Injection in general is a type of medical procedure of introducing a fluid into the patient's body. The infusion of the liquid in to the body governs certain actors such as the depth, amount, location and need. Injections are usually administered in order to direct the drug to its function rather than through the digestive tract. 

There are different kinds of drugs based on its effectivity. Injecting the drug to a specific location in the body is done in order for the function of the drug be maximized. If the medical person injects a drug to wrong location, the drug may not be utilized well and can even produce side effects in the patient. 

There are different kinds of injections depending on the medical needs of the patients. Injections are classified to the depth infusion. This includes:

  • Intradermal - layers of the skin (for allergy treatment, anti-tetanus, tuberculosis)
  • Intramuscular - direct infusion to the muscle for rapid absorption of the medicine (Vaccines and hormones).
  • Subcutaneous injections - when medicine should be absorbed slowly. 
  • Intravenous - directly to the veins 

Some injections like anaesthesia are infused directly to where it is needed (e.g. tooth extraction, surgery or amputations).
