Core 2: CQ1 P3

Question 1

Respiratory system

Answer 1

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

Question 2

Lungs difference

Answer 2

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

Question 3

Bronchi

Answer 3

Former from breaching of trachea

Question 4

Alveoli

Answer 4

Covered in tiny capillaries

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

Question 5

Pulmonary ventilation

Answer 5

Breathing

Movement of air from the atmosphere into the alveoli

Question 6

Pulmonary diffusion

Answer 6

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

Question 7

Transport of respiratory gases

Answer 7

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

Question 8

Internal respiration

Answer 8

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

Question 9

Respiration process

Answer 9

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

Question 10

Respiration equation

Answer 10

Food+oxygen—- energy+CO2+H2O
