Sometimes doctor inject medicines directly in our bloodstream, where do
they inject in artery or in vein?
Answers
Answer:
Almost all medications are injected into a vein. When we inject a medication (antibiotic, anesthetic, blood pressure control), the goal is to have that medication reach the entire body. When we inject it into a vein, the medication returns to the heart before reaching any of its targets, and the heart then pumps it to the entire body. While in the blood in the heart, the medication distributes evenly in the blood so there is a constant blood concentration of medication. If we inject a medicine into an artery, the medicine reaches only the parts of the body that receive blood from that artery. That would result in very high concentrations of medication in one place, but very low concentrations in the rest of the body. Sometimes, that’s the effect we want to achieve, so we inject into the artery (for example, if we want to see, for example, the foot’s portion of the arteries to plan surgery, we may inject the dye that lets us see the foot arteries into the artery that takes blood to the leg and the foot.)
