Pharynx
Bronchus
Trachea
Epiglottis
What is the membrane that covers the lungs called?
Visceral Pleura
Parietal pleura
what happens to the diaphragm during inhalation?
contracts and flattens
contracts and goes into a dome shape
relaxes and flattens
relaxes and goes into a dome shape
how do the sternocloidomasteroid muscles aid inspiration?
contract to raise the upper half of the chest
relax to raise the upper half of the chest
contracts to help the diaphragm
what is one aim of gaseous exchange?
to get C02 into the blood stream
to get nutrients into the blood stream
to get oxygen into the blood stream
what is a waste product of aerobic respiration?
water
oxygen
nitrogen
carbon dioxide
What percentage of inhaled air is carbon dioxide?
0.3%
0.03%
3%
Diffusion is.....
movement from an area of high concentration to an area of low concentration
movement from an area of low concentration to an area of high concentration
what does oxygen attach to in the red blood cell?
capillaries
haemoglobin
water
factor 8
In working muscles there is......
high concentration of C02 and low concentration of oxygen
high concentration of oxygen and low concentration of C02
high concentration of water and low concentration of oxygen
what is tidal volume?
the amount of air breathed in and out with each breath
the amount of air left in the lungs after full exhalation
maximum amount of air that can be breathed in and out during one breath
vital capacity + residual volume
what is vital capacity?
vital capacity + residual volume
the amount of air breathed in with each breath
maximum amount of air that can be breathed in and out during one breath
the amount of air left in the lungs after full exhalation
What is residual volume?
vital capacity + residual volume
the amount of air breathed in with one breath
maximum amount if air breathed in and out during one breath
the amount of air left in the lungs after full exhalation
what is total lung volume?
the amount of air breathed in with each breath
the maximum amount of air that can be breathed in and out during one breath
the amount of air left in the lungs after full exhalation
vital capacity + residual volume
what is breathing rate controlled by?
neural mechanisms
chemical mechinisms
neural and chemical mechanisms
chemoreceptors detect an...
increase in acidity
increase in oxygen
increase in CO2
where do the chemoreceptors send a signal to?
the lungs
the heart
the medulla oblongata
the respiratory muscles
which is the correct equation for aerobic respiration?
nutrients + water = oxygen and C02
nutrients + oxygen = energy, C02 and water
energy + nutrients = oxygen, water and carbon dioxide
oxygen + nutrients = lactic acid, CO2 and water
what is responsible for producing voice?
larynx
pharynx
nasal cavity
what prevents food going into the lungs when we swallow?
epiglottis
trachea
pharynx
C - shaped cartilage
what prevents the trachea from collapsing?
muscle
cartilage
bone
residual volume
what does the bronchi divide into?
bronchioles
capillaries
alveoli
bronchus (left and right)
what surrounds the alveoli?
smooth muscle
venuoles
capillaries
arterioles
how does the signal to change breathing rate travel from the brain to the respiratory muscles?
sympathetic nerve
parasympathetic nerve
vagus nerve
phrenic nerve
