The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
When a pathogen (disease-causing organism) invades the body, the neutrophils gather at the entry site and try to engulf it and destroy it.
A T helper cell will recognise only one pathogen. If the T helper cell recognises the invader, it will immediately clone to increase numbers.
After a few days of fighting off the pathogen, you will recover from your infection.
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>
These national working groups, in line with the international arrangement where focal points are selected for UNFF, will select national focal points representing the various Major Groups participating in the working group. I hope this helps you and good luck!
Answer: i’d say D. Permanent life insurance
Explanation: Homeowner’s insurance wouldn’t make too much sense since the daughter broke her arm and not anything concerning the house. Auto insurance is I think for cars so that wouldn’t work. The only reasonable one is d because something happened to her. I’m not too sure, but i think permanent life insurance has to do with someone’s life obviously. Hope that helps?
Option B would be your answer. The use of using steriods would then affect the form of the mens breast size. No facial hair will affect this, nor will a voice get deeper. It's only the breast that will be affected.
