Q—my vs. the

Consider this—

I put the lightbulb in my biohazard trash and the tongs in the dishwasher

Now replace my's and the's with different combinations of my's and the's (or your's and her's)

I put my lightbulb in the biohazard trash and the tongs in the dishwasher
I put the lightbulb in the biohazard trash and the tongs in the dishwasher
I put your lightbulb in her biohazard trash and her tongs in my dishwasher

What is the effect of each?
