👉 The understood fluid, often referred to as bodily fluids, encompasses all the liquids and semi-liquids present within or around the human body. This includes blood, lymph, synovial fluid, cerebrospinal fluid, and various secretions like mucus and saliva. Blood, for instance, is a vital fluid that transports oxygen, nutrients, hormones, and waste products throughout the body, while lymph helps in immune function and fluid balance. Synovial fluid lubricates joints, and cerebrospinal fluid protects the brain and spinal cord. These fluids play crucial roles in maintaining homeostasis, supporting cellular functions, and facilitating physiological processes essential for overall health.
