the effect of carbon dioxide concentration on the uptake and release of oxygen by haemoglobin.
Bohr effect
1 of 19
the number of breaths (inhalation and exhalation) taken per minute.
breathing rate
2 of 19
the compound formed when carbon dioxide combines with haemoglobin.
carbominohaemoglobin
3 of 19
enzyme which catalyses the reversible reaction between carbon dioxide and water to form carbonic acid.
carbonic anhydrase
4 of 19
the movement of chloride ions into the red blood cells as hydrogen ions move out to maintain the electrochemical equilibrium.
chloride shift
5 of 19
the ability to return to original shape and size following stretching.
elastic recoil
6 of 19
the compound formed when haemoglobin accepts free hydrogen ions in its role as a buffer in the blood.
haemoglobinic acid
7 of 19
chemical mixture containing phospholipids and both hydrophilic and hydrophobic proteins, which coats the surfaces of the alveoli and prevents them collapsing after every breath.
lung surfactant
8 of 19
the bony flap covering the gills of bony fish. Part of the mechanism that maintains a constant flow of water over the gas exchange surfaces.
operculum
9 of 19
the gaseous exchange organs of fish, comprised of gill plates, gill filaments and gill lamellae.
gills
10 of 19
graph showing the relationship between oxygen and haemoglobin at different partial pressures of oxygen.
oxygen dissociation curve
11 of 19
blood that has passed through the gas exchange organs (e.g. lungs) and is high in oxygen.
oxygenated blood
12 of 19
the volume of air that is left in the lungs after forced exhalation. It cannot be measured directly
residual volume
13 of 19
the volume of air which moves into and out of the lungs with each resting breath.
tidal volume
14 of 19
the sum of the vital capacity and the residual volume.
total lung capacity
15 of 19
the main airway, supported by incomplete rings of cartilage, which carries warm moist air down from the nasal cavity into the chest.
trachea
16 of 19
fluid found at the ends of the tracheoles in insects that helps control the surface area available for gas exchange and water loss.
tracheal fluid
17 of 19
is the total volume of air inhaled in one minute. Ventilation rate = tidal volume × breathing rate (per minute).
ventilation rate
18 of 19
volume of air that can be breathed in when the strongest possible exhalation is followed by the deepest possible intake of breath.
vital capacity
