And what is the difference between the Health Care FSA and the Dependent Care FSA?

The difference between a Health Care FSA and a Dependent Care FSA is that the Health Care FSA is for eligible health care expenses for you and your eligible dependents, and the Dependent Care FSA is for expenses related to the care of a dependent child or adult (for example, day care). The two are NOT interchangeable.
