Which system is responsible for transporting nutrients, gases, and waste products throughout the body?

The circulatory system is vital for maintaining homeostasis and supporting the body's functions by transporting essential substances. It is composed of the heart, blood, and blood vessels. The heart pumps oxygenated blood from the lungs throughout the body, delivering nutrients to cells while also carrying carbon dioxide and other waste products back to the lungs and kidneys for removal. This system effectively enables communication and the distribution of vital elements necessary for life, including hormones and immune cells, which are crucial for protecting the body and ensuring proper functionality. The intricate network of arteries, veins, and capillaries facilitates this essential transport process, highlighting the circulatory system's primary role in sustaining overall health and physiological balance.
