Answer:
The statement that is true about leukotrienes is that they create excess mucus in the airways (last option).
Explanation:
Leukotrienes are inflammatory mediators, derived from arachidonic acid, in whose presence occurs increased vascular permeability in tissues, leading to inflammatory processes.
The presence of leukotrienes has been related to the development of allergic reactions, mainly in the respiratory tract, producing edema in the mucosa, contraction of the smooth muscles of the airways and increased production of mucus
in the airways.
the other options are not correct because leukotrienes:
- <em>Produce contraction of the smooth musculature around the airway.
</em>
- <em>Are related to the production of bronchial asthma.
</em>
- <em>Are inflammatory (chemical) mediators. </em>
