The glands in the skin associated with leaving fingerprints are called eccrine glands. These glands produce a watery sweat that helps regulate body temperature and can leave moisture on the skin's surface, aiding in the formation of fingerprints. The unique patterns of ridges and valleys on the fingertips, known as friction ridges, are what create the distinct fingerprint impressions.

What is a gland found on your skin?
Sweat gland.
Do the people have cells in ther fingerprints?
Yes, fingerprints are made up of ridges and valleys formed by the arrangement of skin cells. The ridges contain sweat pores that emit oils and sweat, leaving behind unique patterns that make up a person's fingerprint.
