What is the term for the complex arrangements of connected tubes that transport blood and nutrients throughout the body?

The circulatory system is the network responsible for transporting blood, nutrients, gases, and waste products throughout the body. It consists of the heart, blood vessels, and blood. The heart pumps blood through a system of arteries and veins, delivering oxygen and nutrients to tissues while also collecting carbon dioxide and other waste products for removal.

This system is crucial for maintaining homeostasis and supporting cellular functions. The role of the circulatory system extends beyond mere transport; it also plays a part in regulating body temperature, pH levels, and fluid balance. Understanding the circulatory system's intricate function helps clarify its importance in the overall physiological processes of the body, distinguishing it from other systems that serve different critical functions, such as respiration, neural signaling, or hormonal regulation.
