Question

lets check what youve remembered from that quick overview. what are the basic functions of skin? a) protect and insulate the body and its organs, prevent water and heat loss, and synthesize proteins and vitamin d b) prevent water and heat loss, remove the majority of water and waste fluids from the body, stabilize blood circulation c) remove the majority of water and waste fluids from the body, synthesize vitamins d and a, prevent water and heat loss d) synthesize natural antimicrobials, protect and insulate the body, regulate the temperature of internal organs

Explanation:

The skin protects and insulates the body and its organs, prevents water and heat loss, and synthesizes vitamin D. It does not synthesize proteins, remove the majority of water and waste fluids (that's mainly the kidneys' job), or synthesize vitamins A and D together as described in incorrect options. It also doesn't regulate the temperature of internal organs in the way stated in option d.

Answer:

a) Protect and insulate the body and its organs, prevent water and heat loss, and synthesize vitamin D
