White blood cells perform most of their functions out of the circulatory system, but they use the blood for ___________.
Correct Answer
transportationExplanation
White blood cells perform most of their functions outside of the circulatory system, such as in tissues and organs, where they fight infections and remove dead cells. However, they still rely on the blood for transportation. The blood carries white blood cells to different parts of the body, allowing them to reach sites of infection or inflammation. Additionally, the blood provides a means for white blood cells to communicate with each other and coordinate their immune responses. Therefore, while white blood cells primarily function outside of the circulatory system, they still depend on the blood for transportation and communication.Rate this question:
