Why can twins resulting from a single fertilized egg exchange blood or receive organ transplant from each other without rejection while twins resulting from two fertilized eggs sometimes cannot?

Twins resulting from one single fertilized egg carry exactly the same DNA. They are exact copies of each other (medically, anyway). Twins from two different eggs, although are twins, do not share the same DNA (since each egg carries different genes), hence are not completely compatible for organ transplantation (without additional immunosuppression).

Yes, it is not common, but host-graft rejection sometimes leads to an overwhelming immunologic reaction - against your own body - and this can be fatal, if untreated.

Why is it important for immune system cells to be able to recognize all of the body's own cells?
This happens to my Mom sometimes. When she's really stressed, tired, sick, etc; her immune system starts attacking her body again. I don't know why, it just does. It happened with her immune system or something like that and also her eyes. The immune System needs to know what is friendly and a threat to the brain & body. Although it has trouble sometimes when you get a transplant and the shape/size/composition/etc isn't similar enough to your own.
Does selenium help with high cholesterol and thyroid gland?
In some cases, supplementation of selenomethionine (a type of selenium) may result in better conversion of T4 to T3, sometimes resulting in lowered cholesterol levels and raised thyroid levels within the body. In some cases selenomethionine supplementation can result in the remission of Hashimoto's thyroiditis.

Why do females make twins?
There are a couple of ways that multiples are conceived: 1) Multiple eggs are released or there is more than one ovulation. Two eggs are fertilized and you have fraternal twins. This can happen with or without fertility drugs. 2) One egg is fertilized and then splits in two resulting in identical twins. This can happen with or without fertility drugs. 3) In cases of in vitro fertilization (IVF), 3 or more fertilized eggs are put back into the uterus. The rationale is that not all of these will implant, though sometimes they do.
Why are kidney transplants good?
Yes and No, because my cousin died from a kidney transplant. Sometimes your body doesnt adjust to your new kidney and sometimes it doesnt match your kidney you already have. So you should ask your local doctor about the kidney transplant. Sincerely,Tjones23

Why is there a market for organ transplant tourism?
The simplistic explanation is because there are not enough organs or facilities in the person's home country to guarantee that they can be transplanted safely. Sometimes being able to afford a transplant is also an issue, in which case going abroad for a transplant may prove cheaper.

Does egg implant assures pregnancy?
no pregnancies fail for many reasons. sometimes after eggs are fertilized they don't attach to the uterine wall, sometimes they do attach but develop an abnormality and the body aborts them, sometimes after the fertilized egg starts traveling down the fallopian tubes the fertilized egg prematurely attaches to the tubes and ectopic pregnancy develops (which leads to spontaneos abortions), sometimes they cant attach because of abnormalities in the uterine wall itself (like if a woman has endometriosis), sometimes trauma to the reproductive organs can cause damage to the embryo and that can cause the body to abort the child.
