👉 A brings fluid, commonly known as blood, is a vital component of the circulatory system that transports essential substances throughout the body. Primarily composed of red and white blood cells, platelets, and plasma, it serves multiple critical functions: delivering oxygen and nutrients to tissues, removing waste products, regulating body temperature, and fighting infections. The fluid nature of blood allows it to efficiently carry these substances via its network of vessels, ensuring that every cell receives the necessary resources for optimal functioning. Its composition and flow are regulated by the heart, which pumps it through arteries, veins, and capillaries, maintaining homeostasis and supporting overall health.
