Which system is also referred to as the circulatory system?

The circulatory system is more formally known as the cardiovascular system, which is responsible for the transportation of blood, nutrients, oxygen, carbon dioxide, and hormones throughout the body. This system comprises the heart, blood vessels, and blood. The function of the cardiovascular system is critical in maintaining homeostasis and ensuring that all tissues receive sufficient oxygen and nutrients to function effectively while removing waste products.

Understanding the cardiovascular system's role helps in grasping broader topics in the medical field, including how various conditions can affect circulation and overall health. The other systems mentioned do not primarily serve this function. For instance, the respiratory system is responsible for gas exchange, while the muscular system enables movement, and the nervous system controls body functions.
