What is the name of the system that supplies blood throughout the body?

The circulatory system is the network responsible for transporting blood throughout the body. It plays a vital role in delivering oxygen and nutrients to cells while also facilitating the removal of carbon dioxide and waste products. This system includes the heart, blood vessels, and blood, which work together to ensure that tissues receive the necessary substances to function properly and maintain homeostasis.

The heart acts as a pump, pushing blood through a complex system of arteries and veins. Arteries carry oxygen-rich blood away from the heart, while veins return oxygen-poor blood back to the heart. The circulatory system is essential not just for oxygen transport but also for distributing hormones, immune cells, and other important substances that keep the body functioning effectively.

In contrast, the endocrine system is involved in hormone production and regulation, impacting bodily functions like metabolism and growth without directly transporting substances like blood. The nervous system primarily manages communication within the body through nerve signals rather than physical transport. The immune system protects the body against infections but does not supply or circulate blood. Thus, the circulatory system is the key player in the transportation of blood throughout the body.
