it is called a vacuole
In the pulmonary system, the Alveoli are the small sacs at the end of the bronchioles which are connected to the bronchus. It is within these sacs that gas exchange occurs.
In a chloroplast, the stacks of membranous sacs are called thylakoid membranes. Grana is the term used to refer to the stacks of thylakoids. It is in this internal part of the chloroplast where photosynthesis occurs.
Little sacs called alvioli-- in the lungs.
The air sacks which provide the surface through which gas exchange occurs are called alveoli.
The exchange of gases inside the lungs actually occurs inside tiny sacs called alveoli. These alveoli are surrounded by capillaries where oxygen from inhaled air diffuses into the bloodstream, and carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled.
Yes, the clusters of air sacs in the lungs where gas exchange occurs are called alveoli. They are surrounded by a network of capillaries, allowing for the exchange of oxygen and carbon dioxide between the blood and air.
In mammals, air enters the lungs through tubes called bronchi, which branch into smaller tubules called bronchioles. These bronchioles extend out to tiny air sacs called alveoli, where gas exchange occurs.
Egg sacs for sharks are called well, egg sacs. However, baby sharks that come OUT of the egg sacs are called pups. Is that what you were trying to ask? If not, I hope I answered your question well enough.
Alveoli
They are called alveoli.
An individual air cell is called an alveolus (plural: alveoli) in the lungs. Alveoli are tiny air sacs where gas exchange occurs during the process of breathing.
alveoli. they are the basic functional unit of the lungs. it is where gas exchange occurs.
