Which systems interacts with the integumentary system when skin is acting as a barrier to protect the body from pathogens

it is either c or d and i know for sure it is not a or b

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
