The respiratory system of a mammal serves the purpose of allowing the panda to be able to breath. When the panda breathes, is assists in getting rid of carbon dioxide and most importantly oxygenates our body so that it is is able to perform its daily functions. During inhalation the diaphragm of the animal contracts and air is allowed into the panda's lungs. Once the air has been held in the lungs for the gaseous exchange to take place , exhalation takes place. During the process of exhalation the diaphragm relaxes, pushing the air back out of the lungs and through the mouth.
Gaseous Exchange
This respiratory system is made up of the lungs, trachea, bronchi, bronchioles and the alveoli and … km of capillaries. The way that this oxygen is supplied to the rest of our body is through the process of the gaseous exchange. This process is caused when the oxygen is inhaled through the moth, down the trachea, through the bronchi’s, through the bronchioles and into the alveoli. Once the oxygen reaches the alveoli and then undertaken this gaseous exchange. This strands of capillaries the size of one strand of your hair lies beside the alveoli’s. Once the oxygen fills the alveoli it transfers through the walls and is absorbed by the red blood cells in the capillaries and is then transferred around the rest of the body. After all of the oxygen is absorbed out of these capillaries, it is replaced with carbon dioxide and is transported back to the lungs and is exhaled out of your mouth.
