How is breathing affected if smooth muscle of the bronchial contracts?
Wiki User
∙ 10y ago
When the smooth muscle of the bronchial tree contracts it creates a high resistance to the air flow into the lungs. Breathing is affected since the balance of oxygen and carbon monoxide is off, causing a higher respiration rate.

What is an adjective that means pertaining to the diaphragm?
Diaphragmatic. The diaphragm, in human anatomy, is the relatively thin, curved muscle that contracts and relaxes in the work of breathing.
What kind of tissue contracts?
Muscle tissue specializes in contraction. This includes cardiac, smooth, and striated.
If a muscle contracts and its fibers shorten is the contraction isometric?
No! It is isotonic. But if the muscle contracts and the fibers do not shorten because the load is greater than the force applied to it, it is isometric.
What is the deep muscle of the thorax that promote the inspiratory phase of breathing?
The deep muscle of the thorax that promote the inspiratory phase of breathing is the external intercostal. It is a muscle that originates from the lower border of a rib.
What is the job of the diaphram?
The major muscle that the body uses for breathing The above answer is of course correct for the thoracic diaphragm but there are others for example the pelvic diaphragm. A diaphragm is a domed muscular wall the reperates to regions. When is contracts it flattens to increase pressure on the inside of the dome and decrease pressure on the outside of the dome. In the case of the pelvic diaphragm is domes downards and contracts to resisf the increased pressure from the thoracic diaphragm on the abdomen during inhalation.
How is breathing affected if smooth muscle of bronchial trees relax?
When the bronchial tree relaxes, more oxygen is taken into the body and more carbon dioxide is expelled from the body.
What is the large breathing muscle that contracts to create a vacuum drawing air into the nose and mouth?
Your lungs are the largest breathing muscle in your body.
Which muscle contracts aiding the process of breathing?
The diaphragm - a sheet of muscle across the rib-cage just under the lungs.
What muscle separates the thorax and abdomen and aids in breathing?
The muscle that separates the thorax and abdomen and aids in breathing is called the diaphragm. It is a dome-shaped muscle that contracts and relaxes to regulate the volume of the thoracic cavity, allowing for inhalation and exhalation.
What does a muscle become when it contracts?
A muscle becomes shorter when it contracts.
When a muscle contracts how does its form change?
A muscle that contracts shortens whereas a muscle that relaxes lengthens.
What is an adjective that means pertaining to the diaphragm?
Diaphragmatic. The diaphragm, in human anatomy, is the relatively thin, curved muscle that contracts and relaxes in the work of breathing.
Muscle that controls breathing as it contracts and relaxes?
The Diaphragm - a membrane of muscle and tendon, flexes to reduce ambient pressure in the thorax, and cause the lungs to compensate by drawing in air. Exhalation works in reverse.
Deep muscle of the thorax that promote the inspiratory phase of breathing?
The deep thorax muscles are the deep muscles of the thorax that promotes the inspiratory phase of breathing. When breathing the diaphragm contracts, producing a negative pressure, which forces are into the lungs.
What is a muscle that is associated with breathing?
The diaphragm. It is the only muscle that causes breathing.
When one muscle contracts what happens to the opposing muscle?
When one muscle in a pair contracts the other expands.
What conditions cause contractions of arteriole smooth muscle?
Asthma causes contraction of the bronchial smooth muscle.
