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 fluid lining the inner alveolar membrane is called surfactant. It helps reduce the surface tension in the alveoli, which prevents them from collapsing in on themselves every time we exhale.
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.

The fluid that lines the alveoli contains a substance that reduces surface tension known as?
surfactant
True or false the fluid coating the alveoli that reduces surface tension is called surfactant?
True; produced by Type II pneumocytes

The fluid lining the inner alveolar membrane is called surfactant. It helps reduce the surface tension in the alveoli, which prevents them from collapsing in on themselves every time we exhale.
Surfactant helps to prevent the alveoli from collapsing by what?
Interfering with the cohesiveness of water molecules, thereby reducing the surface tension of alveolar fluid.
What fluid is produced by produced by type II alveoli cells?
Type II alveolar cells, also known as pneumocytes, produce pulmonary surfactant. This fluid is a complex mixture of lipids and proteins that reduces surface tension in the alveoli, preventing their collapse during exhalation and facilitating gas exchange. Surfactant plays a crucial role in maintaining lung stability and efficiency in breathing.
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.
How does surfactant affect the total air flow into lungs?
Surfactant is similar to a detergent, it keeps the fluid coating the lining of the alveoli from creating surface tension. This allows the alveoli to expand without hindrance, and allows greater air flow.
Which fluid is filled in foetus lungs at 8th month?
At around the 8th month of gestation, the lungs of the fetus are filled with a fluid called amniotic fluid. This fluid is crucial for lung development and helps prepare the fetus for breathing air after birth. The lungs also begin producing surfactant, a substance that reduces surface tension and prevents the alveoli from collapsing, which is essential for proper breathing once the baby is born.
What causes intra alveolar-surface tension?
Intra-alveolar surface tension is caused by the presence of fluid lining the alveoli, mainly composed of surfactant molecules. Surfactant helps reduce surface tension by lowering the cohesive forces between water molecules, preventing alveolar collapse during exhalation and allowing for efficient gas exchange in the lungs.
