Step-by-step explanation:
The type of syringe that is calibrated in units is the insulin syringe. Insulin syringes are specifically designed to measure and administer insulin, a hormone used to treat diabetes. They are calibrated in units to ensure accurate dosing of insulin.Insulin syringes typically have a volume of 1 mL and are marked with units, such as 50 units/mL or 100 units/mL.
