What is a "needle"?
A needle is a thin and pointed medical tool used to pierce the skin for various purposes, such as injecting medications, drawing blood for tests, or delivering fluids directly into veins or tissues. Needles are typically made of stainless steel and come in different sizes depending on their use. They are essential in medical procedures for giving treatments and getting samples for diagnosing patients, while causing minimal discomfort.
