Question

Which sequence correctly traces the milk pathway from alveoli to nipple?

Options

• Alveoli → Mammary Tubules → Mammary Duct → Mammary Ampulla → Lactiferous Duct → Nipple

• Alveoli → Lactiferous Duct → Mammary Tubules → Mammary Ampulla → Mammary Duct → Nipple

• Alveoli → Mammary Duct → Mammary Tubules → Lactiferous Duct → Mammary Ampulla → Nipple

• Alveoli → Mammary Ampulla → Mammary Tubules → Mammary Duct → Lactiferous Duct → Nipple

Answer 1

Alveoli open into the mammary tubules. Tubules of each lobe join to form the mammary duct. Several ducts join to form the wider mammary ampulla. The ampulla connects to the lactiferous duct, which opens at the nipple.
