How does elastic recoil function in breathing?
During exhalation, elastic recoil is responsible for the passive recoil of the lungs and chest wall. As the diaphragm and external intercostal muscles relax, the elastic fibers in the lungs and chest wall recoil, pushing air out of the lungs. This process helps to expel air from the lungs and facilitates the breathing cycle.
What is the force responsible for normal expiration?
The force responsible for normal expiration is passive recoil of the lungs and chest wall. As the diaphragm and external intercostal muscles relax, the elastic recoil of these structures causes the lungs to decrease in volume, leading to expiration.
What is elastic recoil?
Elastic recoil refers to the ability of a stretched or deformed material to return to its original shape or size once the deforming force is removed. This phenomenon is commonly seen in elastic materials like rubber bands, blood vessels, and the lungs, where they can stretch and recoil back to their original state. In the case of the lungs, elastic recoil helps in exhaling air by effectively reducing the lung volume.
What is the medical term meaning The tendency of the thorax and lungs to return to the pre-inspiration volume?
Elastic recoil
Name of surfactant that breaks surface tension in the lungs?
Am pretty sure its called the pulmonary surfactant that's produced from the lungs
What is the function of elastic fibers in the trachea?
Longitudinal elastic fibers enable the trachea to stretch and descend with the roots of the lungs during inspiration.
Are the lungs muscular or elastic?
It is the natural elasticity of the lungs that allows us to exhale.
How effective is surfactant therapy?
Normally surfactant replacement therapy keeps the infant alive until the lungs start producing their own surfactant.
What is the principal driving force for exhalation at rest?
During exhalation at rest, the principal driving force is passive elastic recoil of the lungs and chest wall. As the diaphragm relaxes and the external intercostal muscles relax, the lungs passively recoil to their resting size, which pushes air out of the lungs. This process does not require active muscle contraction.
What is the name of the liquid found in the lining of the lungs?
Surfactant
Phospholipid that allows the lungs to expand with ease?
Surfactant
Breathing properly requires the presence of what compound that affects surface tension of alveoli in the lungs?
The correct answer is Surfactant
