Bronchi
Paired of organs of respiration in the thoracic cavity
Lungs

Alveoli are tiny sacs attached to the ends of the smallest bronchioles and encased in _______
capillaries
Oxygen from the air breathe-in passes readily to the blood in the capillaries
At the same time, ________ passes from the blood into the airspaces of the alveoli and is exhaled
carbon dioxide
- This is the muscular partition separating the abdominal and thoracic cavities
- It is an accessory muscle of respiration
