Which system is responsible for transporting oxygen and nutrients to tissues?

The circulatory system is responsible for the transportation of oxygen and nutrients to tissues throughout the body. This complex system includes the heart, blood vessels, and blood, which work together to ensure that essential substances are delivered to cells and that waste products are removed. Oxygen is transported primarily by red blood cells, which bind to oxygen molecules in the lungs and carry them through the bloodstream to various tissues.

Nutrients absorbed from digested food, such as glucose and amino acids, are also distributed via the blood. This system plays a vital role in maintaining homeostasis, providing cells with what they need to function properly and survive. The heart acts as a pump to circulate blood, while arteries carry oxygen-rich blood away from the heart, and veins bring oxygen-poor blood back. The overall efficiency of the circulatory system is crucial for the health and functionality of all bodily tissues.
