What major function does the circulatory system serve?

Metabolism regulation
Transporting nutrients and oxygen
Waste elimination
Hormone production

The correct answer is: Transporting nutrients and oxygen

The major function of the circulatory system is to transport nutrients and oxygen throughout the body. This system plays a vital role in ensuring that all tissues and organs receive the necessary substances to function effectively. As blood circulates, it delivers oxygen from the lungs and nutrients from the digestive system to every cell, which is essential for cellular respiration and energy production. Additionally, the circulatory system aids in the distribution of hormones and the removal of waste products, but its primary and most critical role revolves around the transport of essential nutrients and oxygen. This function is foundational to maintaining homeostasis and supporting life processes, making it the key aspect of the circulatory system's responsibilities.
