Question

Match the steps to the answers that correspond with that step in the pathway of blood flow through the heart.

From the left atrium, the blood flows through the bicuspid, or mitral valve into the left ventricle
The blood flows through the tricuspid valve into the right ventricle

Deoxygenated blood enters the right atrium from the superior and inferior vena cava

Left ventricular contraction forces blood through the aortic valve into the aorta for distribution to the systemic circulation

The oxygenated blood flows through the pulmonary veins from the lungs into the left atrium


From the right ventricle, the blood flows through the pulmonary valve into the pulmonary artery

The right and left pulmonary arteries carry deoxygenated blood to the right and left lungs for gas exchange

The blood releases carbon dioxide as waste and picks up a fresh supply of oxygen

Answer 1

Guessing it means put them in order?

1. Deoxygenated blood enters the right atrium from the superior and inferior vena cava

2. The blood flows through the tricuspid valve into the right ventricle

3. From the right ventricle, the blood flows through the pulmonary valve into the pulmonary artery

4. The right and left pulmonary arteries carry deoxygenated blood to the right and left lungs for gas exchange

5. The blood releases carbon dioxide as waste and picks up a fresh supply of oxygen

6. The oxygenated blood flows through the pulmonary veins from the lungs into the left atrium

7. From the left atrium, the blood flows through the bicuspid, or mitral valve into the left ventricle

8. Left ventricular contraction forces blood through the aortic valve into the aorta for distribution to the systemic circulation

Answer 2
