Pressure!. The blood in your veins are initially at a higher pressure and that spurt is the pressure equalizing!. The vacuum tube then sucks up the blood also because of pressure differences!.Www@Answer-Health@Com
The needle is in the vein, after the flash and return of blood they then push the tube onto the needle hub!.Www@Answer-Health@Com
because the needle is inserted where the blood from the vain is flowing towards so the blood flows through the needle!.Www@Answer-Health@Com
