Acidity in human sweat is an example of _____. Acidity in human sweat is an example of _____. acquired immunity adaptive immunit
Tpy6a [65]

Acidity in human sweat is an example of<u> </u><u>innate immunity</u>

Explanation:

Sweat arising from human skin is acidic in nature with a pH ranging between 4.5 to 7.

As part of innate immunity, the skin acts both as a physical barrier and chemical shield.

As part of chemical shield, the skin’s sebaceous glands present on the skin produces an oily substance called sebum which contains free fatty acids. Further, hair follicles on skin releases lactic acid which bind with the amino acids of the proteins present on the keratinized layers of skin. The acidity of the sweat is due to the combined action of free fatty acids, lactic acid and the amino acids present on the skin.

This natural acidic nature of skin creates a hostile acidic environment to pathogens which prevents their entry into the body.
