1

Respiratory system

Facilitates the exchange of gases between the air we breathe and our blood

2

Lungs difference

Left: has two lobes- cardiac notch to accumulate the shape of the heart
Right: three lobes- slightly thicker, broader and shorter than left

3

Bronchi

Former from breaching of trachea

4

Alveoli

Covered in tiny capillaries
It is here the alveolar and capillary walls that the actual exchange of gases occurs across a thin membrane

5

Pulmonary ventilation

Breathing
Movement of air from the atmosphere into the alveoli

6

Pulmonary diffusion

Exchange of oxygen and carbon dioxide between the lungs and the blood

7

Transport of respiratory gases

Transportation of oxygen and carbon dioxide between the lungs and the tissue cells of the body via the blood

8

Internal respiration

Exchange of gases between the blood and capillaries and the tissue cells

9

Respiration process

Breathing- moving the air into and out of lungs (ventilation)
External respiration- exchanging gases between the air in the lungs and the blood
Gas transport by blood: transport of oxygen to the body cells and the return of carbon dioxide
Internal respiration: exchanging gases between the blood and the body cells
Cellular respiration:using the oxygen in cell processes and the production of carbon dioxide

10

Respiration equation

Food+oxygen---- energy+CO2+H2O
