// Dr. Pilloff is trying to explain the circulatory system
Dr. Pilloff: So when you get cut, it's always your veins that get cut. If you cut an artery, then you die.
Student: But isn't the blood in your veins blue? Why is your blood red when you bleed?
Dr. Pilloff: It reacts with the oxygen in the air.
Class: Ohhhh.
Dr. Pilloff: But what you could do is go into a room with no oxygen, hold your breath and cut yourself. Then your blood would come out blue.
