Organ of Smell

Question 10

Serves as passageway for air and food

Answer 10

Pharynx

Question 11

Also known as the voice box

Answer 11

Larynx

Question 12

Also known as the windpipe. A long tube ised for air passage.
In line with epithelium cells with goblet cells where mucus is produced

Answer 12

Trachea

Question 13

Consist of Primary Right and Left Bronchus. Tree Like formation

Answer 13

Bronchi

Question 14

Small divisions of Bronchi.

They conduct air into alveoli

Answer 14

Bronchioles

Question 15

Also known as air sacs. Surrounded with gas capillaries to allow gas exchange.

Answer 15

Alveoli

Question 16

Define Respiratory System

Answer 16

Supply cells with oxygen and removes carbon dioxide produce by them

Question 17

Mechanics of Breathings

Answer 17

Inspiration

Expiration

Question 18

Exchange of gases between the body and the environment

Answer 18

Respiration

Question 19

Exchange of gases in the lungs - oxygen diffuses from the air into the blood, and carbon dioxide diffuses from the blood to the air.

Answer 19

External respiration

Question 20

Exchange of gases in the body tissues - oxygen diffuses from the blood to the cells and carbon dioxide diffuses from the cells to the blood

Answer 20

Internal Respiration

Question 21

The chemical, energy generating activity of the cell

Answer 21

Tissue

Question 22

How does the respiratory system work?

Answer 22

1. Diaphragm contract allowing more room in the chest cavity
2. Oxygen rich air enters nose or mouth
3. Air travels through larynx, trachea to the 2 bronchial tubes
4. Bronchial tubes are split into bronchioles to which air travels
5. Air enters capillary lined sacs called alveoli
6. Pulmonary artery brings carbon dioxide rich blood to the capillaries and exchanges oxygen
7. Oxygen rich blood travels to the pulmonary vein to various parts of the body
8. Diaphragm relaxes and carbon dioxide follows the reverse path that the oxygen travelled and is exhaled.

Question 23

Factors that control breathing: (BBMS)

Answer 23

Blood carbon dioxide and oxygen concentration
Body temperature
Mechanical or Chemical Irritation
Stretch of Respiratory Muscles

Question 24

What are the 5 protective mechanisms of the respiratory system?

Answer 24

Bronchospasms 
Cough
Ciliary Movement
Mucus Secretion
Macrophages - white blood cells in the alveoli
