First you must have a type and screen which determines your blood type. Then the blood get cross-matched to see if it is a good fit. There are many factors that must be considered before a person receives blood.
Of course in a trauma situation where there is no time to type, screen and cross match patients always receive Type O negative blood as this is the "Universal Donor."

If you receive a blood transfusion, you are under no obligation to "return" (or "donate") any blood to back the blood bank. This is true both before and after receiving a blood transfusion - i.e you do not have to have donated blood previously, before you can have a transfusion. (At least, this is how it works in the UK). Nice to know, really.
No, you can only receive your blood type when you get a blood transfusion.
No. Persons with type O blood can only receive type O blood.
A person with type B blood can only receive type B or O because it is said to be compatible and will not clump.
Catholics have no prohibitions about giving or receiving blood in a transfusion.
O negative can be given to a person with any bloodtype, but if possible it is better for a person requiring transfusion to be given blood matching their own bloodtype.
