Which system includes the heart and arteries?

The circulatory system is responsible for transporting blood, nutrients, oxygen, and hormones throughout the body. It consists primarily of the heart, blood vessels, including arteries, veins, and capillaries. The heart functions as a pump, circulating blood through the network of arteries that carry oxygen-rich blood away from the heart to the tissues and organs. This system plays a critical role in maintaining homeostasis and overall health by ensuring that essential substances reach every part of the body.

In contrast, the musculoskeletal system focuses on providing structure and support to the body through bones and muscles. The nervous system is involved in transmitting signals throughout the body, coordinating actions and responses. The digestive system is tasked with the breakdown of food and absorption of nutrients. Each of these systems plays a distinct and essential role in body function, but only the circulatory system encompasses both the heart and arteries.
