Question
GCC 1: When fossil fuels are burned, "particulate matter" including some small particles referred to PM2.5S and even smaller particles can be produced. There was a recently published study showing how these small particles get into the bloodstream and-odge" in small blood vessels in the head and neck. 1A: What would you anticipate happening? If small particles enter the blood stream it can form a thrombus which can go to the head, neck or any other body parts creating a stroke or heart attack. IB: If this affeets blood vessels bringing blood to the heart, the person suffers from a heart attack due to the decreased blood flow to the heart tissue, this could lead to a person having Stroke. 1C: What kind of symptoms might occur if a blood vessel in the brain is blocked and oxygen does not get to that portion of the brain? Paralysis of one side of the body, vertigo, blurry vision or sudden visual loss, numbness of the fingers and difficulty speaking. 2a: This is a type of allergy which can be referred to as a Urticaria reaction which is restricted to a body surface. 2B: If an allergen enters the bloodstream, it can lead to more life-threatening conditions blood pressure to drop. 3a: What over the counter compound do some individ als take to decrease allergy symptoms? Claritin and Zyrtec This inhibits the effects of chemical released bycells. 3C: What category of antibody is particularly associated with allergy responses and how does the presence of these antibodies couple with the specific antigen (allergen) trigger an allergy response? IgE which is an antigen that functions especially in allergies. 4. It is not elearly stated in the book, but asthma and allergy responses are associated wit inflammation. 4A: What are the cardinal signs and symptoms of inflammation? Swelling, pain, warmth and redness.Explanation / Answer
Cardiac ischemia: Is a blockage of blood flow to the heart, this could lead to a person having strock. If the arteries are narrowed, less blood and oxygen reaches the heart muscle. This is also called coronary artery disease and coronary heart disease(heart attack).
Utricaria : also known as also known as hives, is a kind of allergic reaction showing skin rash with red, raised, itchy bumps.
Blood pressure drop in allergic reaction maybe due to histamine which is released by your body during an anaphylactic reaction causes blood vessels to widen which leads to a sudden and severe drop in blood pressure.
Zyrtec and Claritin are second-generation antihistamines used in treatment of allergic reactions, which reducess the histamine levels in blood hence the allergic simptoms. This inhibits the effects of histamine released by mast cells.
