👉 Fluids, encompassing both blood and other bodily liquids like synovial fluid and cerebrospinal fluid, interact with tissues and organs in complex ways to maintain homeostasis and facilitate essential physiological processes. Blood, for instance, transports oxygen, nutrients, hormones, and waste products throughout the body, interacting dynamically with cells and tissues to support metabolism and repair. Synovial fluid lubricates joints, reducing friction and enabling smooth movement, while cerebrospinal fluid cushions the brain and spinal cord, protecting them from mechanical shocks. These interactions are crucial for maintaining health and responding to physiological changes.
