Alveoli are tiny air sacs in the lungs that facilitate gas exchange, characterized by their thin walls, which are only one cell layer thick, allowing for efficient diffusion of oxygen and carbon dioxide. They have a large surface area due to their numerous and clustered structure, maximizing the amount of gas that can be exchanged. Additionally, alveoli are lined with surfactant, a substance that reduces surface tension, preventing collapse during exhalation and maintaining their structure.

What are three characteristics of radiolarians?
Body parts include Endoplasm, ectoplasm (or calymma), and siliceous (opaline) skeleton. Alveoli are used as floatation devices.
Is there three alveoli?
The term "alveoli" refers to the small air sacs in the lungs where gas exchange occurs. Each lung contains millions of alveoli, not just three. They are essential for oxygen and carbon dioxide exchange between the lungs and the bloodstream. Therefore, the idea of "three alveoli" is not accurate in the context of human anatomy.
What are the characteristics of the alveoli that help with its function?
gas exchange is the intake of the oxygen and the let out of the carbon dioxide
What structural characteristics do alveoli and capillaries share?
They are both very thin making diffusion possible.
What structural characteristics of the alveoil makes them as ideal sitefor the diffusion of gases?
The alveoli have a thin, single-cell layer structure that minimizes the distance for gas diffusion, facilitating efficient exchange between oxygen and carbon dioxide. Their large surface area, created by millions of alveoli within the lungs, enhances the capacity for gas exchange. Additionally, the moist environment within the alveoli aids in dissolving gases, further promoting diffusion. Together, these characteristics make alveoli highly efficient for respiratory gas exchange.
What connects the respiratory and circulatory system?

Is the alveoli divided in lobes?
No, the alveoli themselves are not divided into lobes. Instead, the lungs are organized into lobes; the right lung has three lobes and the left lung has two. Alveoli are tiny air sacs located at the end of the bronchial tree within the lobes, where gas exchange occurs. Each lobe contains numerous alveoli, which facilitate the exchange of oxygen and carbon dioxide.
What is the functional unit of lungs?
alveoli
What are the three characteristics that constitutes a market?
The three characteristics are purchasing power, authority, and willingness to buy.
