Alveolarization

Definition

Alveolarization is the process of forming alveoli, which are tiny air sacs in the lungs where gas exchange occurs. Proper alveolarization is crucial for effective respiratory function and overall pulmonary health.

5 Must Know Facts For Your Next Test

1. Alveolarization predominantly occurs during late fetal development and continues into early childhood.
2. Nutritional deficiencies, particularly in essential fatty acids and proteins, can impair alveolarization.
3. Vitamin A plays a crucial role in alveolar development and repair.
4. Adequate maternal nutrition during pregnancy is vital for proper alveolarization in the fetus.
5. Impaired alveolarization can lead to chronic lung conditions such as bronchopulmonary dysplasia.
