The act of blowing air or a substance into a body cavity, often used in medical or ceremonial contexts.
The doctor performed an insufflation to deliver the medication directly into the patient's lungs.
Insufflation is formed from "in-" (meaning into) and "sufflare" (meaning to blow). The word describes the act of blowing air or gas into a space, particularly in a medical context.
Think of 'blowing air into' ('sufflare') something, which helps you remember that insufflation means to blow air into a space.
