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.

alveoli
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.
Why lungs are spongy?
They absorb oxygen, then release carbon dioxide. Like a sponge, it absorbs water, and releases the soap and water mixture.
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.
Are alveoli cells?
Yes. Alveolus is composed of many cells that work for a common function, to take out carbon dioxide and oxygenate the blood.
Where does the air meet the red blood cells at?
Its in alveoli of lungs
