Question 2

People who live in a Scandinavian country-Norway, Sweden, or Finland-may have bigger problems with porous bone or osteoporosis. Remember that the extreme northern and southern latitudes of the earth get less direct sun. How is porous bone in any way related to sun exposure?

Accepted Answer

Less sun exposure means less vitamin D₃production in the skin. Less vitamin D₃ means there is less calcitriol hormone, which is necessary for calcium absorption in the small intestine. This causes blood calcium levels to drop. Less deposition of calcium in bone results in porous bone, which produces weak bone that can break easily.
