Open Ended

Explain why

​Astronauts and Skeletal System

• Because astronauts lose as much as 1 - 2% of their bone mass per month in space (due to constant 0 g).

• It takes lots of time when back on earth to rebuild this bone mass.​

Multiple Choice

How does exercise actually help build a healthier skeletal system?

• It causes micro-fractures that trigger bone remodeling.
