👉 A designated fluid, often referred to as a biofluid, is a substance produced and regulated by the body that performs essential functions necessary for life. These fluids include blood, lymph, synovial fluid, cerebrospinal fluid, and amniotic fluid, each with specific roles such as transporting oxygen and nutrients, lubricating joints, cushioning the brain, providing a protective environment for the spinal cord and brain, and facilitating fetal development in the womb. Each fluid is carefully controlled by the body's regulatory systems to maintain homeostasis and ensure proper physiological functioning.
