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.
What else can I help you with?
What part of the respiratory tree has the largest proportion of smooth muscle?
Bronchioles
What type of pharmacology is used to relax the smooth muscles of the bronchioles?
Bronchodilators
What are 3 places smooth muscles can be found?
Smooth muscles can be found in the walls of blood vessels, the digestive tract, and the respiratory system.
What is the functional importance of the decrease in cartilage and increase in smooth muscle in the lower respiratory passageways?
The smooth muscle in the walls of the bronchioles is very sensitive to the concentration of carbon dioxide. A rising level of CO2 causes the bronchioles to dilate. This lowers the resistance in the airways and thus increases the flow of air in and out.
What are three places where smooth muscles can be found?
Your blood vessels intestines bladder and other involuntarily controlled muscles are smooth muscles
What are the walls of the bronchioles made up of?
The walls of the bronchioles are made up of smooth muscle, connective tissue, and epithelial cells.
What muscle controls the size of the bronchioles in the lungs?
SmooTh muscle
What tiny cubes contain smooth muscle that can contract and relax thereby affecting the flow of air into the alveoli?
You do not have any such cubes in your respiratory system.
What is bronchioles filled with?
Bronchioles are approximately 1mm or less in diameter and their walls consist of ciliated cuboidal epithelium and a layer of smooth muscle.
Why would a disease that causes the paralysis of smooth muscles be a life-threatering disorder?
Smooth muscles are responsible for organ function, such as the lungs and intestines. If these muscles are paralyzed, it can lead to severe complications like respiratory failure or bowel obstruction, both of which can be life-threatening if not treated promptly.
How many smooth muscles are in the human body?
Smooth muscle tissue isn't divided into specific muscles like skeletal muscle tissue is, but these organs have smooth muscle in them: Stomach Small intestine Large intestine Iris (of the eye) Arrector pili (responsible for goosebumps) Ureters Bladder Parts of the esophagus Blood vessels Bronchi and bronchioles (the airways in the lungs) Uterus
The diameter of bronchioles can change because their walls contain?
Smooth Muscle tissue relaxation and contraction is responsible for dilation and constrictions of the bronchioles, respectively.
