AP Biology

This lesson explores the structure and function of the mammalian circulatory system, focusing on the pumps, vessels, and valves involved. Topics include blood flow to the lungs, the role of the right and left ventricles, the pulmonary vein and aorta, the amount of CO2 in different parts of the system, and the prevention of backflow. Additionally, students will learn about the "Lub" and "Dup" sounds heard using stethoscopes. The lesson will include quizzes, lectures, games, and slides on the circulatory system.
