Sweat isn't so much part of the 'immune' system, as the 'defense' system.

Your body has three lines of defense

The first is the skin

The second is sweat, hair and white blood cells.

Sweat helps keep you cool, but when you get hotter, your skin pores open up more, and sweat on top of these prevents alot of airborne bacteria getting into your bloodstream via that.

If you wanted to know, the third is your bodies antibodies!
