<human>: I've always wondered how a syringe is made. Is it just some type of plastic?
<bot>: A syringe is basically a hollow tube that can be used to inject fluids into the body. It is typically made from a medical-grade plastic, such as polypropylene or polyethylene. The inside of the syringe is usually lined with a material called latex rubber, which is used to help keep the needle sterile and prevent leakage.
