Features Helping Gas Exchange
13 Questions
1 of 15
What are the 6 features in the body helping gas exchange occur?
A respiratory surface ; A set of tubes ; A blood supply ; A ventilation system ; Pleural membranes ; Pleural fluid
2 of 15
Now explain what each of the following does + answer the questions
.
3 of 15
A Respiratory Surface
Membranes lining the alveoli in the lungs
4 of 15
What is another name for the alveoli?
Air Sacs
5 of 15
A Set of Tubes
Allow air from the outside to reach the respiratory surface ; C-shaped cartilage rings prevent walls of trachea and bronchus collapsing
6 of 15
What are the 5 tubes carrying the air?
Pharynx ; Larynx ; Trachea ; Bronchus ; Bronchioles
7 of 15
A Blood Supply
Carry dissolved gases to and from the respiratory surface
8 of 15
What 2 tubes carry the blood supply?
Pulmonary artery and Pulmonary vein
9 of 15
A Ventilation System
Keeps a good flow of air over the respiratory surface
10 of 15
What 2 things does the ventilation system consist of?
The intercostal muscles and the diaphragm
11 of 15
Pleural Membranes
Form an air-tight seal around the lungs
12 of 15
What are pleural membranes?
2 thin, moist membranes
13 of 15
Pleural Fluid
Acts as a lubricant, so the surfaces of the lungs don't stick to the inside of the chest walls when we breathe
14 of 15
What is the pleural fluid and where is it found?
A thin layer of liquid in the pleural cavity (the space between the 2 membranes)
