👉 Fluids, encompassing water and other bodily liquids like blood, mucus, and sweat, play crucial roles in maintaining the body's homeostasis. Water, the most abundant fluid, is vital for regulating body temperature, transporting nutrients and waste products, and facilitating chemical reactions necessary for cellular function. Blood, a type of fluid containing red blood cells, white blood cells, and platelets, acts as the body's transportation system, delivering oxygen and nutrients to tissues while removing carbon dioxide and toxins. Other bodily fluids, such as mucus that lubricates and protects surfaces, and sweat that cools the body through evaporation, also contribute to maintaining optimal physiological conditions.
