👉 Circulation fluid, also known as blood, is a complex mixture of water, proteins, electrolytes, nutrients, hormones, and waste products that circulates throughout the body. Primarily composed of water, it carries essential substances like oxygen and nutrients to cells while removing metabolic waste products. This vital fluid is pumped by the heart, a muscular organ that contracts rhythmically to propel blood through a vast network of arteries, veins, and capillaries. The circulatory system ensures that every cell receives the necessary resources for survival and function, while also playing a crucial role in regulating body temperature, immune response, and overall homeostasis.
