Which of the following indicates the correct flow of blood between the heart and the lungs?

Sure! To determine the correct answer, let's break down the path of blood between the heart and the lungs step by step:

1) Starting from the heart, the blood first leaves the heart through the pulmonary artery. This is the vessel that carries deoxygenated blood from the heart to the lungs.
2) The blood then enters the capillaries, which are tiny blood vessels located in the lungs. It is in the capillaries where the exchange of oxygen and carbon dioxide takes place - oxygen is picked up and carbon dioxide is released.
3) After passing through the capillaries in the lungs, the blood then enters the pulmonary veins.
4) Finally, the blood returns to the heart by entering the left atrium, completing the circuit.

Based on this information, let's review the answer choices:

1) heart-capillaries-veins-arteries-heart: This option is incorrect because the blood does not flow back to the heart through the arteries after it reaches the capillaries in the lungs.

2) heart-arteries-veins-capillaries-heart: This option is incorrect because it suggests that the blood travels from the heart to the arteries, then to the veins, and finally to the capillaries. However, in the pulmonary circulation, the blood first reaches capillaries before entering veins.

3) heart-arteries-capillaries-veins-heart: This option correctly describes the path of blood between the heart and the lungs. The blood leaves the heart through the pulmonary artery, then goes to the capillaries in the lungs, and finally returns to the heart through the pulmonary veins.

4) heart-veins-capillaries-arteries-heart: This option is incorrect because the blood does not flow from veins to capillaries and then to arteries. In the pulmonary circulation, the blood travels from the heart, through the arteries, to the capillaries, and then to the veins.

Based on the explanation above, your instinct was correct! Option #3, "heart-arteries-capillaries-veins-heart," is the correct answer. Well done!
