The size of the syringe determines the interval range of the measurement calibrations on the barrel. Larger syringes have larger intervals between graduation lines. One end of the barrel tapers into a hollow opening that forms the tip, which articulates with the needle. The plunger connects to the open end of the barrel using a slightly cone-shaped top, explains UNC Eshelman School of Pharmacy.
