Elastic recoil

Definition

Elastic recoil is the ability of the lungs to return to their original shape after being stretched or filled with air. This property is crucial for efficient breathing and maintaining proper pulmonary function.

5 Must Know Facts For Your Next Test

1. Elastic recoil is essential for passive exhalation, allowing air to be expelled from the lungs without active effort.
2. Loss of elastic recoil can result in conditions like emphysema, where it becomes difficult to exhale fully.
3. Adequate nutrition, particularly proteins and antioxidants, supports lung tissue health and elastic properties.
4. Collagen and elastin fibers are key components that provide the structural basis for lung elasticity.
5. Chronic inflammation and smoking can degrade these fibers, reducing lung elasticity and impairing respiratory function.
