It doesn't matter. The only thing you need to show is that the X amount on your payslip is deposited as X amount on your bank statement each month. That's all that UKVI need to see.
The only thing that you would need to explain is if you got a sudden large deposit into or made a large transfer out of your account (i.e. thousands of pounds in one go), because it could look like something dodgy is going on... so, you might want to explain the bank loan (i.e. what it's for), but you wouldn't need to explain the other transfers.
