What happens in the respiratory system?
We breathe in air consisting of oxygen through or nasal cavity or mouth. This air goes into the the trachea and then splits off into the two lungs, and finally to the alveoli (air sacs). Blood capillaries containing deoxygenated blood are wrapped around the alveoli. The oxygen enters the capillaries, while the carbon dioxide goes back in the air sacs. Then, the carbon dioxide goes back up the trachea and out of the mouth or nasal cavity. Then, the process repeats again with a new breath.
Alveoli are microscopic air sacs branching off the?
respiratory bronchioles

A very tiny tube that dead ends in a sac within the lungs?
Bronchioles. Air enters through the mouth, down the trachea and into the left and right main bronchi (which lead to the left and right lungs respectively) The bronchi then branch off continually into smaller and smaller bronchi. The very smallest of these are called bronchioles and they end in tiny air sacs called alveoli.
What do plants help?
They help us because they give off the air we need to breath. They help us because they give off the air we need to breath.
What do air tubes do in the respiratory system?
Starting from the left and right bronchi, bronchus for singular, these branch down from the trachea. Then the bronchi branch off to smaller bronchi and these branch off to bronchioles. The bronchioles contain air sacs at the end called alveoli and alveolus for singular.
What do dolphins give off into the air?

What air does kelp give off?
