Explanation:

Question 25

The labia majora and minora are external female genital structures. Their role is to protect the urethral (urinary opening) and vaginal (reproductive opening) openings. Fallopian tubes are internal, ovaries are internal reproductive organs, and mammary glands are breast structures—none are protected by the labia.

Question 26

The vestibule is part of the female external genitalia. The urethral (urinary) and vaginal (reproductive) openings are in the vestibule, which is distinct from the anal (digestive) opening. This separation helps prevent contamination between the urinary/reproductive and digestive systems. Reducing friction, minimizing blood flow, or hormone regulation are not the primary reasons for their location in the vestibule.

Question 27

Mammary glands are specialized in females (and some males) for lactation. Their primary function is to produce milk to nourish infants. Regulating estrogen is not their main role (hormone regulation is more associated with ovaries/endocrine glands), storing nutrients is not a glandular function here, and protecting the ribcage is the role of the ribcage itself or surrounding muscles, not mammary glands.
