Answer :

Sweat is used for thermoregulation. As sweat is released onto the surface of the epidermis, heat from the body is conducted into the water. Water is a better conductor of heat than air is. As the sweat evaporates, the heat from the body dissipates into the environment.

Eccrine glands are sweat glands and maintains body temperature. In their absence body face difficulty in thermoregulation.

Further explanation

Sweat glands

They are coiled tubes of epidermal origin, though they lie in the layer of skin. Lumen or central space is surrounded by secretory cells. into which the secretion is extruded. Sweat glands can be of various types.

Function of sweat glands

They play a vital role in the regulation of body temperature. They secrete electrolytes and water from body through skin.

Types of sweat glands

  1. Eccrine glands
  2. Apocrine glands

Eccrine glands and their function

Eccrine glands are also called merocrine glands. They are the real sweat glands of the human body, found in all over the skin, with the most elevated thickness in palm and soles, at that point on the head, yet substantially less on the storage compartment and the limits. In different vertebrates, they are generally inadequate, being discovered for the most part on bare territories, for example, foot pads. They arrive at peak of advancement in people, where they may number 200–400/cm² of skin surface. They produce a reasonable, scentless substance, sweat, comprising principally of water.
