        The Heart, Part 1: Under Pressure | Crash Course A&P 25

        Your heart gets a lot of attention from poets, songwriters, and storytellers, but today we'll learn how it really works. The heart's ventricles, atria, and valves create a pump that maintains both high and low pressure to circulate blood from the heart to the body through your arteries, and bring it back to the heart through your veins. You'll also learn what your blood pressure measurements mean when we talk about systolic and diastolic blood pressure.
