The diameter of the airway is the most important factor in determining airway resistance. A smaller diameter increases resistance, making it harder for air to flow. Factors such as mucus, inflammation, and constriction can also affect airway resistance.
Buteyko, also called the Buteyko method, is an asthma management method based on breathing exercises that reduce airway constriction
efferent arteriolar constriction.
It entirely depends on what is in the nasal spray. If it is saline spray, then it doesn't really do anything to the capillaries per se. If it is a decongestant then it causes constriction of the capillaries (which will tend to open up the nasal airway). If it is H1N1 influenza spray, then it uses your capillaries to deliver virus to the rest of your body.

Food stuck in the esophagus is blocking your airway. If your airway is blocked, no air can get into your lung, thus causing breathing difficulties.
with stimulation of the sympathetic nervous system there will be a. constriction of the pupils b. dilation of the coronary arteries c. constriction of selected blood vessels d. profuse sweating
How about cocaine. It causes vaso-constriction of blood vessels in your body including vessels in your heart, which can result in a heart attack.
There are no nerves located within the lungs themselves. However, the lungs are innervated by the pulmonary plexus, which consists of autonomic nerves that regulate functions such as breathing, blood flow, and airway constriction.
Administration of a miotic agent causes constriction of the pupil. Miotic agents work by stimulating the muscles in the iris to contract, resulting in a smaller pupil size. This can be useful in treating conditions such as glaucoma or to help improve vision after cataract surgery.
There will be no systolic sound if blood is flowing freely. This occurs when there is no measurable constriction of an artery.
not entirely sure, but I think it can be constriction, inflammation, or mucus (or probably any combination of the three)
