1. Human Respiration
Parts and Functions

2. Function:
The primary function of the respiratory system is GAS EXCHANGE
Taking in Oxygen
Removing Carbon Dioxide
The actual conversion process of Cellular Respiration takes place in the mitochondria!
Glucose + Oxygen Carbon Dioxide + Water

3. Parts: Nose and mouth Sinus Trachea Bronchi Bronchioles Lungs Alveoli
Diaphragm

4. Functions: Match the column!
Nose and mouth
Sinus
Trachea
Bronchi
Bronchioles
Lungs
Alveoli
Diaphragm
Actual site of gas exchange
Muscle that pulls air into lungs
Air tube surrounded by cartilage
Where air comes in
Contain alveoli, able to fill with air
Place where air is warmed
Where bronchi split into smaller tubes
Where trachea splits, one tube to each lung.

5. How do we breathe? The diaphragm contracts and pulls down
The negative pressure pulls air into mouth and nose

6. How does this connect to circulation?
Oxygen in air is picked up by small capillaries around the alveoli
Red blood cells actually carry the oxygen
The blood travels to the heart and is pumped to the body
Blood from the body high in CO2 goes back to the heart, pumped to lungs
CO2 moves from the blood back into the lungs and is exhaled!
