The heart and circulatory system are vital for transporting blood throughout the body, delivering oxygen and nutrients to tissues while removing waste products like carbon dioxide. The heart acts as a pump, maintaining blood flow through a network of arteries, veins, and capillaries. This system also plays a crucial role in regulating body temperature and supporting immune function by distributing white blood cells and antibodies. Overall, it ensures that all organs and cells receive the necessary resources to function effectively.
