The milk secreting cells of the mammary glands are cells of the alveoli. Capillary cells, alveolar epithelial type 1 cells, and alveolar epithelial type 2 cells make up the alveolus. Large, squamous epithelial cells known as type 1 cells occupy around 95% of the alveolar surface area. Surfactant is produced by type 2 cells, which also contribute to the preservation of lung fluid balance.
Mammary Gland
- All female mammals have a mammary gland that is capable of producing milk.
- The mammary glands are paired organs located in the breasts, which also contain varying amounts of fat and glandular tissue.
- Each breast’s glandular tissue is divided into 15–20 mammary lobes, each of which contains alveoli, and cell clusters.
- Milk is secreted by alveolar cells and is then stored in the alveolar lumens.
- Alveoli that enter mammary tubules do so.
- Each lobe’s tubules combine to form a mammary duct.
- A larger mammary ampulla is created when several mammary ducts come together. This ampulla is connected to the lactiferous duct, which is where milk is expelled.
- Consequently, alveoli are made up of cells that secrete milk.

Alveolar cells make up the mammary glands’ milk-secreting glands. The alveolus is composed of capillary cells, alveolar epithelial type 1 cells, and alveolar epithelial type 2 cells. About 95% of the surface area of the alveolus is occupied by large, squamous epithelial cells called type 1 cells. Type 2 cells, which also help to maintain the fluid balance in the lungs, produce surfactant.
