- 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 1.00% 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.arrow_forwardA major artery with a cross-sectional area of 1.00 cm2 branches into 18 smaller arteries, each with an average cross-sectional area of 0.400 cm2.

- 45. Insects do not have lungs as we do, nor do they breathe through their mouths. Instead, they have a system of tiny tubes, called tra- cheae, through which oxygen diffuses into their bodies. The tracheae begin at the surface of an insect's body and penetrate into the interior. Suppose that a trachea is 1.9 mm long with a cross-sectional area of 2.1 × 10-º m². The concentration of oxygen in the air outside the insect is 0.28 kg/m², and the diffusion constant is 1.1 × 10-5 m²/s. If the mass per second of oxygen diffusing through a trachea is 1.7 X 10-12 kg/s, find the oxygen concentra- tion at the interior end of the tube.arrow_forward9.
