Exhalation of fish.
-When the mouth is___, the floor of the____is raised.
-Water enters through the gill___and gaseous exchange between blood and water occurs through ____.
-At the same time, the____relaxes and the____becomes smaller.
-The volume of the ____is reduced and the pressure in the buccal cavity becomes higher than the pressure outside.
-The high pressure causes water to flow through the ____.
-closed, buccal cavity
-lamella, diffusion
-operculum muscle, opercular cavity
-buccal cavity

What will happen if alveoli of an individual are torn and punctured?
Gasping
What will affects the rate of oxygen combines with haemoglobin in lungs ?
Concentration of haemoglobin, concentration of oxygen, concentration of oxyhaemoglobin
The chemical reactions that converts carbon dioxide into hydrogen carbonate ions occur in ___
red blood cells
Explain how red blood cells accept oxygen from alveoli
and transfers it to the body cells.
-Oxygen in the ____diffuses into the red blood cell.
-Oxygen combines with haemoglobin to form____and is transported to all parts of the body cells.
-blood plasma
-oxyhaemoglobin
If an individual inhales a lot of carbon monoxide, what is the effect on the transport of oxygen by red blood cells?
-Haemoglobin has a higher ability to combine with ___compared to___.
-As a result, the oxygen is unable to reach the ___especially the____.
-Hence, the___of food cannot occur and the individual faces ___.
-carbon monoxide, oxygen
-body cells, brain cells
-oxidation, death
