Structure and function of the airway?
The airway of the respiratory system is mainly to do with the trachea, bronchi, bronchioles and the alveoli duct. Trachea composes of Pseudostratified columnar, ciliated epithelium, Goblet cells, Sero-mucous glands and Cartilage rings. Its main function is to allow air to pass and reach the bronchioles and to trap dust by the presence of the cilia lining its epithelium membrane. The bronchi is composed of Pseudostratified columnar, ciliated epithelium (shorter), Goblet cells (fewer), Sero-mucous glands, Cartilage, Smooth muscle. main function is to bring air into the lungs because their walls are too thick to permit gass exchange. The bronchioles is made up of Simple columnar or cuboidal & ciliated epithelium,No goblet cells,Smooth muscle (relatively abundant), Clara cells is to permit the movement of gas int the alveoli duct in-order for gaseous exchange to take place.

Which source provides moisture to the terminal bronchioles?
The moisture in the terminal bronchioles is provided by the mucous glands and goblet cells present in the bronchial walls. These cells secrete mucus, which helps to keep the airways moist and trap inhaled particles for removal by the cilia lining the bronchioles.
What kind of blood cells surround the alveoli?
Alveoli are covered with capillaries. The deoxygenated blood that has come into the lung through the arteries flows through these capillaries, getting rid of carbon dioxide and accepting oxygen from the air that has been brought into the alveoli by the bronchioles. The carbon dioxide travels back out of the alveoli, through the bronchioles, into the bronchial tube system, and out the trachea each time you exhale.
Are there mucous glands in the bronchioles?
No, bronchioles do not contain mucous glands.
What happens at the very end of the bronchioles when the air reaches the alveoli?
it is tranfered through the alveoli to the red blood cells which Carrie it throughout the human body . when it gets back they remove the CO2 and send it back through the bronchials to be exhaled
How do ciliated epithelial cells keep bronchioles clean?
the goblet cells in the bronchioles produce a mucus which traps foreign substances in the airway such as pollen, pathogens and dust particles. The cilia of the ciliated cells will then waft the mucus and the trapped particles up to the larynx where it can be swallowed and the pathogens can be destroyed by the stomach acid. The cilia can waft due to the energy produced in the cells (in the form of ATP) by the mitochondria.
What is commonly found wedged between simple columnar epithelial cells?
Goblet cells
When you breath in air where is the air going?
It goes down the trachea, through the bronichi and bronchioles, and into the alveoli. There, some of the oxygen in the air that you breathed in is accepted by red blood cells. The rest is breathed out.
What are mucus producing cells?
The cells that makes mucus are called goblet cells. These are glandular simple columnar epithelial cells that secrete gel forming mucins, which are the major component of mucus.
What is the roll of the lungs in the circulation of blood in your body?
The lungs take in Oxygen which is carried by the blood to the cells of our body in order for respiration to occur and we get energy. The transfer of Oxygen to the blood happens in the Alveoli. The Alveoli are little bumpy ball like things at the end of the bronchioles in our lungs. The Carbon Dioxide is taken out of our blood in the Alveoli too.
What is the function of the bronchioles of the lungs?
ANSWER:The bronchi (singular: bronchus) are where air entering the lungs is sent to each lung. The bronchioles are smaller airways branching off from the bronchi that send the air on to the inside walls of the lungs where the alveoli allow the oxygen to be absorbed by the blood cells and oxygenate the blood for transfer throughout the body.
