Answer 1

Answer:

The first line of defence is non-specific and aims to stop microbesfrom entering the body. The skin and mucous membranes act as a physical barrier preventing penetration by microbes. If the skinis cut then the blood produces a clot which seals the wound and prevents microbes from entering.
