alveoli
Respiratory. They are the air sacs in your lungs.
Bronchioles are part of the respiratory system and branch from the bronchus. Air from the bronchus enters the terminal bronchioles that terminate in air sacs known as alveoli.
The RESPIRATORY SYSTEM is how you breath, so your; trachea, lungs, alveoli etc hope this helped!
Your question is unclear. Are you asking what does the most in the respiratory system , then tiny little sacs called the alveoli do.
a pulmonary artieriole is part of the respiratory system. inside the respiratory system is an organ called alveoli and the alveoli are covered in a network of capillary. the job of the pulmonary arteriole is to carry deoxygenated blood into the capillary network.
This system is called the respiratory system. It exchanges oxygen that the cells need to make energy for carbon dioxide which is a waste product that the cells make.
The lungs are intimately in contact with the cardiovascular system. The alveoli in the lungs is where gas exchange occurs from the cardiovascular system and the respiratory system.
The respiratory and circulatory systems are involved in the exchange of gases between the alveoli and blood. The alveoli are part of the lungs, and their surrounding capillaries are part of the circulatory system.
The capillaries surrounding the alveoli at the ends of the bronchioles in the lungs.
In the respiratory system, it is the alveoli.In the circulatory system, it's the capillaries.They are similar in that both have walls that are only one cell thick, they are both the thinnest parts of their systems, and they are right next to each other. (They diffuse through to each other.)In the respiratory system it's the Alveoli and in the circulatory system it's the capillaries :D
trachea --> bronchi -->bronchioles --> alveoli
