What are the two pathways of blood through the body?
Understand the Problem
The question is asking about the two major circulatory pathways in the human body, which are the systemic circulation and the pulmonary circulation. The systemic circulation carries oxygenated blood from the heart to the rest of the body, while the pulmonary circulation carries deoxygenated blood from the heart to the lungs for oxygenation.
Answer
Pulmonary circulation and systemic circulation.
The two pathways of blood through the body are the pulmonary circulation and the systemic circulation.
Answer for screen readers
The two pathways of blood through the body are the pulmonary circulation and the systemic circulation.
More Information
Pulmonary circulation is responsible for transporting blood from the heart to the lungs for oxygenation and back. Systemic circulation distributes oxygenated blood from the heart to the rest of the body and returns deoxygenated blood back to the heart.
Tips
It's important not to confuse the pulmonary and systemic circulations with arteries and veins. While arteries generally carry oxygenated blood and veins carry deoxygenated blood, this is reversed in pulmonary circulation.
