Blood, Saliva, Cerebrospinal Fluid (CSF-Brain/Spine), Semen, Vaginal Secretions, Synovial fluid (Joints), Amniotic Fluid (Uterus), Any other fluid that contains blood, Body fluids that cannot be recognized.

CSF - A clear fluid that occupies space in and around the spinal cord and brain. Essentially the brain "floats" in it.

Synovial fluid -  A thick, stringy fluid found in the cavities of synovial joints. With its egg-like consistency ("synovial" partially derives from ovum, Latin for egg), synovial fluid reduces friction between the articular cartilage and other tissues in joints to lubricate and cushion them during movement.
