Paragraph 1: What happens in the respiratory system?
Respiratory System: Coordinating the Supply and transport of Oxygen
* Oxygen is inhaled through the nose or mouth * Travels down through the Pharynx * Travels down the Larynx * Reaches the lungs and goes through the Bronchi * Through the Bronchioles * Then reach’s the Alveoli * The Oxygen then leaves the lungs and is transported around the body via blood vessels
* Deoxygenated blood carries the Carbon Dioxide back to the lungs * The deoxygenated air then retraces its steps * Back to the Alveoli * To the Bronchioles * Through the Bronchi * Through the Larynx and Pharynx * Then finally out of the nose or mouth.
Paragraph 2: Circulatory System
Blood transportation
- The heart sends blood around your body. The blood provides your body with the oxygen and nutrients it needs. It also carries away waste such as carbon dioxide.
-Your heart is sort of like a pump. The right atrium of your heart receives de-oxygenated blood from the body and pumps it through the valve to the right ventricle, back to the lungs so that it can be re-oxygenated.
-The left atrium receives blood from the lungs where it is passed through another valve into the left ventricle then pumped out into the body.
- Blood is pumped and circulated through the body via blood vassals.
- An adult has an average of 5 liters of blood in the body; the circulatory system carries this entire quantity on one complete circuit through the body every minute.
-It equalizes body temperature and helps maintain normal water balance.
Paragraph 3:
How is it possible? What allows it to happen?
+The Pharynx has hairs to filter air.
+The Trachea is lined with mucus secreting cells.
+Bronchi and Bronchioles get air deep
