heart, lung, kidney, skin
Organs and tissues successfully transplanted since 1950 include the heart, liver, kidneys, lungs, pancreas, and corneas. Currently, the most commonly transplanted organs are the kidneys and livers due to the high demand for these organs and the success rates of the procedures.
Liver, heart, pancreas, lungs, and faces if you count skin.
Hearts, liver, kidneys, lungs, small intestine, pancreas, corneas, heart valves. Some other things have been transplanted (both successfully and unsuccessfully), but typically only "life saving" organs are routinely transplanted.
since an organ is made of multiple tissues, the organ will have all the specialized cells of multiple tissues. As a result, the organ will have more.

Just to clarify your question, if the organ cannot be transplanted there is no "recipient", since nobody receives the organ. The brain is not transplantable in humans. It has been performed in labs on animals, with mixed outcomes. However in humans it is unclear whether there are any medical conditions which would actually benefit from a 'brain transplant', let alone other ethical questions of performing such a procedure. The large intestine is not commonly transplanted because it is not necessary to sustain life (however it is medically possible). Likewise, the stomach, gall-bladder and appendix are not necessary for survival.
Heart, lungs, liver, kidneys, and pancreas can all be successfully transplanted from one person to another. Transplants of these organs can greatly improve the recipient's quality of life and even save their life in some cases. Organ transplantation is a complex medical procedure that requires careful matching of donor and recipient and lifelong follow-up care.
Cells are the smallest unit of life. Large groups of cells with the same purpose are called tissue, groups of tissue with the same purpose form organs, organs with similar purposes form systems and systems form organisms.
A cell is the smallest object that can perform life's functions. Tissues are made up of two or more cells working towards a single function. An organ is made up of two or more tissues working together to perform another function.
There is no transplant for Crohn's disease. (The large intestine is never transplanted since you can live without it. The small intestine can be transplanted, but it does not cure Crohn's disease).
There are not 2 main organs in a human body. I can think of about 7 organs without witch you would not survive for long. But since you put question that way, I guess the most natural response would be brain and heart (although without lungs your brain would not have must use). The function of the heart is to circulate the blood around your body, to supply oxygen and many more chemicals to all your organs and tissues. The function of the brain is to coordinate your nervous system.
