Question 1

This question is about the circulatory system. Figure 1 shows the human heart. Which part of the heart receives oxygenated blood from the lungs?

Accepted Answer

Identify the four chambers of the heart. Remember that diagrams of the heart are shown as if you are looking at the person, so the left side of the diagram is the right side of the heart, and vice versa. Recall the path of blood flow: blood from the lungs is oxygenated and returns to the left side of the heart.

Question 2
