Textbook Question
Chapter 36, Problem 2CT
An atrial septal defect is a birth defect in which there is an opening in the septum between the left and right atria. People with such a defect typically have more than a normal amount of blood in the right atrium. Why does blood flow from left to right across the septum rather than in the opposite direction? The excess of blood can cause hypertension in one circuit. Which one?
