👉 Fluids, including blood, lymph, and various bodily fluids like saliva, mucus, and synovial fluid, are essential for maintaining the body's homeostasis. Blood, the most significant fluid, transports oxygen, nutrients, hormones, and waste products throughout the body via its components: plasma (the liquid matrix), red blood cells (carrying oxygen and carbon dioxide), white blood cells (defending against infections), and platelets (involved in clotting). Lymph, a clear fluid with proteins and immune cells, circulates through lymphatic vessels to drain excess interstitial fluid, absorb fats from the digestive system, and support immune responses. Saliva, mucus, and synovial fluid serve specialized functions: saliva aids in digestion, lubrication, and oral health; mucus protects and lubricates surfaces like the respiratory and digestive tracts; and synovial fluid reduces friction in joints, ensuring smooth movement. Each fluid plays a vital role in sustaining bodily functions and overall health.
