👉 Fluid, often referred to as a biological fluid or a bodily fluid, is a substance that circulates within the body's vascular system, playing crucial roles in various physiological processes. These fluids include blood, lymph, synovial fluid, cerebrospinal fluid, and amniotic fluid, each serving distinct functions. Blood, for instance, transports oxygen, nutrients, hormones, and waste products throughout the body, while also participating in immune responses and clotting. Synovial fluid lubricates joints, reducing friction and allowing for smooth movement. Cerebrospinal fluid cushions the brain and spinal cord, protecting them from mechanical injury, while amniotic fluid surrounds and supports developing fetuses in the womb. Overall, fluids are essential for maintaining homeostasis and facilitating the body's complex biological processes.
