There are three major alveolar cell types in the alveolar wall (pneumocytes):
* Type I cells that form the structure of an alveolar wall
* Type II cells that secrete surfactant to lower the surface tension of water and allows the membrane to separate thereby increasing the capability to exchange gases.
* Type III cells that destroy foreign material, such as bacteria.
What else can I help you with?
What produces surfactant?
Surfactant is produced by the type II alveolar cells in the lungs. These cells secrete surfactant which helps lower surface tension in the alveoli, preventing collapse and facilitating gas exchange.
In which layer of the alveolar membrane are the cleanup cells located?
The cleanup cells, also known as alveolar macrophages, are located in the alveolar space within the alveolar membrane. They play a crucial role in clearing debris, bacteria, and other particles from the lungs to maintain respiratory health.
What are the three types of cells that do not undergo mitosis?
Nerve cells, Red blood cells and cells from cornea of the eye balls.
Name 3 types of white blood cells?
There are several types of white blood cells (leukocytes.) The 3 main groups are granulocytes, monocytes, and lymphocytes. There are 3 types of granulocytes; neutrophils, eosinophils, and basophils. There are 2 main types of lymphocytes; B cells and T cells. There are 4 types of T cells; cytotoxic T cells, helper T cells, suppressor T cells, and natural killer cells.
List three types of body cells that must be replaced frequently?
Muscle cells,Skin cells, and white blood cells.
What it the alveolars lined with?
The alveoli, which are tiny air sacs in the lungs, are lined with a thin layer of epithelial cells called alveolar epithelium. This lining consists primarily of two types of cells: type I alveolar cells, which facilitate gas exchange, and type II alveolar cells, which produce surfactant to reduce surface tension and prevent alveolar collapse. The alveolar walls also contain a network of capillaries that enable the exchange of oxygen and carbon dioxide between the air and blood.
What produces surfactant?
Surfactant is produced by the type II alveolar cells in the lungs. These cells secrete surfactant which helps lower surface tension in the alveoli, preventing collapse and facilitating gas exchange.
What are the most numerous cells in the lungs?
The most numerous cells in the lungs are the alveolar epithelial cells, specifically the type I alveolar cells which make up about 95% of the alveolar surface area. These cells are responsible for gas exchange and maintaining the structural integrity of the alveoli.
What is alveolar macrophages also known as?
Alveolar macrophages, aka DUST CELLS.
What keeps the surface between the air and the alveolar cells moist in the lung?
alveolar fluid
The respiratory membrane consists of what cells?
Alveolar squamous cells and Capillary endothelial cells.
In which layer of the alveolar membrane are the cleanup cells located?
The cleanup cells, also known as alveolar macrophages, are located in the alveolar space within the alveolar membrane. They play a crucial role in clearing debris, bacteria, and other particles from the lungs to maintain respiratory health.
What is the three types of particles?
the cells,plant cells, and animal cells
Damage of septal cells of the lung?
alveolar wall
What is the three types of small particles?
the cells,plant cells, and animal cells
There are three different types of electrochemical cells?
false, there only two types of electrochemical cells. Wet and dry cells.
Lung surfactant is produced by?
type II alveolar cells
