Question

when the right atrium relaxes the blood rushes to ​

Answer 1

(｡◕‿◕｡)

Pulmonary vein

• Blood leaves the lungs and returns to the heart entering the left atrium through two veins called the pulmonary veins. The atrium is relaxed (diastole) as blood enters. As the atrium fills, the pressure inside rises. The mitral valve (between the atrium and ventricle) is closed to stop blood entering the ventricle..

Answer 2

Answer:

Explanation:

As the body relaxes, deoxygenated blood flows from the body to the right atrium. Right ventricle, the comparable lower chamber, expands while the right atrium contracts. As a result, the right ventricle receives the blood and pumps it to the lungs where it is oxygenated.

The right ventricle also unwinds as the left ventricle does. As a result, the tricuspid valve opens and the pulmonary valve closes. This allows blood that the body has returned to the right atrium to flow into the right ventricle.

one of the heart's four chambers. Blood with low oxygen content is taken in from the body by the right atrium, which then pumps it into the right ventricle.
