  1. A measurement of radioactivity

  2. A tube for insertion into the body

  3. A device to monitor vital signs

The correct answer is: A tube for insertion into the body

A cannula serves the primary function of being a tube designed for insertion into the body. This device is commonly used in medical and dental settings to deliver liquids or gases, such as medication or anesthetics, directly into a patient’s bloodstream or to allow access for various medical procedures. The versatility of cannulas makes them essential tools in a wide range of applications, from intravenous therapies to respiratory support. Their design facilitates the passage of fluids while minimizing discomfort and potential injury to the surrounding tissues.
