Alveolar ducts
Definition
Alveolar ducts are the small airway passages in the lungs that connect respiratory bronchioles to alveolar sacs. They play a crucial role in gas exchange by allowing air to reach the alveoli where oxygen and carbon dioxide are exchanged.
5 Must Know Facts For Your Next Test
- Alveolar ducts culminate in clusters of alveoli, which are essential for efficient gas exchange.
- Nutritional status can impact the integrity and function of alveolar ducts, affecting pulmonary health.
- Optimal levels of antioxidants from diet can protect alveolar duct linings from oxidative damage.
- Inflammation in the alveolar ducts can lead to compromised breathing efficiency and is influenced by dietary factors.
- Proper hydration is necessary to maintain mucosal lining health within alveolar ducts, facilitating better respiratory function.
