Q. does mosquito bites considered as an edema

a bet with a friend- please help solve an issue an help me win a new I pod :)
A1(don't take the mini i-pod, it sucks). it's true-the mosquito has a number of proteins and materials in his saliva that works as anticoagulants and vasodilators (blood vessel broadening). these causes the bite area to start an immune reaction and one of the consequences is an edema-"an increase of interstitial fluid in any organ", that means fluids are exiting blood system. in this case- not too much...
A2i hope you said it is :). edema is a normal reaction to an inflammation, which is-your body reaction to any thing unfamiliar to it. the mosquito injects a substance that makes our body react and recruit the immune system to the area. that means swelling up and get a red/pink color because of blood vessels broadening and blood cells coming out.

Q. what is "pulmonary edema" and what are the risks?

my Dr. told me I'm in a risk group for pulmonary edema, he tried to explain what it is but i didn't understand fully...if someone may give me a brief explanation- I'll appreciate it!
A1pulmonary edema occurs when, lets say, your heart left ventricle stops working properly and your right ventricle works fine. that means your lungs getting lets presume- 1 liter of blood -but your left ventricle can pump out of it only 990 ml. that means you have high blood pressure in your lungs and fluid comes out of blood vessels and fills your lungs, making it harder and harder breathing.
A2edema is a situation of fluids getting out of your cells or blood to your extra cellular matrix and organs. pulmonary edema is when your lungs fills with fluids originated from your blood. hence the main risk is actually drowning. this is a life threatening situation that requires a medical help A.S.A.P.
