The chemical compound that prevents the lungs from collapsing is called surfactant. Surfactant is a mixture of lipids and proteins produced by the cells in the alveoli (air sacs) of the lungs. It reduces surface tension in the alveoli, allowing them to remain open and facilitating the exchange of gases during breathing. This is particularly crucial in newborns, as insufficient surfactant can lead to respiratory distress syndrome.
What else can I help you with?
Does the pleural membrane hold the lungs air tight?
Yes, the pleural membrane helps create a seal around the lungs, which assists in maintaining their inflation by creating negative pressure in the pleural cavity. This negative pressure allows the lungs to expand during inhalation and prevents them from collapsing.
Which structure is lined with rings of cartilage?
The trachea, or windpipe, is the structure lined with rings of cartilage. These C-shaped cartilaginous rings provide support and maintain the airway's openness while allowing flexibility during breathing. The cartilage prevents the trachea from collapsing, ensuring that air can freely flow to and from the lungs.
What do septal cells do?
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.

What is the valve that prevents blood returning to the right ventricle after it pumps?
The aortic semilunar valve prevents backflow of blood from the aorta to the left ventricle.The aortic valve prevents backflow of blood from the aorta to the left ventricle of the heart.aortic valve
What is the protein fat compound that creates surface tension and keeps the walls of the alveoli from collapsing?
The compound is called surfactant, which is a mixture of lipids and proteins. Surfactant reduces surface tension in the alveoli, preventing them from collapsing and allowing for efficient gas exchange in the lungs.
Why is the trachea hard?
The trachea is bolstered by cartilage tissue, which prevents it from collapsing.
What keeps the lungs from collapsing when the airways are open to the atmosphere?
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.
What is the fluid that prevents alveoli from collapsing?
The fluid that prevents alveoli from collapsing is called surfactant. Surfactant is a lipoprotein complex produced by the type II alveolar cells in the lungs. It reduces surface tension within the alveoli, allowing them to remain open during exhalation and facilitating efficient gas exchange. Without surfactant, the alveoli would collapse, making breathing difficult.
What prevents food or liquids from getting into lungs?
What prevents food from getting into the lungs is an Aorta.
The prevents food or liquids from getting into the lungs.?
What prevents food from getting into the lungs is an Aorta.
What are the advantages of a whales lungs collapsing when diving?
don't surface as much
What is The volume of air that remains in the lungs after a complete expiration called?
The volume of air that remains in the lungs after a complete expiration is called the residual volume. This volume is important as it prevents the lungs from collapsing and allows for continuous gas exchange even between breaths. Residual volume varies among individuals and is influenced by factors such as age, gender, and lung health.
Does the pleural membrane hold the lungs air tight?
Yes, the pleural membrane helps create a seal around the lungs, which assists in maintaining their inflation by creating negative pressure in the pleural cavity. This negative pressure allows the lungs to expand during inhalation and prevents them from collapsing.
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 is the amount of air the remains in the lungs at the end of normal expiration approx. 2300mls?
The amount of air that remains in the lungs at the end of normal expiration is known as the residual volume, which is approximately 2300 mL. This volume is essential as it prevents the lungs from collapsing and allows for continuous gas exchange, even between breaths. Residual volume is a key component of lung capacity measurements, influencing overall respiratory health.
What is the function of residual volume?
The function of residual volume is to keep enough pressure in the lungs to keep them from collapsing.
