Question

Arrange the following parts in human Mammary gland, traversing the route of milk ejection.
A. Mammary duct
B. Lactiferous duct
C. Mammary alveolus
D. Ampulla
E. Mammary tubule
Choose the correct answer from the options given below:

• A. D → C → E → A → B
• B. C → E → B → A → D
• C. C → E → A → D → B
• D. A → C → E → D → B

Answer 1

The Correct Option is C

The question requires us to arrange the parts of the human mammary gland in the order that milk follows during ejection. The correct sequence of milk flow from its production to ejection is as follows:

1. Mammary Alveolus (C): Milk production begins in the mammary alveoli, which are small glandular sacs. The cells lining these alveoli synthesize milk.
2. Mammary Tubule (E): The milk produced in the alveoli flows into small ducts called mammary tubules.
3. Mammary Duct (A): These tubules converge into larger ducts known as mammary ducts.
4. Ampulla (D): The mammary ducts widen into a structure called the ampulla. The ampulla acts as a reservoir where milk is stored temporarily.
5. Lactiferous Duct (B): Finally, milk is transported through the lactiferous ducts, which lead to the nipple, enabling ejection of milk.

The correct order based on the above explanation is:
C → E → A → D → B

Thus, the correct answer matches the option: C → E → A → D → B
