Interfering with the cohesiveness of water molecules, thereby reducing the surface tension of alveolar fluid.
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.
They produce surfactant, a substance that reduces surface tension. Alveoli are very small, only 80 nanometers wide, and are flat. Therefore they have a tendency to curl up. The surfactant reduces this tendency, hence keeps the alveoli from collapsing.
Type 2 alveolar cells secrete surfactant, a mixture of lipids and proteins that reduces surface tension in the alveoli, preventing them from collapsing. This helps maintain the elasticity of the alveoli and promotes efficient gas exchange in the lungs.
Type 2 alveoli cells secrete surfactant, which helps to reduce surface tension in the alveoli. This allows for easier expansion of the alveoli during inhalation and prevents them from collapsing during exhalation, promoting efficient gas exchange.
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, a substance produced by type II alveolar cells in the lungs, reduces the surface tension of fluid in the alveoli. This helps to prevent the collapse of alveoli during expiration and facilitates the exchange of gases in the lungs.
The fatty molecule on the respiratory membrane is called a surfactant. Surfactant helps reduce the surface tension of the fluid lining the alveoli in the lungs, allowing for easier expansion and preventing the alveoli from collapsing during exhalation.
Septal cells, also known as Clara cells, are found in the respiratory bronchioles of the lungs. They produce surfactant, a fluid that helps reduce surface tension in the air sacs (alveoli) of the lungs, preventing them from collapsing. Septal cells also play a role in protecting the airways from foreign particles and toxins.
The structure of the lungs, which are surrounded by a lining called the pleura, helps to keep them inflated. The pleural pressure is lower than the pressure inside the alveoli, creating a partial vacuum that prevents the lungs from collapsing. Additionally, the presence of surfactant in the alveoli reduces surface tension, helping to maintain lung expansion.
Pneumocyte. There are two types: Type I cells make up the lining of the air sacks (alveoli) in the lung, type II cells produce a slick liquid called surfactant that helps coat the alveoli and keep them from collapsing when we exhale.
The lungs do not normally collapse during expiration because they are held open by the negative pressure in the pleural space, created by the pulling force of the diaphragm and intercostal muscles. This negative pressure helps maintain the alveoli's shape and prevents them from collapsing completely. Additionally, the presence of surfactant in the alveoli helps reduce surface tension and keeps the alveoli inflated.
Type II alveolar cells in the lungs secrete surfactant, a substance that helps reduce surface tension in the alveoli to prevent their collapse during exhalation. This surfactant is crucial for maintaining optimal lung function by promoting proper gas exchange.
