question 1 of 10
blood has traveled from the heart to the fingers. which describes the next step of the circulation process?
a. the blood returns to the heart through veins.
b. the blood releases oxygen on the way back to the heart.
c. the blood goes through the liver to be cleaned.
d. the blood travels to the lungs to get carbon dioxide.

Explanation:

In the circulatory system, after blood travels from the heart to the fingers (systemic circulation), it returns to the heart through veins. Oxygen is released in the fingers during systemic circulation, not on the way back. Blood doesn't go through the liver directly after reaching the fingers, and the lungs take in oxygen and release carbon - dioxide, not the other way around as stated in option D.

Answer:

A. The blood returns to the heart through veins.
