Define aerobic respiration
Respiration using oxygen
Define anaerobic respiration
Respiration May occur without the use of oxygen

Function of the nose
Take in air
Filter air with tiny hairs
Function of trachea
Take air down to lungs
Function of bronchus
A tube that carries air into a lung
Function of lung
Gaseous exchange
Function of intercostal muscles
Causes the chest to expand and contract
Function of bronchiole

What is the name of the movement of gas in the lungs called
Diffusion
Define inhale

Define exhale
To breathe out
Name 3 organs of the respiratory system work together
Nose and lung
Trachea bronchi and bronchioles
The intercostal muscles and the diaphragm
How do the nose and lungs work together
The nose helps filter and moisten the air before it reaches the alveoli in the lungs
How do the trachea bronchi and bronchiole work together
These are a system of tubes that work together to bring air down to the lungs and up from the lungs
How do the intercostal muscles and the diaphragm work together
The intercostal muscles and the diaphragm contract at the same time to draw in air into the lungs and they relax at the same time to push air out of the lungs
Function of alveolus
Air sacs for gaseous exchange
