What is the serous fluid reduces surface tension?
Surfactants, which are molecules that lower surface tension, can be found in serous fluid. These molecules help prevent alveoli in the lungs from collapsing by reducing the surface tension of the fluid lining the alveoli.
What cells secrete surfactant that reduces the tendency for pulmonary alveoli to collapse?
Type II alveolar cells in the lungs secrete surfactant, which is a specialized fluid that lowers surface tension in the alveoli. This reduces the tendency for the alveoli to collapse during exhalation and helps maintain the elasticity of the lungs for efficient gas exchange.
What is the fluid in the alveoli called?
The fluid in the alveoli of the lungs is called pulmonary surfactant. It helps to reduce surface tension and prevent the alveoli from collapsing, allowing for efficient gas exchange during respiration.
What is the function of the surface of fluid lining the alveolar?
The surface of fluid lining the alveoli, known as surfactant, helps to reduce surface tension and prevent alveolar collapse during exhalation. It also helps to maintain the elasticity of the lungs and promotes gas exchange by allowing the alveoli to remain open.
What would in surfactant absence?
In the absence of surfactants, the surface tension of the liquid would be higher. This can lead to poor wetting and spreading of the liquid on a surface, impacting processes like cleaning, emulsification, and foaming. Surfactants help lower the surface tension, allowing them to perform these functions effectively.
