Alveolar sacs is the structural unit of lungs.
Tiny blood capillaries fuse together to make up an alveolar sac.
This structure of the sac is very important for the easy diffusion of respiratory gases across the membrane.

What is the function of air sacs?
The function of air sacs (alveoli) is to provide a large surface area for gas exchange
What is a thin-walled air sac that serves as a site for gas exchange is called?
An alveolus is a single air-sac, and alveoli are multiple air-sacs.
Air travels in what order through the human body?
nose, nasal passageway, pharynx, larynx, trachea, bronchi, bronchial tubes, bronchioles, air sacs, alveol
Sacs that contains materials in a eukaryotic cell?
They are known as Cytoplasmic Vesicles, such as lysosomes and peroxisomes. Another separate class is the Organelle, such as the Mitochondria and the Nucleus.
The blood gains its oxygen in which part of the body?
The blood gets oxygen in the heart. Once the oxygen has been replenished, the blood is sent back out to the organs.
What might cause damage to the alveolar sacs?
Environmental conditions such as pollution and smoke could permanently damage the alveolar sacs.
What is a another name for alveolar sacs?
lion
What is the endpoint of bronchioles?
Respiratory bronchioles end in alveolar sacs (alveoli).
What kind of epithelial tissue is in the alveolar sacs of the lungs?
Simple Squamous
What is emphyzema?
Hyper inflation of air sacs with destruction of alveolar walls.
Alveolar ducts alveolar sacs terminal bronchioles respiratory bronchioles bronchi bronchioles What is the order from largest to smallest?
The respiratory looks like an upside down tree, from the trunk to the branches and to fruit (such as an apple). From largest to smallest, the respiratory system consists of the throat to main bronchi, to bronchioles, to terminal bronchioles, to alveolar ducts, to alveolar sacs (aveoli look like tiny grapes).
Where does Vesicular breathing sounds probably result from?
Air filling the alveolar sacs.
What kind of epithelial tissue is found in alveolar sacs of the lungs?
Simple Squamous
What is air sacs within the lungs?
Alveolar means pertaining the the alveolus (plural alveoli), the small air sacs in the lungs.
What is alveolar ventilation refers to?
Alveolar volume is lung capacity. Alveoli are the air sacs in the bronchioles. How much air the lungs hold during both inspiration and expiration is lung capacity which is alveolar volume. Hope this helps
Which part of the respiratory system consists of air sacs with capillaries?
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.
How many alveoli's or minute sacs are there in our lungs?
There are approximately 300 million alveolar sacs in the human body. The range in size from 70-300um(micro meters) in Diameter.
