What law states that the quantity of nitrogen and oxygen that dissolves in the body’s tissues when 33 feet below the surface, will then be two times that at sea level?
  1. Starling’s law
  2. David’s law
  3. Pram’s law
  4. Henry’s law
Explanation
Answer - D - Henry’s law states that the quantity of nitrogen and oxygen that dissolves in the body’s tissues when 33 feet below the surface will then be two times that at sea level. Since the body is made up primarily of liquid, gases that are inhaled will be dissolved in the body in proportion to the partial pressure of each breath. The body uses oxygen, but it does not use nitrogen. Therefore, the primary gas dissolved in the body is nitrogen because it is inert and not used by the body.
