During inspiration, the volume of the lungs is actively increased by the action of the diaphragm. Asthe volume of the lungs increases, the pressure within the lungs falls about 1 mmHg belowatmospheric pressure. Air rushes into the lungs due to this pressure difference.Bronchi, Bronchial Tree, and LungsLarynxPrimary bronchiSecondary bronchiTertiary bronchiBronchiolesCardiac notchPulmonary arteryTracheaPulmonary veinAlveolar ductAlveoliThis image is part of the Public Domain: https://upload.wikimedia.org/wikipedia/commons/d/db/Illu_bronchi lungs.jpgFig. 1: The bronchi, bronchial trees, and the lungs.(a) The diameter of the trachea (windpipe) is about 17 mm.

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, with 1.00 mol of methane as a by-product. 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 1,08 kg of carbon dioxide each day. If the methane generated in the recycling of three astronauts' respiration during one week of flight is stored in an originally empty 165-L tank at -45.0°C, what is the final pressure in the tank?

Snorkelers breathe through short tubular "snorkels" while swimming under water very near the surface. One end of the snorkel attaches to the snorkeler's mouth while the other end protrudes above the water's surface. Unfortunately, snorkels cannot support breathing to any great depth: it is said that a typical snorkeler below a water depth of only about 30 cm cannot draw a breath through a snorkel. Part A Based on this claim, what is the approximate fractional change in a typical person's lung volume when drawing a breath? Assume, in equilibrium, the air pressure in a snorkeler's lungs matches that of the surrounding water pressure. Express your answer using two significant figures. AV % Vrelaxed Submit Request Answer
When you exhale, all of the air in your lungs must exit through the trachea. If you exhale through your nose, this air subsequently leaves through your nostrils. The area of your nostrils is less than that of your trachea. How does the speed of the air in the trachea compare to that in the nostrils?
Which is not a reason why the blood pressure meter cuff is placed in the left arm? Choices: Because it has the same pressure as the heart since it belongs to the same horizontal Because it has the brachial artery which pulse is comparable to the heart Because it is nearest to the heart compared to other parts Because it is the most convenient part of the patient

Inthelungs,therespiratorymembraneseparatestinysacsofair(absolute pressure=1.00x105 Pa) from the blood in the capillaries. These sacs are called alveoli, and it is from them that oxygen enters the blood. The average radius of the alveoli is 0.125 mm, and the air inside contains 14% oxygen, which is somewhat smaller amount than in fresh air. Assuming that the air behaves as an ideal gas at body temperature (310 K), find the number of oxygen molecules in one of the sacs.

Scuba divers are warned that if they must make a rapid ascent, they should exhale on the way up. If a diver rapidly ascends to the surface with lungs full of air, his lungs could be damaged. Explain why this is so.
