Module 8—Circulation, Immunity, and Excretion

Reflect and Connect

Your body is incredibly efficient at filtering blood. The sheer volume of blood filtered by the kidneys is extraordinary considering that a kidney is the size of a conventional computer mouse.

Water treatment plants in Edmonton produce about 530 million litres of filtered water every day. To put your kidneys in perspective, think of this: Water treatment plants service approximately 1 million people. This means that 530 L of water is filtered per person per day.

Water treatment plants are huge. Your kidneys, each the size of a computer mouse, process 180 L blood per day for one person. This size difference illustrates the efficiency of your body to filter blood and create urine. Complete the following questions to test your knowledge.
