What is the role of mammary glands?

• A. Produce milk
• B. Produce bile
• C. Store nutrients
• D. Excrete urine

Answer: (A)

Mammary glands are specialized exocrine glands whose main job is to produce milk to feed a newborn. Milk is made by the alveolar cells inside the glands and travels through a network of ducts to be released during nursing. Hormones like prolactin drive milk production, while oxytocin causes the milk to be ejected from the glands when the baby nurses. In contrast, bile is produced by the liver and stored in the gallbladder, nutrients are stored mainly in the liver and adipose tissue, and urine is excreted by the kidneys. So the role that fits best is producing milk.
