Question
What is the first structure that blood will enter after it has exited the right atrium?
- Multiple Choice
- left atrium
- pulmonary artery
- aorta
- right ventricle
Solution
To determine the first structure that blood will enter after it has exited the right atrium, we need to consider the pathway of blood flow in the heart.
- Understanding Blood Flow: Blood flows from the body into the right atrium, and upon contraction, it moves into the right ventricle.
- Pathway of Blood: From the right ventricle, blood is pumped through the pulmonary artery to the lungs for oxygenation.
Conclusion:
The correct answer is right ventricle. Blood exits the right atrium and enters the right ventricle next in the circulatory pathway.
