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>
This activity requires students to drag organs of different body systems into the human body cartoon (Arnold) classifying them according to certain systems (digestive, skeletal, circulatory/respiratory, and nervous).
6mg per Kg
115 lb = 52.16kg
if 6 mg per 1 kg, to find for 52.16 kg, you multiply by 52.16 = 312.9mg
SO for 115 lb person = 312.9 mg
