A study undertaken in 1947 was the first time anatomists attempted to understand it. Considering collagen drinks and supplements? Knuckle "cracking" has not been shown to be harmful or beneficial. If this transition is rapid, there will not be enough time for the nitrogen to escape from the body. Helium is less soluble in the blood stream, providing a smaller threat to divers when they come up to the surface of the ocean. . The solubility of a gas is the ability for the gas to dissolve in a solvent (in our case, blood, which although it contains organic components is essentially an aqueous solution).
