What is the relationship between the pressures at label "3"? P outside + P inside P outside - P inside P outside < P inside P outside > P inside P outside = P inside

P outside > P inside

Boyle's law states that gas volume is inversely proportional to pressure. both directly proportional to pressure and directly proportional to temperature. directly proportional to temperature. inversely proportional to temperature. directly proportional to pressure.

inversely proportional to pressure.

Air moves out of the lungs when the pressure inside the lungs is less than the pressure in the atmosphere. greater than the pressure in the atmosphere. greater than intraalveolar pressure. equal to the pressure in the atmosphere. less than intrapulmonic pressure.

greater than the pressure in the atmosphere.

Major calyces are basic functional layers of the kidney. the expanded ends of renal pyramids. expanded ends of nephrons. large tributaries of the renal pelvis. conical structures that are located in the renal medulla.

large tributaries of the renal pelvis.

The function of pulmonary ventilation is to maintain adequate alveolar ventilation. supply oxygen to the blood. remove air from dead air space. remove carbon dioxide from the blood. prevent gas exchange in the bronchioles.

maintain adequate alveolar ventilation.

The filtrate first passes from the glomerular capsule to the collecting duct. distal convoluted tubule. proximal convoluted tubule. minor calyx. nephron loop.

proximal convoluted tubule.

The technical term for "breathing" is external respiration. alveolar ventilation. pulmonary ventilation. internal respiration. gas exchange.

pulmonary ventilation.

The glomerular capsule and the glomerulus make up the nephron loop. collecting tubule system. renal pyramid. renal papilla. renal corpuscle.

renal corpuscle.

Which of the following would be greater? the percent of oxygen saturation of hemoglobin when the pH is 7.6 the percent of oxygen saturation of hemoglobin when the pH is 7.2

the percent of oxygen saturation of hemoglobin when the pH is 7.6

When there is no air movement, the relationship between the intrapulmonary and atmospheric pressure is that atmospheric pressure is less than intrapulmonary. intrapulmonary pressure is greater than atmospheric. intrapulmonary pressure is less than atmospheric. atmospheric pressure is more than intrapulmonary. they are equal.

they are equal.

If a patient being tested inhales as deeply as possible and then exhales as much as possible, the volume of air expelled would be the patient's reserve volume. vital capacity. inspiratory reserve volume. tidal volume. expiratory reserve volume.

vital capacity.

What is the relationship between the pressures at label "8"? P outside + P inside P outside > P inside P outside - P inside P outside = P inside P outside < P inside

P outside < P inside

What happens to a carbon dioxide molecule once it enters the bloodstream? None of the answers is correct. It binds to the protein portion of hemoglobin molecules within red blood cells It dissolves in plasma It is converted to a molecule of carbonic acid All of the answers are correct.

All of the answers are correct.

A glomerulus is the middle segment of the renal tubule. the horseshoe-shaped segment of the nephron. a knot of capillaries within the renal corpuscle. the expanded end of a nephron. attached to the collecting duct.

a knot of capillaries within the renal corpuscle.
