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.
How do seed coats open?
The sun dries and cracks them open
What is the word for the spring that they put inside the coronary to keep the blood flowing smoothly?
The device placed inside blood vessels to keep them open is called a stent.
Is the liquid inside a glow stick safe for children?
They are safe as long as the chemicals stay inside the plastic cover. Do not open or cut the glow sticks keep the chemicals inside where they can not be ingested.
What substance helps maintain inflation of the alveoli so that they do not collapse on themselves during inspiration?
A product of the lung tissues called surfactant keeps the tiny alveoli open.
Alveoli have neither smooth muscle or mucous secreting cells?
That is correct. Alveoli only contain only two types of cells: Type I cells that are like thin sheets and make up the actually wall of the alveoli, and Type II cells that secrete a substance called surfactant that helps to hold the alveoli open. There can also be some macrophages present in the alveoli to destroy invading bacteria.
Why is 5 months premature baby safer than 6 months premature baby?
This is not true as surfactant, which helps to keep the lungs open and prevents the alveoli from sticking together, is not formed until 37 weeks gestation.
What is wrong when a door is open but the lock mechanism won't unlock?

Try checking for a child lock. If it's on, it'll keep the door from being able to be opened from the inside. Happens in our car all the time.
What cause alveolus to stick together?
Alveoli can stick together due to surfactant deficiency, which reduces the surface tension that helps keep the alveoli open. In conditions such as acute respiratory distress syndrome (ARDS), pneumonia, or pulmonary fibrosis, the lack of surfactant can cause alveolar collapse and adhesion. This can lead to difficulty in breathing and impaired gas exchange in the lungs.
