Your heart does work to pump blood through your body. Each minute, 5.0 L of blood travels through your circulatory system. The pressure drops from 16 kPa as it exits the heart to approximately zero as it returns to the heart. We can calculate the work required to move a fluid volume V through a pressuredifference with a formula very similar to the one you saw for work in gases:a. What is the work done to pump the blood?b. What is the output power of the heart?
