👉 A cool fluid, often found in the human body, is blood, which is a vital component of our circulatory system. This complex mixture primarily consists of water, but it also contains red and white blood cells, platelets, and various proteins. Blood serves multiple critical functions: it transports oxygen from the lungs to all body tissues, carries nutrients absorbed from food, and delivers hormones that regulate various bodily functions. Additionally, it plays a key role in immune defense by transporting white blood cells that fight infections and removing waste products. The term "cool" refers to its typically lower temperature compared to other bodily fluids, but this property is not due to being cold in the literal sense; rather, it's a result of its composition and how it helps maintain the body's internal temperature.
