Chordata
The chordata is a very familiar phylum that consists of a wide variety of animals, such as humans themselves. Most of the animals in the chordata respire similarly and obtain many similar organs that attribute to breathing. The phylum chordata consists of amphibians, mammals, reptiles, fish, and birds.

Human Being (Homo sapien)
Humans can easily be distinguished from many other animals as ourselves. Humans simply breathe by inhaling oxygen and exhaling carbon dioxide. This is how oxygen reaches the blood in the body. The mouth and nose eases the process for us to inhale oxygen. The air is then carried to the throat and then to the trachea. The trachea is a tube that carries the oxygen to the lungs, and it is also known as the windpipe. The alveoli allows the passing of oxygen and carbon dioxide. The blood is then carried to the heart and the heart pumps it throughout the rest of the body to provide it with oxygen.
Birds (Aves)
Birds are warm blooded animals that contain wings for flying and beaks for obtaining food and necessities. Birds contain lungs called cervical air sacs that inhales oxygen when the chest is pushed out. Once this happens, the air sacs suck in the oxygen, causing a negative affect. Muscles have to contract for the pressure to be increased in the air sacs and for the oxygen to be turned into carbon dioxide. Since birds do not have a diaphragm, the pressure from the air sacs is relied on when breathing. In the birds lungs, the exchange of gases occurs along the walls of the microscopic tubules, also called the air capillaries. Much like humans, oxygen is inhaled through the nostrils and down the trachea. However, it goes directly to the cervical air sacs instead of to the lungs. Then, the oxygen is distributed to the rest of the body.
Lion (Pantheria leo)
Lions are cats that are members of the family Felidae. The lion breathes much like many other organisms, where oxygen is inhaled and carbon dioxide is exhaled. Lions possess two respiratory tracts, the upper and lower tracts. These tracts control the process of respiration throughout the lions body. The nose of the lion brings in oxygen and the thorax expands, thus bringing in more oxygen. When the thorax relaxes, carbon dioxide is exhaled, and the process is repeated. The oxygen attaches to the hemoglobin in the blood, and the nutrients are transported throughout the body. Carbon dioxide highly affects their pH systems, and the lack of gases makes the lions thirst for water.
