Morphology

rejection = reject (transparent) = re + ject + ion

This is a standard noun formation from the verb 'reject', and the medical sense directly means the body's act of rejecting transplanted material.

Etymology

Rejection comes from Latin parts re- meaning 'back' and -ject meaning 'to throw', the same -ject you see in eject and project. In medicine, a rejected organ is like something the body 'throws back' or will not accept, which is why doctors call it a 'rejection'.
