Blood In Your Veins Is Blue, And Blood In Your Arteries Are Red
This is another commonly believed myth passed as fact. The brightly colored diagram of the blood circulation system also didn’t help. A large part of the myth says the blood is blue inside the body, but it becomes red when it comes out of the body and is exposed to oxygen.
Your blood is red unless you’re an alien from a sci-fi movie. The blood is red due to the presence of hemoglobin. Hemoglobins are carried in the blood and function in the transportation of oxygen. Hemoglobins are iron-rich and red.
