remove carbon dioxide
remove water vapour

the use of intercostal muscles
the use of a muscular diaphragm

something different
The normal oxygen content of inhaled air is approximately
0.04%
21%
79%
100%

The main tube connecting the mouth to the lungs is the
alimentary canal
oesophagus
trachea
something els
From the trachea the airway splits into
brachycardia
breathers
bronchioles
brioche
Specialist cells in the bronchioles have structures on them called
alveoli
cilia
dermacytes
erythrocytes
Why do you need mucous membranes in the bronchioles?
to help the food go down smoothly
to stop the air irritating them
to help air pass through
to trap and remove foreign particles
At the end of the bronchioles are structures called
alveoli
blastocytes
villi
none of these
How are alveoli and villi similar
they are not
by cell thickness
by where they are in the body
by how they deal with foreign proteins
The exchange of oxygen and carbon dioxide in the alveoli is through a process called
active transport
conduction
convection
diffusion
The lungs are in a body cavity lined with
ciliated cells
mucus
pleural fluid
water
Which of these are diseases of the respiratory system
asthma, angina, COPD
angina, COPD, aspergillosis
asthma, angina, aspergillosis
aspergillosis, asthma, COPD
Asthma is a condition where
the airways narrow
the airways are blocked with mucus
the diaphragm fails to work
all of these
How is Cystic Fibrosis different from COPD?
its not really
Cystic Fibrosis also affects the digestive system
Cystic Fibrosis also causes swelling of the heart
