bird




Birds have a respiratory tract terdir the nostrils, trachea, bronchus and lung APRU. At the bottom of the
trachea there is a sound tool called a siring. Bird has a breathing apparatus called the coffers of air
associated with the lungs. Function of the air sac, among others, to assist breathing and to help raise
siring cavity so as to amplify the sound. The process of breathing in birds occurs as follows. If
berkontaksi rib muscle, ribs move to the front and move to the bottom of the breastbone. The chest
cavity becomes larger and the pressure is decreased. This causes air to enter the lungs and then into the
air pocket. At the time of the rib muscles relax, broken bones moving toward the back and sternum
move upward. The chest cavity decreases and the pressure becomes large, making the air out of the
lungs. Similarly, air from the coffers of the air out through the lungs, APRU. Oxygen uptake by the lungs
occurred at the time of inspiration and expiration. Gas exchange occurs only in the lungs.

reptile

Reptiles breathe with lungs. Oxygen uptake and carbon dioxide takes place in the expenditure of the
lung. Exit and entry and exit of air from the lungs due to the movements of the rib. Respiratory tract
consists of the nostrils, trachea, bronchi and lungs.
frog

The life cycle of frogs undergo metamorphosis or change in shape. At a young age after a tadpole and
adult life on land. At Nula tadpoles breathe with gills located on the outside back of the head. The gills
are vibrating a result of water around the gills are always changing. Oxygen dissolved in water diffuses in
the blood capillaries are present in the gills.
After some time outside of the gills will turn to the gills in a way the formation of skin folds from front to
back so that the outer gill covers. Adult frog lives on land, breathing with lungs. In addition to the lungs,
oxygen diffuses in the oral cavity through the lining of the mouth and also through the skin.




Fish
mas contained breathing with gills on either side of the head. Each has four gills are covered by a
gill cover (operculum). The process of respiration in fish is by opening and closing the mouth
alternately opening and closing the gill cover. At the time the mouth opens, the water goes into
the oral cavity while closing the gill cover. Oxygen dissolved in water to diffuse into the blood
capillaries are present in the gills. And at the time of closing, opening and closing the gill cavity
of the mouth of the water out through the gills. Along with the release of water through the gills,
carbon dioxide removed. Oxygen and carbon dioxide exchange occurs in the gills of the sheet.
Insects have called Sitem respiratory tracheal system. Oxygen needed by the body's cells to
oxidation but not circulated by the blood circulated by tracheal branching throughout the body.
Small branches of the trachea that penetrate the body tissues called trakeolus. The entry of air for
breathing through the mouth but not through the stigma (spiracles).
The process of breathing in insects occurs as follows. With the contraction of the muscles of the
body, the insect's body becomes inflated and deflated regularly. At the time of the insect's body
expands, the air enters through the stigma, then enter into the trachea, then into the trakeolus and
finally into the body cells. Oxygen diffuses into the cells of the body. Carbon dioxide is expelled
through the respiratory tracheal system also eventually expelled through the stigma when the
insect's body deflates.
Earthworm
Earthworms have no special respiratory equipment. Her skin contains mucus glands, so that his
skin was wet and damp. Oxygen needed by the body go through the entire body surface
diffusion. Carbon dioxide is also spending through the body surface.

Protozoa
Protozoa have no special breathing apparatus for obtaining oxygen and removing carbon dioxide.
Oxygen into the cell plasma membrane by diffusion malalui. Similarly, carbon dioxide from the
cells through plasma membrane deikeluarkan.
