Ch. 13 (Quiz 3)

QuestionAnswer
Henry's Law the mass of a gas that dissolves in a fluid at a given temp varies in direct proportion to the pressure of the gas over the liquid
2 factors that affect the rate of gas diffusion into a fluid: 1) the pressure differential between the gas above the fluid and the gas dissolved in the fluid2)the solubility of the gas
2 factors that impair gas transfer capacity at the pulmonary-capillary membrane in pulmonary disease: 1) buildup of a pollutant layer that thickens the alveolar membrane2) reduction in alveolar surface area
2 ways that blood carries oxygen: 1) in physical dilution dissolved in the fluid portion of blood2) loose combo with hemoglobin
cooperative binding union of oxygen with hemoglobin
oxyhemoglobin dissociation curve illustrates the saturation of hemoglobin with oxygen at various PO2 values
volume percent blood's oxygen content
oxygen transport cascade illustration that shows the oxygen partial pressure as oxygen moves from ambient air at sea level to the mitochondria of maximally active muscle tissue (pg. 284)
arteriovenous oxygen difference difference in the oxygen content of arterial blood and mixed venous blood
Bohr effect shifts in the dissociation curves of oxyhemoglobin due to any increase in plasma acidity and temp (curve shifts down and to the right...pg. 286)
3 ways that blood carries carbon dioxide: 1) in physical solution in plasma (small amount)2) combined with hemoglobin in red blood cells3) as plasma bicarbonate
carbonic anhydrase a zinc-containing enzyme in the red blood cell that accelerates the union of CO2 and water (pg. 291)
chloride shift increases the Cl content of erythrocytes in venous blood more than in arterial red blood cells
carbamino compounds form when carbon dioxide reacts with amino acids in blood proteins
Haldane effect interaction between oxygen loading and carbon dioxide release that facilitates carbon dioxide removal in lung (pg. 292)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
