The main purpose of this study is to analyze pre-service elementary teachers’ understanding of the human heart, the blood vessels (arteries and veins) connected to the heart, and the blood (arterial blood and venous blood) flows inside it. The main findings of this study were as follows: 1) About 30% of the students were able to explain the terms arteries and veins scientifically and correctly, and the students’ ideas could be classified into five types. 2) For three groups, we presented drawings related to the human heart and the blood vessels connected to the heart with different information. In addition, we pointed out the arteries and veins in the drawing. We quizzed the students, and the number of complete correct answers were about 30% to 70% in each group. 3) About 55% to 85% in each group had scientifically recognized the nature of the blood (arterial blood and venous blood) flowing inside the heart and the blood vessels connected to the heart.
