Can you explain this answer?

Question

Answer

The mammary alveoli open into mammary tubules. The tubules of each lobe join to form a mammary duct, several mammary ducts join to form a wider mammary ampulla which is connected to lactiferous duct through which milk is sucked out.

Answer

The correct path of flow of milk in the mammary glands of a lactating human female is:

Mammary alveoli ⟶ Mammary tubule ⟶ Mammary duct ⟶ Lactiferous duct

Explanation:

Mammary alveoli:
- The mammary gland is composed of multiple lobes, each containing smaller lobules.
- Each lobule consists of clusters of grape-like structures called mammary alveoli.
- These alveoli are the functional units responsible for milk production.

Mammary tubule:
- Milk is produced within the mammary alveoli by secretory cells.
- The secretory cells release milk into small ducts called mammary tubules.
- These tubules are connected to the alveoli and serve as conduits for milk.

Mammary duct:
- The mammary tubules merge to form larger ducts called mammary ducts.
- These ducts transport the milk towards the nipple.

Lactiferous duct:
- The mammary ducts converge and form larger milk-carrying ducts called lactiferous ducts.
- The lactiferous ducts transport the milk towards the nipple, where it can be expelled through breastfeeding.

The correct path of the flow of milk in the mammary glands is from the mammary alveoli, through the mammary tubules, mammary ducts, and finally, the lactiferous ducts.

This pathway ensures that milk produced in the mammary alveoli is efficiently transported towards the nipple for breastfeeding.
