Question

a severe allergic reaction can occur result in an unsafe drop in blood pressure. explain in terms of the immune response. why is the case.

Answer 1

Well with a severe allergic reaction or better known as anaphylaxis is all activated once the allergen has been initiated. It activates the immune cells and that is the beginning of the immune response. Once the cells are activated they then release a large amount of chemicals into the blood stream...such as histamine. The body's reactions then continue. The specific reaction you are searching for is a drop in blood pressure. Well, the response is that the blood vessels dilate and this is the response that leads to low blood pressure and a rapid hear rate. This is why it is so lethal too. It is important to have epinephrine handy to treat this cause.

Answer 2

Anaphylacsis, your throat slowly swells shut until it is completely closed. which slows blood flow to the heart as lung function begins to decrease thus causing blood pressure to drop due to lack of oxygenated cell flow. If allergic reaction is not stopped with medication tracheotomy these body functions will completely stop working and the person will die.
