Sweating and thermoregulation in hippos

Splet01. jan. 2024 · Sweating as a heat loss thermoeffector is indispensable for proper thermoregulation. Sweat is produced by approximately 2 million eccrine glands distributed over the body surface. These glands are stimulated by the release of acetylcholine from sudomotor nerves in response to increases in skin and/or internal body temperatures. In … Splet22. jan. 2024 · Sweating is a method by which the body regulates its internal temperature and is known as thermoregulation. Sweat glands secrete a watery substance through the pores on our skin. These beads of perspiration soon evaporate off the skin, taking the heat with them. There are two types of sweat glands, namely eccrine and apocrine.
