👉 Fluid, or bodily fluids, are essential components of the human body, categorized into two main types: blood and other secretions like mucus, sweat, and tears. Blood, the most complex fluid, circulates throughout the body via the circulatory system, transporting oxygen, nutrients, hormones, and waste products. It's composed of plasma, red blood cells, white blood cells, and platelets. Other secretions play vital roles in maintaining bodily functions: mucus lubricates and protects surfaces like the respiratory and digestive tracts, sweat regulates body temperature through evaporation, tears provide lubrication and remove debris from the eyes. Each fluid type has specific functions, contributing to overall health and homeostasis.
