Yes. Alveolus is composed of many cells that work for a common function, to take out carbon dioxide and oxygenate the blood.
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.
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.
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.
By the lungs and alveoli.
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).
From the Alveoli, it transfers to red blood cells, which travels through the circulation and reaches the heart.
Its in alveoli of lungs
alveoli
thay are both thick cells :)
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.
Neither, alveoli are the air sacs within the lungs in mammals (singular alveolus).
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.
