Trace the flow of blood from the time it enters the right atrium until it is pumped into systemic circulation. Include in your answer chambers of the heart, heart valves and blood vessels.

Since this is not my area of expertise, I searched Google under the key words "blood flow heart" to get these possible sources:

In the future, you can use a similar process to get the information you want more quickly,

I hope this helps. Thanks for asking.

To trace the flow of blood from the time it enters the right atrium until it is pumped into systemic circulation, follow these steps:

1. Deoxygenated blood enters the heart through the superior and inferior vena cava, which bring blood from the body's tissues back to the heart. The blood flows into the right atrium.

2. From the right atrium, the blood flows through the tricuspid valve into the right ventricle. The tricuspid valve prevents backflow of blood from the ventricle into the atrium.

3. When the right ventricle contracts, it pushes the blood out through the pulmonary valve and into the pulmonary artery. The pulmonary valve prevents the backflow of blood from the artery into the ventricle.

4. The pulmonary artery carries the deoxygenated blood to the lungs. In the lungs, oxygen exchange takes place, where carbon dioxide is removed, and oxygen is added to the blood.

5. Oxygenated blood returns to the heart through the pulmonary veins. These four veins bring blood from the lungs to the left atrium.

6. From the left atrium, the blood flows through the mitral valve (also called the bicuspid valve) into the left ventricle. The mitral valve prevents backflow of blood from the ventricle into the atrium.

7. When the left ventricle contracts, it pumps the oxygenated blood out through the aortic valve and into the aorta. The aortic valve prevents backflow of blood from the artery into the ventricle.

8. The aorta is the largest artery in the body. It carries the oxygenated blood to the rest of the body through various arteries, arterioles, and capillaries, which supply the body's tissues and organs.

9. In the capillaries, oxygen and nutrients are released to the tissues, while waste products like carbon dioxide are collected.

10. The deoxygenated blood returns to the heart through the veins, starting the cycle again as it enters the right atrium through the vena cava.

I hope this helps to understand the flow of blood through the chambers of the heart, heart valves, and blood vessels!
