Answer:
Such injections (intramuscular injections) are supposed to go in the muscles and the buttocks and arms because the arm or buttocks have a good muscular bulk to receive these injections. These injections are not to go in the veins.
Explanation:
Intramuscular injections have other advantages too. The muscles have a plentiful supply of blood, which helps ensure that the body absorbs the medication quickly. The tissue in the muscles can also hold more medication than fatty tissue. Doctors administer most injectable vaccines into the muscles.
