What is the difference between Retesting and Regression Testing?

Regression Testing:
It is a process where the tester ensures that the software is satisfying the requirements on each and every release. Here the testing is done on already tested functionality and making sure it works now also.

Retesting:
It is a verification process where the tester makes sure that the defect which was marked as fixed by the developer is working as expected, so as to close it.
