Bronchioles. Bronchi, actually. Bronchioles are smaller and more numerous.
Air travels to and from the lungs though two branches of the trachea called bronchi (one branch equals bronchus; 2 is bronchi). The bronchi subdivide within the lobes of the lungs into smaller and smaller air vessels called bronchioles or bronchioli (singular), that terminate in alveoli. When the alveoli inflate with inhaled air brought in through the bronchi, oxygen enters into the blood. When air is exhaled through the bronchi, the alveoli deflate to expel carbon dioxide and other waste gases from the blood.
It has smooth muscles in order to support the lungs It is the role of cartilage to structurally support the trachea so it does not collapse in on itself (pulmonary atelectasis) during inspiration when the pressure in the lungs drops below atmospheric level. No that is wrong, smooth muscle is controlled subconsciously by the autonomic nervous system, and its function is to constrict or dilate, (by contracting or relaxing respectively), the airways to ease or restrict air flow through them. For example when you exercise, the smooth muscle will relax causing the diameter of the trachea to increase so more air can flow through them and hence allow a greater volume of oxygen to processed as needed by the body for respiration to release energy and provide this to the muscle cells during exercise. However, when one is surrounded by something which one is toxic such as a harmful gas, then the smooth muscle may contract and constrict the airways to reduce airflow and thus the amount of this toxic substance from entering the lungs and damaging the lung tissue.
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.
The alveoli is found at the end of each Bronchiole and Bronchi. The alveoli gets rid of all the carbon dioxide that is in our lungs.If you need more help just ask another question and I'll be free to answer it.
Foreign objects that enter the respiratory passageways are more likely to become lodged in the right primary (main) bronchus.
It is medication taken by an inhauler or hand held nebulizer which helps to open up the bronchi to help people who are having a difficult time with breathing. Most frequently seen in Asthma patients.
bronchi divides in primary bronchi . Which divides in secondary and tertiary.
You just said it. Here are much more sentences. The bronchi are large air tubes leading from the trachea to the lungs that convey air to and from the lungs. The bronchi have cartilage as part of their supporting wall structure. The trachea divides to form the right and left main bronchi which, in turn, divide to form thelobar, segmental, and finally the subsegmental bronchi.
When air enters your body, it passes through your nose or mouth, then travels down the trachea (windpipe), and finally reaches the lungs where gas exchange occurs. The lungs have smaller airways called bronchi and bronchioles where oxygen is absorbed into the bloodstream and carbon dioxide is released.
The trachea connects the larynx to the primary bronchi.tracheaThe Tracheathe trachea. it is a distal continuation of the larynx at the level of the sixth cervical vertebrae. the trachea then bifurcates into two principal bronchi at the level of the intervertebral disc between the fourth and fifth thoracic vertebrae.TracheatracheatracheatracheaThe trachea, more commonly known as the windpipe.the tracheaThe pharnyx? I'm guessing.The airway between larynx and bronchi is the trachea , or the windpipe.
dilates bronchioles so the person can breathe more easily
