What are dust cells?
Dust cells are also known as alveolar macrophages. They are found on inner surfaces of lung alveoli. They eat up pathogens or any foreign particles there.
What is also known as the intra-alveolar pressure?
Intra-alveolar pressure is also known as the machinal chain.
What is also known as the intra alveolar pressure?
Intra-alveolar pressure is also known as the machinal chain.
How does the body remove microorganisms that make their way into the respiratory zone?
alveolar macrophages crawl freely along internal alveolar surfaces
What would happen if a dust particle made it to the alveoli?
The alveolar macrophages would phagocytize(eat) it.

What has the author Isabel Leal Barbosa written?

What is the function of alveolar macrophage in the lungs?
function of alveolar macrophagesThe function of alveolar macrophage in the lungs is to remove dust particles and other debris from alveolar spaces. -SheshiAveolar macrophages work to break up surfactanct in the aveoli which exists to decrease surface tension in the lungs. If there is a disorder where the macrophage does not function correctly, such as in PAP, the surfactant will not be broken up and decreased ventilation will occur resulting in less oxygen delivery.
What removes debris from the air?
Alveolar macro-phages uptake debris which reach the alvoli. they are derived from circulating monocytes as well as mitotic division of already present macrophages.
What has the author Christopher Gary Compeau written?
Christopher Gary Compeau has written: 'Endotoxin-stimulated alveolar macrophages impair distal lung epithelial permeability and ion transport'
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.
How do macrophages recognize infectious agents such as bacteria?
When antibodies bind to the epitopes of an antigen(bacteria) via antigen receptors, the antibodies present the bacteria to a macrophages in a form that they recognize the foreign substance and engulf them. This antibody-antigen "team work" is also known as opsonization
