Anatomy Of Alveoli

Anatomy of the alveoli pulmonary alveolus. Alveoli are the endpoint of the respiratory system which starts when we inhale air into the mouth or nose.

Anatomy

The pulmonary alveolus is a sac roughly 02 to 05 mm in diameter.

Anatomy of alveoli. The respiratory section of the lungs is comprised of the alveoli sacs the alveolar ducts and the pulmonary alveoli. Along the length of the alveoli ducts there are small pouches known as pulmonary alveoli. The alveoli are located in the respiratory zone of the lungs at the distal termination of the alveolar ducts.

The major cell type found on the alveolar surface covering about 95 of the surface area are thin. When a breath is taken during inhalation the concentration of the incoming oxygen is. Each alveolus singular plays an important role in letting oxygen and carbon dioxide move into and from the bloodstream during inhalation and exhalation 2 3.

A diagram of the pulmonary alveolus. Air entering the lungs during inhalation travels through numerous passageways called bronchi and then flows into approximately 300000000 alveoli at the ends of the bronchioles or lesser air passages. Alveoli are the small balloon like sacks of 200 500μm diameter 1 making up a vital part of the respiratory zone of the human lungs.

Pulmonary alveolus plural pulmonary alveoli any of the small air spaces in the lungs where carbon dioxide leaves the blood and oxygen enters it. Pulmonary alveoli gather in clusters and are encased in sacs referred to as alveolar sacs. The oxygen rich air travels down the trachea and then into one of the two lungs via the right or left bronchus.

Between the alveoli is a thin layer of cells called the interstitium which contains blood vessels and cells that help support the alveoli. The same kind of thin tissue lines the inside of the chest cavity also called pleura. Learn alveoli anatomy physiology with free interactive flashcards.
