Lesson: The Heart Biology • Second Year of Secondary School

Students will be able to

• recall the location of the heart in the human body as being fairly central in the chest cavity and encased by ribs for protection,
• describe the basic structure of the heart including the ventricles, atria, valves, and connected blood vessels of pulmonary vein/artery, vena cava, and aorta,
• outline the route the blood takes through the heart and around the body,
• explain how the different structures of the heart aid its function, including the cardiac muscle, the valves (bicuspid, tricuspid, and semilunar), and the associated blood vessels,
• use the equation cardiac output = heart rate stroke volume to complete simple calculations.
