Question

Sudorific glands are characteristic features of
(a)Birds
(b)Mammals
(c)Poisonous snake
(d)Toads

Answer 1

Hint: Sudorific or sweat glands perform the function of excretion as well as cooling of the body. These glands carry out diaphoresis or sweating as the result of thermoregulation by the hypothalamus.

Complete answer:
Sweat glands of mammals are known as Sudorific glands. They are exocrine glands and serve the purpose of excretion as well as temperature control. Other animals who aren't mammals do not have these glands.

Additional Information: Let us know more about the Sudorific glands of mammals:
-These are also known as sweat glands or sudoriferous or sudoriferous glands.
-These are small tubular-shaped exocrine glands found in the skin which secretes sweat by way of a duct.
-These are of two types- Eccrine glands which are found all over the human body and secrete a water-based liquid that cools down the humans and Apocrine glands which are limited to the armpits and perianal areas and are sole sweat glands in hoofed animals like camels, donkeys, horses, and cattle.
-These consist of a secretory unit, and a duct that carries the sweat away. The unit consists of a base rolled into a glomerulus.
-In the case of humans, these glands are concentrated in the palm of hands and soles, on the head, and distributed less in the trunk and the extremities.
-These glands hold a very important role in excretion as the sweat contains excretory chemicals like urea and ammonia and carry these out of the body.
-The action of these glands depends on age and gender as well. In the case of kids or infants, most of the glands are inactive and get active as the person gets adulthood. During puberty, they produce more sweat. Men have more active glands than women.
So, the correct answer is "mammals".

Note: Sweating is done by the Sudorific glands which is an involuntary action caused by the autonomic nervous system and is a part of thermoregulation in the body. It commonly occurs in the face, armpits, palms of hands, and soles of feet. The thermoregulation is maintained by the hypothalamus which also controls sweating actions. The secretion of these glands i.e. the sweat exits via pores in the skin and evaporates into the atmosphere.
