syringe needles

Syringe needles are slender, hollow tubes attached to syringes used to inject fluids into or withdraw fluids from the body. Made from metal or plastic, they come in various sizes and gauges, which determine their thickness and the amount of fluid they can handle. The needle's sharp tip allows for smooth penetration of skin or other tissues, minimizing discomfort. Needle design also includes features like bevels (the slanted tip) for easier insertion and safety features to prevent accidental injuries. Proper use and disposal of needles are essential to ensure safety and prevent infections.
