What is the function of bronchus respiratory system?
You do not have anything like bronchus in your lungs. Air passes from nose to pharynx, larynx and then to trachea. Trachea divides into two branches. One each for both lungs. Each of them is called as primary bronchus. Each divide into ten branches. Each of them divide into two branches. This type of branching reapeates for about seventeen times. So at last you have terminal bronchioles. So number of bronchi is very large. This is there to increase the surface area of the gaseous exchange. Function of the bronchi is to transfer the air to alveoli. to get the number of alveoli, you have to multiply the number of bronchi six more times. This gives you the surface area of about hundred squre meters for gaseous exchange.
What is the difference between trachea and bronchi?
Bronchi (plural of bronchus) are tubes that branch off from the trachea into each lung. Bronchioles are smaller tubes that branch off from each bronchus. Also there are only two bronchi compared with the hundreds of bronchioles
What are the small branches of the bronchial called?
BronchiolesThe bronchioles or bronchioli are the first airway branches that no longer contain cartilage. They are branches of the bronchi, and are smaller than one millimeter in diameter.There are no glands or cartilage in any of the bronchioles, and the epithelial cells become more cuboidal in shape.The bronchioles terminate by entering the circular sacs called alveoli.Control of airflow resistance and air distribution in the lungs is controlled by the bronchioles.
What are bronchi coated with?
The bronchi are located in the lungs and are coated with mucus. They also have cilia which are small hair-like projections on the surface of the bronchi that move the mucus towards the outside of the body.
The effects of smoking on lungs?
Smoking is never good for the lungs, and that is true no matter what it is that you are smoking. The smoke coats the lung surface and makes it dirty; it is difficult for lungs to clean themselves. Coughing, difficulty breathing, lung cancer, and emphysema are all likely to result from prolonged smoking.
What is the function of bronchial trees?
Each bronchiole ends in a cluster of air sacs called alveoli. In the alveoli gases are exchanged during respiration. bronchus(bronchi-plural) held open by cartilage, they convey air into each lung. The bronchi are lined with mucous membrane and ciliated cells which trap and help in the removal of any dirt and dust that enters
Trachea and bronchi?
If you mean what they are, trachea is more commonly known as the windpipe, and bronchi are like small branches inside your lungs to increase surface area. But this sounds like homework. You should really do ti on your own, believe me. I'm in IGCSE now, year 11 England/ 12 America. Listen to me orelse your grades wont be too goot.
What is surface area and how you can decrease or increase surface area?
You can increase surface area by spreading the object
What Type of epithelial in lungs?
The ciliated columnar epithelium lines the trachea(windpipe) and bronchi(lungs). The squamous epithelium forms the delicate lining of cavities(nose and alveoli etc.)
When you crush a solid do you increase or decrease surface area?
You increase the surface area
What does it mean to increase the surface area of a solid?
increase the surface area of a solid means to increase the area of solid
What are element of respiratory system?
1) Nasal passage- This is your nose. Air enters here and is moistened, warmed, and cleaned. 2) Trachea- Your windpipe. It is held open by rings made of cartilage. Air passes through here. 3) Bronchi- Two tubes that branch from your Trachea. They each lead to a lung. 4) Bronchioles- Smaller branches coming from the Bronchi. 5) Lungs- An organ containing alveoli. 6) Alveoli- The smallest working part of the respiratory system, and the respiratory surface. They are moist and one-cell thick and are surrounded by capillaries for call exchange. That's about it :)
