Final answer:
The claim that most human sweat glands are apocrine is false. Eccrine sweat glands are the primary ones involved in body thermoregulation, and they are found throughout the entire skin surface.
Step-by-step explanation:
The statement that in humans, most of the sweat glands are apocrine glands is false. Sweating regulates body temperature through the action of eccrine sweat glands, which are abundant and distributed across almost the entire surface of the skin. These glands produce a hypotonic sweat that is mostly water, aiding in thermoregulation. Eccrine glands are particularly numerous on the palms of the hands, the soles of the feet, and the forehead. On the other hand, apocrine glands, which are associated with hair follicles in areas such as the armpits and genital regions, are larger than eccrine glands but less numerous. They secrete a thicker sweat that includes organic compounds contributing to body odor. Therefore, eccrine glands are the primary sweat glands involved in cooling the body.
