The breathing system of a mammal consists of a pair of lungs laying in the thoracic cavity, also known as the chest cavity. They are protected by the ribs. Air enters the lungs through the mouth or the nose. It then flows through the trachea. The trick here then branches out into two Bronchi that enter each of the lungs. The bronc I subdivide into numerous tubes called bronchi holes at the end of each funky. Oh, our air sacs called alveoli. It is important to note that a single air sac is referred to as an al viola. In plural, they are called alveoli. The alveoli are surrounded by capillaries which carry blood to the alveoli. I have a higher concentration of oxygen, while the capillaries have a higher concentration of carbon dioxide, the oxygen enters the capillaries, while carbon dioxide enters the alveoli through the process of diffusion To this exchange the blood gets oxygenated. The carbon dioxide that remains in the alkali is then exhaled. Mhm
