A body cavity is any space or compartment, or potential space, in an animal body. Cavities accommodate organs and other structures; cavities as potential spaces contain fluid. The two largest human body cavities are the ventral body cavity, and the dorsal body cavity. In the dorsal body cavity the brain and spinal cord are located.
Human anatomy. This article contains a list of organs in the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming a more common practice [ 1][ 2] ); however, there is no universal standard definition of what constitutes an organ, and some ...
Lymph (from Latin lympha 'water') [ 1] is the fluid that flows through the lymphatic system, a system composed of lymph vessels (channels) and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to be recirculated.

The vitreous body ( vitreous meaning "glass-like"; from Latin vitreus 'glassy', from vitrum 'glass' and -eus) is the clear gel that fills the space between the lens and the retina of the eyeball (the vitreous chamber) in humans and other vertebrates.
The extracellular fluid compartment is further subdivided into the interstitial fluid and the intravascular fluid compartments. Body fluids, bodily fluids, or biofluids, sometimes body liquids, are liquids within the body of an organism. [ 1] In lean healthy adult men, the total body water is about 60% (60–67%) of the total body weight; it is ...
History of anatomy. Dissection of a cadaver, 15th-century painting.
