Final answer:
In the mammalian integument, the exocrine glands present include sweat glands for thermoregulation and sebaceous glands for lubricating the skin and hair. Thus, the correct answer is A) Sweat glands and sebaceous glands.
Step-by-step explanation:
The exocrine glands present in the integument, or skin, of mammals include the sweat glands and sebaceous glands. The sweat glands, also known as sudoriferous glands, are involved in thermoregulation, aiding in temperature control through the process of evaporative cooling. Sebaceous glands produce a substance called sebum, which lubricates and waterproofs the skin and hair.
Mucous glands are not typically located within the integumentary system of mammals. They are commonly found in the mucosal linings of various organs such as the respiratory and digestive tracts. Similarly, mammary glands, while part of the integumentary system, have a specific role in feeding offspring and are not generally described as a part of the answer to this specific question.
Therefore, the correct answer to which exocrine glands are present in the integument is A) Sweat glands and sebaceous glands.
