Question

When an infant suckles at its mother's breast, milk moves through the breast structures in what order

Answer 1

When an infant suckles at its mother's breast, milk moves through the breast structures in the order

Acinus - lactiferous duct - lactiferous sinus - nipple

When an infant suckles, milk is secreted from lactocytes into the alveoli (acinus). The milk is then squeezed from the alveoli so it can drain into the lactiferous ducts, milk drains from lactiferous ducts into lactiferous sinuses, and discharge through the nipple pores.

Hence, when an infant suckles at its mother's breast, milk moves through the breast structures in the order

Acinus - lactiferous duct - lactiferous sinus - nipple
