In brief: See below

To perform hemodialysis blood needs to pass through a artificial kidney or membrane in a hemodialysis machine.
A fairly large volume needs to pass trough the machine and recirculated back to the patient to be an efffective way to "clean" the blood of waste. A large vein needs to be canulated and a large size IV plastic tube needs to inserted into a vein in the neck or groin.

In brief: Get and return blood

Hemodialysis requires blood to be drawn from the body, go through the machine to filter out waste products and then return it back to the body.
These machines require a high flow of about 400 cc per minute so need either an arterio venous fistula or a catheter in a large vein if dialysis is needed immediately.
