Final answer:
The statement is true; mammary glands in both males and females are modified sweat glands and are a part of the integumentary system.
Step-by-step explanation:
The statement that mammary glands in males and females are modified sweat glands that are actually part of the integumentary system is true. Mammary glands are indeed part of the integumentary system and are believed to have evolved from sebaceous or eccrine glands. Mammalian skin includes a number of secretory glands with varying functions. For instance, sebaceous glands produce sebum for water resistance and lubrication, whereas sudoriferous glands (sweat glands) aid in thermoregulation. Mammary glands, which both male and female eutherians (and some male marsupials) possess, produce milk that is vital for nourishing newborns.
During lactation, the structure of the female breast becomes more complex. It includes numerous milk-secreting alveoli and lactiferous ducts that drain the milk to the nipples. In both the function and structure of the mammary glands, there are clear indications of their origin as modified sweat glands, adapted over time to their role in the nourishment of young mammals.
