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>

You must know rour resting heart rate before you can calculate your target heart rate for exercise. Correct answer: B Resting heart rate is the number of times the heart beats per minute when te body is at rest. It is usually somewhere between 60 and 100 beats per minute for the average adult. In order to calculate the target heat rate, you should calculate heart rate reserve (HRR) which is resting heart rate subtracted from your maximum heart rate. Then you should m
ultiply your HRR by 0.7 (70 percent) and add your resting heart rate to this number and ultiply your HRR by 0.85 (85 percent) and add your resting heart rate to this number. This is the taregt zone.
