Yes. Alveolus is composed of many cells that work for a common function, to take out carbon dioxide and oxygenate the blood.

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.


When oxygen is being carried back to blood cells?

Oxygen is transferred to blood cells in the capillaries around the alveoli. It diffuses from the alveoli into the bloodstream, and to the hemoglobin molecule.


What is the function of type 2 alveoli walls?

Type 2 alveoli cells secrete surfactant, which helps to reduce surface tension in the alveoli. This allows for easier expansion of the alveoli during inhalation and prevents them from collapsing during exhalation, promoting efficient gas exchange.


How do human cells get rid of waste?

By the lungs and alveoli.


Is the alveoli comprised of millions of cells?

No, alveoli consist of flattened epithelial cells which make the diffusion rate faster (by the reducing the distance the path that oxygen has to diffuse through).


How does oxygen from the alveoli reaches the heart?

From the Alveoli, it transfers to red blood cells, which travels through the circulation and reaches the heart.


Where does the air meet the red blood cells at?

Its in alveoli of lungs


What cells make your Respiratory system healthy for humans?

What do the alveoli and blood capillaries have in common and why?

thay are both thick cells :)


What cells secrete surfactant that reduces the tendency for pulmonary alveoli to collapse?

Type II alveolar cells in the lungs secrete surfactant, which is a specialized fluid that lowers surface tension in the alveoli. This reduces the tendency for the alveoli to collapse during exhalation and helps maintain the elasticity of the lungs for efficient gas exchange.


Is a alveoli cell a plant or animal cell?

Neither, alveoli are the air sacs within the lungs in mammals (singular alveolus).


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.
