alveolar = air sac simple squamous epithelium; single layer of flattened cells with disc-shaped central nuclei and sparse cytoplasm; the simplest of the epithelium. function: allows passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosae. location: kidney glomeruli; air sacs of the lungs; lining of hear, blood vessels, and lymphatic vessels; lining of ventral cavity (serosae).
Simple Squamous
Alveolar means pertaining the the alveolus (plural alveoli), the small air sacs in the lungs.
Simple Squamous
Damage to the alveolar sacs can be caused by smoking, air pollution, respiratory infections, or long-term exposure to harmful fumes and chemicals. These factors can lead to conditions like emphysema, fibrosis, or bronchiectasis, all of which can impair the function of the alveolar sacs in the lungs.
There are approximately 300 million alveolar sacs in the human body. The range in size from 70-300um(micro meters) in Diameter.
The cells lining the air sacs in the lungs make up the alveolar epithelium. These cells are responsible for gas exchange, allowing oxygen to move from the air into the bloodstream and carbon dioxide to move out of the bloodstream into the air sacs to be exhaled.

No, the alveolar duct does not have cartilage. It is a structure within the lungs that connects the respiratory bronchioles to the alveolar sacs where gas exchange occurs. Cartilage is primarily found in the larger airways of the respiratory system to provide structural support and maintain airway patency.
That sounds like a general description of the LUNGS.The lungs are loaded with pulmonary alveoli: small outpouchings along the walls of the alveolar sacs and alveolar ducts; through them, gas exchange takes place between alveolar gas and pulmonary capillary blood.
it dissolves oxygen in the fluid and from there it can diffuse to the alveolar cells.It goes right back to evolution where single cells have to absorb oxygen from water.All of our cells systems ae aquatic.
Alveolus is a single structure in the lungs where gas exchange occurs, while alveolar sac is a cluster of alveoli where multiple gas exchange processes happen simultaneously. Alveolar sacs are made up of multiple alveoli grouped together.
Intra-alveolar means between the alveoli. Focal means within a limited area. There are both adjectives and the phrase is missing a noun. (In other words, focal intra-alveolar...what?)
