Document Summary

Functions so supply the body with oxygen and dispose carbon dioxide. Movement of air into and out of the lungs so that gases there are continuously changed and refreshed (i. e. : breathing: external respiration. Movement of oxygen from the lungs to the blood and of carbon dioxide from the blood to the lungs: transport of respiratory gases. Transport of oxygen from the lungs to tissue cells of the body. Transport of carbon dioxide from the tissue cells to the lungs. Accomplished by the cardiovascular system using blood as the transporting fluid: internal respiration. Movement of oxygen from blood to the tissue cells. Movement of carbon dioxide from tissue cells to the blood. The first 2 functions are the specialty of the respiratory system and functions 3 and 4 involve the cardiovascular system. Respiratory system includes the nose, nasal cavity, paranasal sinuses, the pharynx, the larynx, the trachea, the bronchi and their smaller branches, the lungs, and alveoli.

Oxygen in the Lungs: In the lungs, the respiratorymembraneseparates tiny sacs of air (pressure1.00x105Pa) from theblood in the capillaries. These sacs are called alveoli. Theaverage radius of thealveoli is 0.125 mm, and the air insidecontains 14% oxygen. Assuming that the air behaves as an ideal gasat 310 K, find thenumber of oxygen molecules in one of thesesacs.

Long-term space missions require reclamation of the oxygen in the carbon dioxide exhaled by the crew. In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen and 1.00 mol of methane as a byproduct. The methane is stored in a tank under pressure and is available to control the attitude of the spacecraft by controlled venting. A single astronaut exhales 1.09 kg of carbon dioxide each day. If the methane generated in the respiration recycling of three astronauts during one week of flight is stored in an originally empty 160 L tank at -36.0°C, what is the final pressure in the tank?

The radioactive isotope ^{133}_{\ 54}\rm Xe is used in pulmonaryrespiratory studies to image the blood flow and the air reachingthe lungs. The half-life of this isotope is 5 \rm days.

a. A hospital needs 0.100 \rm g of ^{133}_{\ 54}\rm Xe for alung-imaging test. If it takes 10 \rm days to receive the shipment,what is the minimal amount m_Xe of xenon that the hospital shouldorder?
