.
throught the Superior and Inferior Vena Cave and into the Right Atrium
