True or false the fluid coating the alveoli that reduces surface tension is called surfactant?
True; produced by Type II pneumocytes
What is the function of type 2 alveoli walls?
function of type 2 alveoli cells is to secrete surfactant.
What keep the alveoli from collapsing?
Alveoli does not collapse because lungs always have a residual volume which prevents the alveoli to collapse.
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.
What cells secrete surfactant that reduces the tendency for pulmonary alveoli to collapse?
Type 2 Alveolar cells
What is the scientific name for lung cells?
Pneumocyte. There are two types: Type I cells make up the lining of the air sacks (alveoli) in the lung, type II cells produce a slick liquid called surfactant that helps coat the alveoli and keep them from collapsing when we exhale.
What type of cells are produced after meiosis?
sex cells
What are the most common cells that line the surface of the alveoli and therefore associatedwith the exchange of gases within the lungs?
Type 1 alveolar cells
What type of cells are produced during meiosis?
Gametes or sex cells
What type of electric current is produced by fuel cells and solar cells?
ac
Lung surfactant is produced by?
type II alveolar cells
What type of epithelial tissue is found in the esophagus?
Pseudostratified columnar cells line the inside of the trachea and simple squamous cells make up the alveoli
