There are 3 "labels"
in the whole respiratory system. This parts conform the first label: NOSE: its form is determined by the nasal bones and cartilages, and the septum helps separates the cavity in two; its located above the mouth; its function is
to make the air pass to our lungs and breathe. PHARYNX: It is thick and is a cone-shaped passageway; located behind the mouth and nasal cavity; function is to allow air to pass to the nasal cavity. LARYNX: it has 6 different small cartilages and it has lots of muscles; located between the pharynx and trachea; function is to allow air to pass and block food and water to not drown. TRACHEA: is a wide, hollow tube; located under the larynx; provide air flow from the lungs. BRONCHI: stable, made up of cartilages; located at the middle lungs; function, to shuttle air from the lungs. LUNGS: spongy and air filled; located on the chest; function, to process the air.
Outer Organs
leaf-shaped flap of cartilage located behind the tongue and above the larynx; function, to seal the windpipe while we eat. PULMONARY ARTERIES: are small and thick-walled located on the heart and they serve to carry blood to the lungs. UPPER, MIDDLE, AND LOWER LOBES: there are 3 in the right lung and 2 on the left one; located at the upper, middle and lower part of the right lung and at the superior and inferior parts of the lung in the left lung. All lobes have the same function, to bring oxygen to the bloodstream and remove carbon dioxide from there. They can also be removed from you if you have a disease, to save your life.
The organs inside
the outer organs are the next: NASAL CAVITY: is a large, air-filled space located behind the nose and in the middle face and it functions to filter the air, keep our nose humid and to block dust or dirt inside our nose. EPIGLOTTIS: its a

Here is finally the
last label. BRONCHIOLE: they are approximately 1mm or less in diameter and it is a smooth muscle. Its located inside the lungs and their function is to ensure that the incoming air is delievered to the alveolus.
TERMINAL BRONCHIOLE: they are lied with a simple cuboidal epithelium; they are located at the end of the bronchioles; function is to pass the air to the alveoli. RESPIRATORY BRONCHIOLE: they have a 0.5 diameter and it has alveoli in their walls. They are located inside the lungs and they serve to deliever air to exchange surfaces, like the alveoli. CAPILLARY BEDS: they are very thin, have a 0.5mm diameter, and they have 2 cell layers; located between the arterioles and capillaries; they serve to allow nutrients to pass. ALVEOLI: they are moisty, and thin. Located at the end of the bronchial tubes. Function is to exchange oxygen and carbon dioxide molecules.
