Student: Hi, teacher! I was reading about the circulatory system, and I came across something intriguing. Why does a mere air bubble in the circulatory system prove to be fatal?

Teacher: Ah, that's a great question! The presence of an air bubble in the circulatory system can indeed have serious consequences. Let me explain.

Student: Thank you, teacher. Please do.

Teacher: Okay. You see, our circulatory system, which includes the heart and blood vessels, is responsible for carrying oxygen and nutrients throughout our body. If an air bubble enters this closed system, it can disrupt the flow of blood and create a condition known as an air embolism.
