How many lobes does the left lung have?
Two
A malignant tumour that sees uncontrolled growth of a mass of lung tissue that invades and destroys neighbouring tissues. This is often related to smoking.
Lung Cancer
These vibrate and make sound when air passes through them.

Airways
What is the layer of membranes called that surround the lungs?
Pleura

Tonsils
To take in oxygen and expel carbon dixoide, the respiratlory system has three functions. Name two of the three functions of the respiratory system

What is between each membrane that surrounds each lung?
Liquid
Common viral disease that causes a winter pandemic every 10-15 years. It can be fatal to people in high risk groups and those who suffer from heart disease, lung infections, or other chronic infections.
Two of these tubes branch off from the trachea and carry air into the lungs
Bronchi
This fibrous structure closes to stop food from entering the airways
Epiglottis
WHere does gas exchange take place?
Bronchioles
How much air enters and leaves the lungs on each normal inhalation and exhalation?
.5 litres
