What else can I help you with?
With which disorder do the alveolar walls lose their elasticity become over-inflated and eventually rupture?
This condition is known as emphysema. It is characterized by damage to the alveoli in the lungs, leading to a loss of elasticity in the alveolar walls. Over time, this can result in the alveoli becoming over-inflated and eventually rupturing, causing difficulty breathing and other respiratory issues.
How do alveolar and capillaries work together to provide the muscles with oxygen?
as it moves through blood vessels capillaries in the alveoli walls, your blood takes oxygen from the alveoli and gives off carbon dioxide to the alveoli
What are the small holes in the walls of the inter alveolar septa?
The small holes in the walls of the inter alveolar septa are called pores of Kohn. They allow for gas exchange between adjacent alveoli, helping to equalize pressure and promote more efficient oxygen and carbon dioxide diffusion.
What is the function of simple squamous epithelium of the alveoli?
The alveoli is just one cell layer thick so that diffusion of gasses between the capillaries and the alveoli is easy. Simple squamous epithelium are found in the capillary walls and the alveolar walls. They are thin so diffusion is easy.
Name the slippy secretion that keep the alveolar walls from sticking together?
Pulmany Surfactants. This is accomplished by lowering the surface tension in the aveoli. When the surface tension in the aveoli is decreased it allows for easier reinhilation of the aveoli because there is less work required to do reinflate them.
What is the medical term meaning hyperinflation of air sacs with destruction of alveolar walls?
Emphysema or Pulmonay emphysema

What is the structure of respiratory membrane?
The respiratory membrane is formed by a combination of the walls of alveoli and walls of capillaries. It consists of type 1 alveolar cells, a basement membrane, capillary endothelium, alveolar epithelium and macrophages.
What is the destruction of alveoli walls?
The destruction of alveoli walls refers to the damage or breakdown of the tiny air sacs in the lungs, which are essential for gas exchange. This condition is often associated with chronic obstructive pulmonary disease (COPD), particularly emphysema, where the elasticity of the alveoli is lost, leading to reduced oxygen absorption and difficulty in breathing. As the alveolar walls deteriorate, the surface area for gas exchange decreases, resulting in impaired lung function and respiratory distress. This destruction can be caused by factors such as smoking, long-term exposure to pollutants, and genetic predispositions.
What is the loss of alveolar surface area called?
The loss of alveolar surface area is referred to as "alveolar destruction" or "alveolar collapse." This condition can occur in various respiratory diseases, such as emphysema, where the walls of the alveoli are damaged, leading to a reduction in gas exchange efficiency. This loss impairs oxygen uptake and carbon dioxide removal, contributing to respiratory complications.
Where does gas exchange of carbon dioxide and oxygen happen?
Gas exchange of carbon dioxide and oxygen takes place in the alveoli of the lungs. Oxygen from inhaled air enters the bloodstream through the alveolar walls, while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled.
Why does oxygen and carbon dioxide move from the alveoli into the blood stream?
Oxygen moves from the alveoli into the bloodstream through diffusion, where it crosses the thin walls of the alveoli and capillaries. Similarly, carbon dioxide moves from the bloodstream into the alveoli for removal when blood with high levels of carbon dioxide comes into contact with alveolar air with lower levels of carbon dioxide.
Describe the structure of a terminal bronchiole and its alveolar sac?
terminal brobchiole is formed as a result of division of respiratory bronchiole. It is extremely thin and end up into alveolar sac ALVEOLAR SAC THESE ARE SMALL SACS WITH 8 TO 10 SACCULES CALLES ALVEOLI. IT HAS CENTRAL AIR PASSAGE. THESE ALVEOLI SERVE AS RESPIRATORY MEMBRANE AND HELP IN EXCHANGE OF GASES
What makes it difficult to inflate the alveolar space?
The alveoli have a high surface tension due to a liquid film that covers their walls, making it difficult to inflate them. Additionally, the presence of surfactant helps to reduce surface tension in the alveoli, making inflation easier. When the alveoli are collapsed or have decreased compliance, it can also make it challenging to inflate them.
Why diffusion of gases occurs in the alveolar region only?
Diffusion of gases occurs in the alveolar region only because this is where the thin walls of the alveoli allow for efficient exchange of oxygen and carbon dioxide between the air in the lungs and the blood in the capillaries. The high surface area and close proximity of the alveoli to the capillaries facilitate rapid diffusion of gases.
