Alveoli are tiny balloon shaped structures and are the smallest passageway in the respiratory system. The alveoli are only one cell thick, allowing the relatively easy passage of oxygen and carbon dioxide (CO2) between the alveoli and blood vessels called capillaries.


Here's the story. > Function of alveoli The function of the alveoli is to get oxygen into the blood stream for transport to the tissues, and to remove carbon dioxide from the blood stream. Structure of alveoli In the lungs, air is diverted into smaller and smaller microscopic branches called respiratory bronchioles, which connect to the alveolar ducts.


Alveoli are tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream. Learn more about how they function and quiz your knowledge at the end. 2014-09-23


You have millions of tiny air sacs working in your lungs to get oxygen into your bloodstream and take carbon dioxide out. Read about alveoli function — how it impacts your health, and how your ...


Structure and Anatomy of the Alveoli. ... What is the Function of Alveoli in the Respiratory System. The human body needs oxygen for every important cellular function, and when we inhale, we draw in this essential gas from our environment. But once the air enters the body, the gaseous oxygen needs to reach the bloodstream so it can be sent to ...


The alveoli are sac-like structures that contain air. They formpart of the respiratory system and their function is to allow forthe exchange of gases to take place.


Alveoli structure and location . The alveoli are specifically designed to effectively fulfill their function in gas exchange. An adult lung has around 300 to 400 million alveoli that are 200 to 300 microns small. They contain elastic fibers and collagen and are made up of epithelial cells.


Type II pneumocytes. The type II alveolar cells (also known as type II pneumocytes) have two functions: (1) to repair the alveolar epithelium when squamous cells are damaged, and (2) to secrete pulmonary surfactant. Surfactant is composed of phospholipids and protein, and coats the alveoli and smallest bronchioles, which prevents the pressure buildup from collapsing the alveoli when one exhales.


Alveoli functions by storing air for a short while to allow absorption of oxygen into the blood. The following Bodytomy article will cover some information related to the function and structure of alveoli.
