The chordata phylum is the phylums that consists of animals possesing a notochord. Animal in the phylum chordata are mammals, fish, amphibians, retiles, and birds.
Homo Sapien
- Human breathe through their nose and mouth using their diaphram. Humans inhale air containing oxygen, it travel through their mouth then down their trachea until the trachea divides into two seperate bronchial tubes. Then the air moves into their lungs. As the air pass through the bronchial tubes, the tubes divide into smaller tubes known as bronchioles that are in the lungs. The bronchioles end in tiny air sacs called alveoli. The human bods has over 3 million aveoli. The aveoli are surrounded by tiny blood vessels called capillaries, oxygen pss through the walls of the aveoli and into the blood. Then, the blood leaves your lungs and goes to the heart which pumps the blood containing oxygen all throughout the human body. As the oxygen is used, carbon dioxcide is produced and absorbed into the blood. It is then transported by the blood to your lung to be excreted when a human exhales.
Panthera tigris
Tigers respire the same way as humans. They inhale air through their mouth and nose. Then the air goes down the trachea and in the bronchial tubes. Then te air goes into the alveoli. The oxygen goes through the alveoli and into the capilaries which contain blood. The oxygen is absorbed by the blood. The blood is then sent to the heart to be distributed thoughout the body. As the oxygen is broken down and used, carbon dioxcide is produced. The carbon dioxcide is sent back to the lungs through blood to be excreted when exhaling. Tigers also use a diaphram to inhale and exhale.
Anura
Anura or also known as frogs or toad have a very complex way of respirating. They have three different types, cutaneous(skin), buccal(mouth), and pulmonary(lungs). In the cutaneous respiration, the skin of the frog or toad exchange gasses with air and it laso can absorb water. Then, the frog is out of water, the mucus glands help keep the frog moist which helps absorb dissolved oxygen from the air. Th skin is then connected to many capillaries which distribute the oxygen. The second type of respiration is buccal, air is inhaled through the nostris and they have the same two lungs as a human and lion but they do not have a diaphram so they open their mouth to increase pressure to inhale air through their nostrils. Th third type is the lungs which is the same as a human and tiger. It contains the same parts including the 2 lungs, trachea, heart, alveoli, and capillaries.
