At rest, it takes approximately one minute for the blood to travel through the entire circulatory circuit. This is also known as the cardiac output, which is the amount of blood pumped by the heart per minute. The average cardiac output for an adult at rest is 5 liters per minute, and the total blood volume in the circulatory system is approximately 5 liters. Therefore, it takes one minute for all the blood in the body to circulate once through the heart and the blood vessels.
