Description:This image depicts a close view of the distal tip of an empty syringe revealing the metallic needle with its blue plastic proximal end that attached the needle to the syringe barrel. In the bright red background, though out of focus, you can still make out the universal biohazard symbol. The barrel is calibrated, however, it is not known what the calibrated tic marks represented, as to their measurement.
The syringe and needle is a very efficient method for delivering medications and vaccines into an organism in a parenteral manner, which includes humans as well as animals. Injections can be delivered intravenously, i.e., into a vein, arterially, i.e., into an artery, subcutaneously, i.e., under the surface of the skin, and intramuscularly, i.e, into a muscle, just to name a few of the more common routes of administration.
