Final answer:
The statement regarding the presence of mammary glands in the breast is true. These glands are crucial in producing milk and feeding infants, with a structure consisting of 15 to 25 lobes and alveoli that secrete milk through the nipple.
Step-by-step explanation:
The statement, 'The mammary glands are located in the breast,' is true. Mammary glands are specialized structures within the breasts that produce milk to feed infants after birth. Each mammary gland consists of 15 to 25 lobes, with ducts that lead to the nipple. These lobes contain alveoli, which are clusters of milk-secreting cells. When a baby nurses, these alveoli produce milk that passes through the ducts, lactiferous sinuses, and onto the nipple pores to provide nutrient- and antibody-rich milk that aids in the infant's development and protection.
