The circulatory system transports oxygen, nutrients, hormones, and waste products throughout the body. It includes the heart, blood vessels, and blood. By delivering essential substances to cells and removing waste, it supports cellular functions. The circulatory system also helps regulate body temperature, pH levels, and fluid balance, maintaining homeostasis. Diseases like hypertension and atherosclerosis disrupt this balance, highlighting the need for cardiovascular health.

The circulatory system transports blood, nutrients, oxygen, and waste products throughout the body. It helps maintain homeostasis by regulating body temperature, pH balance, and fluid distribution. The heart pumps blood, while blood vessels (arteries, veins, capillaries) distribute it to various tissues. By adjusting blood flow to organs based on needs, it ensures the body's internal environment remains stable, which is essential for proper functioning and overall health.
The circulatory system's primary function is to transport blood, nutrients, oxygen, hormones, and waste products throughout the body. It consists of the heart, blood vessels, and blood. By circulating blood, it ensures that tissues receive essential substances like oxygen and glucose while removing waste products such as carbon dioxide. The circulatory system maintains homeostasis by regulating body temperature, pH balance, and fluid levels. For example, it adjusts blood flow to different body parts to maintain temperature and helps balance electrolytes and fluids in the body, contributing to stable internal conditions despite external changes.
