Sweat pores: this photo is a coloured scanning electron micrograph (SEM) of sweat (light blue) produced by sweat pores on skin from a human hand.

Sweat is released onto the surface of the skin from glands below the surface. The sweat evaporates, and this cools the body by carrying away heat. The surrounding areas shows the dead cells making up the surface layer of the skin, the stratum corneum. Magnification: x50 when printed 10cm wide.

False-colour scanning electron micrograph of skin from the palm of the hand of a 30 year old man. The skin here is neatly arranged in ridges. Sweat pores are seen as miniature craters along the ridges. The cells forming the external surface of the skin, or epidermis, have been flattened & hardened by deposition within them of the fibrous protein keratin. This tough, dead layer of cells is shed continuously & is replaced by new, maturing cells which take a month to migrate from the base of the epidermis.
