Answers (1)

Spaceflight osteopenia:  It refers to the individual bone loss that occurs during spaceflight. There is concern that during the long-duration of space flights, excessive bone loss takes place, and the associated increase in serum calcium ion levels will interfere with the execution of mission tasks and it results in irreversible skeletal damage.

Ebullism:  It is the formation of gas bubbles in body fluids due to reduced environmental pressure, for example at high altitude due to the low atmospheric pressure water vapor in the body appears to boil and causing the skin to inflate like a balloon.
