If this occurs too much, you die of dehydration, since a certain tissue water concentration is necessary for cells to do their chemistry and keep you alive. You will die faster if you drink just sea water than if you drink nothing at all. The skeleton consists of the hard parts of the body against which muscles act. Not all organisms have skeletons. Bone is living tissue, and bleeds when broken.
Birds have very airy bones, large animals have very dense bone.
Cartilage is a flexible, smooth supporting tissue, and the main component of the nose and ears, as well as joining the ribs to the breastbone. The tissues which bind bones to other bones at joints are called ligaments, the tissues which bind muscles to bones are called tendons. Bone heals faster than ligaments and tendons, and is stronger after a break than before. Ligaments and tendons heal more slowly, and usually aren't as strong after being severely stretched or torn as they were before. Tendons are easy to see on the underside of the wrist, and on the back of the hand.
