Certified Breastfeeding Counselor Practice Exam 2025 – Comprehensive Test Prep

Question: 1 / 400

What is an Alveolus?

Small cavity where milk is produced and stored

An alveolus is a small cavity where milk is produced and stored within the breast. During lactation, alveoli play a crucial role in the breastfeeding process by secreting and storing milk until it is ejected through the ducts to the nipple for the infant to feed. This anatomical structure is essential for milk production and regulation in breastfeeding mothers.

Option B, a large duct connecting lobules, is not correct because alveoli are the structures responsible for producing milk, whereas ducts are responsible for carrying milk from alveoli to the nipple.

Option C, a newborn baby sling, is not relevant to the anatomy or physiology of breastfeeding.

Option D, an accessory organ aiding digestion, is not correct as alveoli are specific structures within the breast related to milk production and not involved in aiding digestion.
