What do blood cells primarily function to do?

Store energy
Transport oxygen and nutrients
Reproduce
Eliminate waste

The correct answer is: Transport oxygen and nutrients

The primary function of blood cells, particularly red blood cells, is to transport oxygen from the lungs to the tissues throughout the body. They achieve this through a protein called hemoglobin, which binds to oxygen molecules and carries them effectively. Additionally, blood cells contribute to the transport of nutrients and other substances, playing a vital role in the overall functioning of the circulatory system and maintaining homeostasis. In contrast, while white blood cells are primarily involved in the immune response and help eliminate waste by attacking pathogens, this does not encapsulate the primary role of blood cells collectively. Storage of energy is more a function of protein and fat cells rather than blood cells. Lastly, the reproduction of cells is conducted through processes in bone marrow, not a direct function of blood cells themselves. Thus, option B correctly identifies the essential role of blood cells in the body.
