4. The organisms too breathe like man.
Cellular respiration is almost similar
in all organisms.In different organism
breath different organ to their
respiration.
5. AMEOBA
The Amoeba cell
membrane it self acts
as the respiratory
surface. Oxygen enters
and carbondioxide
exit through this
membrane.
6. EARTHWORM
• Skin is the respiratory organ
of the earthworm. There are
many blood capillaries in
the skin. Oxygen from the
atmosphere diffuses into the
blood and carbondioxide
from the blood diffuses out
to the atmosphere through
the moist skin
7. COCKROACH
The respiratory organ of the
cockroach is a network of
tubules spread all over its
body. These are known as
trachea. These open to the
outside through openings
called spiracles.
8. SCORPION
• Book lungs are the
respiratory organ of the
scorpion. They are seen
towards the posterior
end of the abdominal
cavity. Oxygen present in
the air enters inside
through the openings and
dissolves into the body
fluid. Carbondioxide is
expelled from the body
fluid.
9. FISH
Gills are the
respiratory organ to
fish. They are rich in
capillaries. Oxygen
form the water that
flows continuously
over the gills diffuses
into the blood and the
carbondioxide diffuses
into the water.
10. FROG
• The frog which is an
amphibian can breath both
in air and water. Moist skin
bucal cavity and lungs are
the respiratory organs of
frog. But tadpoles, the
larvae of frog breathe
through gills are they are
completely aquatic
11. The structure of respiratory organs and the
process of respiration become more complex
as the complexity in the structure of
organisms. Cellular respiration is almost
similar in all organisms.
