👉 Fluids, also known as bodily fluids, are essential components of the human body that play a crucial role in maintaining homeostasis and supporting various physiological functions. These fluids include blood, lymph, synovial fluid, cerebrospinal fluid, and others, each with distinct compositions and functions. Blood, for instance, is a complex fluid composed of plasma and cells like red blood cells, white blood cells, and platelets, which transport oxygen, nutrients, hormones, and waste products throughout the body. Synovial fluid lubricates joints, reducing friction and absorbing shock, while cerebrospinal fluid protects the brain and spinal cord by cushioning them and providing a medium for nutrient exchange. Each fluid's unique properties ensure the proper functioning of organs, tissues, and systems, highlighting their indispensable role in overall health and well-being.
