Answer: 3 The inner linings provide protection against germs and injuries.
Explanation:
The Inner Linings of the body are called the Epithelial tissue and they form the outer lining of internal organs and blood vessels as well as the internal cavities in most internal organs.
With these tissues surrounding the organs, the organs are protected against injury as they instead absorb the impact of the injury first. The lining also prevents invasion by germs into the organs and blood vessels by acting as a barrier.
