Irritant receptors lie betw
Irritant receptors in more peripheral bronchi are insensitive to mechanical irritants, but they are sensitive to chemical stimuli; the pattern is reversed in the central airways. Reflex effects include bronchoconstriction and hyperpnoea.
Irritant receptors are also sensitive to histamine and can thus contribute to the bronchoconstrictor response in asthmatic subjects in whom histamine is released from mast cells or other cells.
een airway epithelial cells. They are stimulated by mechanical stimuli, inhaled dusts, cold air, noxious gases and cigarette smoke. The receptors show rapid adaptation when they are continuously stimulated. Impulses travel via myelinated fibers in the vagus nerve.
Irritant receptors are also sensitive to histamine and can thus contribute to the bronchoconstrictor response in asthmatic subjects in whom histamine is released from mast cells or other cells.
What else can I help you with?
What three kind of reflexes are involved in the regulation of repiration?
Respiration in itself is a kind of reflex; we do it involuntarily. However, it can be impeded with different oxygen concentrations in the air, drugs, and other reflexes like sneezing, burping, or coughing.
Dilation and relaxation of the bronchioles are possible bcause of the presence of?
Beta 2 adrenergic receptors in lung tissue cause dilation of bronchioles via sympathetic stimulation.
True or false Sympathetic stimulation of the lung results in broncoconstriction?
false
What does lung hyperinflation stimulate?
Lung hyperinflation stimulates pulmonary stretch receptors. A person who experience lung hyperinflation can end up having COPD or chronic obstructive pulmonary disease.
How can the spread of emphysema be controlled?
Emphysema does not "spread"-- it is NOT contagious.However, the incidence of emphysema can be reduced if all countries and persons reduce lung irritants and air pollution. ANY strong chemical is a lung irritant. Smoking is just one of a long list of lung irritants.
What gases were used in World War 1?
1) Xylyl bromide-Lachrymatory, toxic 2) Chlorine - Corrosive. Lung Irritant 3) Phosgene - Irritant - Skin and mucous membranes. Corrosive, toxic 4) Benzyl bromide - Lachrymatory (lacrimatory: relating to or prompting tears) 5) Chloromethyl chloroformate - Irritant - Eyes, skin, lungs 6) Trichloromethyl chloroformate- Severe irritant, causes burns 7) Chloropicrin - Irritant, lachrymatory, toxic 8) Stannic chloride -Severe irritant, causes burns 9) Ethyl iodoacetate-Lachrymatory, toxic 10) Bromoacetone-Lachrymatory, irritant 11) Monobromomethyl ethyl ketone- Lachrymatory, irritant 12) Acrolein-Lachrymatory, toxic 13) Hydrogen cyanide (Prussic acid)-Toxic, Chemical Asphyxiant (Asphyxiant-Gas or vapor that can cause unconsciousness or death by suffocation due to lack of oxygen.) 14) Hydrogen sulfide (Sulphuretted hydrogen)-Irritant, toxic 15) Diphenylchloroarsine-(Diphenyl chlorasine)-Irritant/Sternutatory (Sternutatory-causing or having the effect of sneezing) 16) A-Chlorotoluene (Benzyl chloride) - Irritant, lachrymatory 17) Mustard gas (Bis(2-chloroethyl) sulfide)-Vesicant (blistering agent), lung irritant 18) Bis(chloromethyl) ether (Dichloromethyl ether)-Irritant, can blur vision 19) Ethyldichloroarsine-Vesicant-a chemical agent that causes blistering 20) N-Ethylcarbazole- irritant
What different types of lung conditions was found as a result of 9 11 attack?
what different types of lung conditions was found as a result of 911 attavck
What is an abnormal result of a lung ventilation scan?
absence of marker material when the lung perfusion scan for the area is normal suggests lung disease
How far can a lung stretch?
For an adult male, the most a lung can hold is about 6 liters of air. There is a reflex in the body that will prevent overstretching of the lungs. This is called the Hering–Breuer inflation reflex which is triggered by receptors on the surface of the lung and carried via the Vagus nerve.
What can Keratinization of lung cells may result from?
toxicity of vitamin A
Why should ammonia and bleach be stored separately in your home?
When mixed together, ammonia and bleach form chlorine gas which is harmful for lung, or at least concentration irritant for eyes, airways, skin etc...
What happens to lung capacity as a result of long term training?
Increases
