👉 The six fluids in the human body are blood, lymph, interstitial fluid, cerebrospinal fluid (CSF), synovial fluid, and pleural fluid. Blood is a complex fluid composed of plasma and cells, transporting oxygen, nutrients, hormones, and waste products throughout the body. Lymph is a clear fluid that circulates through the lymphatic system, aiding in immune function by carrying white blood cells and removing toxins. Interstitial fluid fills the spaces between cells, facilitating nutrient exchange and waste removal. Cerebrospinal fluid protects the brain and spinal cord by cushioning them and maintaining a stable chemical environment. Synovial fluid lubricates joints, reducing friction during movement. Lastly, pleural fluid lines the lungs and chest cavity, ensuring smooth breathing by preventing lung tissue from sticking to the pleura during expansion and contraction.
