The arterioles (small arteries) leading to an organ, constrict in order to decrease flow to the organ. To shut down an organ, blood flow is reduced naturally to 2.10% of its original value. By what factor did the radii of the arterioles constrict? Penguins do this when they stand on ice to reduce the blood flow to their feet.

- During inspiration, the volume of the lungs is actively increased by the action of the diaphragm. As the volume of the lungs increases, the pressure within the lungs falls about 1 mmHg below atmospheric pressure. Air rushes into the lungs due to this pressure difference.
