Answer:
Bronchoconstriction may be defined as the constriction of the lung airways that might occur due to the tightening of the smooth muscle. This might result in the sneezing and coughing.
The anti - inflammatory drugs are taken against the symptoms of the constriction. These drugs causes the relaxation of the airways and also result in the decrease of the airway hyper reactions with the different stimuli that might result in the constriction symptoms.
<span>not move since their is an equal concentration between the two sides.
Diffusion
occurs because of the movement of molecules from the region of higher
concentration to the region of lower concentration. This movement of
molecules occurs due to a thermal motion. Diffusion normally occurs
between two compartments having difference in concentration. In case of
fluid it moves from the region of higher concentration to the region of
concentration until a balance is reached. The process of diffusion is
very important for the humans as well. The oxygen that humans breathe in
gets diffused with the blood.<span>
