What function of the smooth muscle that the structure complements or ensures?
smooth muscle:a) has a fusiform shapeb) allows the muscle to tense and relax.
What is the function smooth muscle tissue in your stomach?
Digestive organs
What is the main function of smooth muscle cells?
involuntary muscle movements
Are smooth muscles striated or smooth?
Smooth muscle is the muscle inside of the digestive system so it has to be involuntary.
Muscle tissue that shows no striations?
Smooth Muscle
What muscle controls the size of the bronchioles in the lungs?
SmooTh muscle
What part of the respiratory tree has the largest proportion of smooth muscle?
Bronchioles
What is an example of a smooth involuntary muscle?
ones that line the walls of the trachea and bronchioles
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.
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.
What small structures located within the bronchial tree are composed primarily of smooth muscle?
Bronchioles are smaller tube divisions of bronchi. Walls of bronchioles contain smooth muscle and no cartilage. This helps in contraction and relaxation which allows the flow of air to alveoli.
What is the medical term meaning contraction of the smooth muscle in the walls of the bronchi and bronchioles that tighten and squeeze the airway shut?
Bronchoconstriction or bronchospasm is the medical term that refers to the contraction of the smooth muscle in the walls of the bronchi and bronchioles that tighten and squeeze the airway shut.
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.
How does a inhaler affect the muscle around the bronchioles?
it reduces the swelling
Does the respiratory system have smooth muscles that surrounds the bronchioles?
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.
Is a principal function of smooth muscle peristalsis?
Yes
What is the function of the smooth muscle cell?
I hate school
