The cells most responsible for the rejection of a transplanted organ, such as a heart, are T cells.

Here's a step-by-step explanation:

1. When a new organ is transplanted, the immune system recognizes it as foreign. This is because the immune cells, specifically T cells, can identify proteins on the cells of the transplanted organ that are different from the proteins on the recipient's own cells.

2. T cells are a type of white blood cell that play a key role in the immune response. They are responsible for cell-mediated immunity, which is the part of the immune system that rejects foreign tissue.

3. Once the T cells recognize the transplanted organ as foreign, they begin to attack it. This is what leads to organ rejection.

4. Other immune cells, such as B cells, macrophages, and eosinophils, can also play a role in organ rejection. However, T cells are generally considered the most responsible because of their role in cell-mediated immunity.
