Gas exchange

TermDefinition
respiratory membrane 1 layer (alveolus) + 1 layers (capillary)
Alveolus high oxygen from atmosphere
capillary low oxygen blood from heart arrives @ lungs; has high CO2 from heart arrives @ lungs
boyle's law the pressure of a given quantity of gas is inversely proportional to its volume
dalton's law total pressure of a mixture of gasses is equal to the sum of the pressure of individual gasses
henry's law ^ solubility ^ pressure
bronchioles Chnage in diameter; regulate ventilation, regulate air delivery to alveoli
bronchoconstrict decrease ventilation
bronchodilate increase ventilation
perfusion blood delivery to tissue (alveoli) -regulate blood in capillaries arterioles vasoconstrict= decrease perfusion vasodilate= increase perfusion
ventilation movement of air in & out regulated by bronchioles
exhale respiration gas exchange @ lungs/alveoli oxygen to blood CO2 to atmosphere
internal respiration gas exchange @ tissues oxygen to tissues CO2 to blood
cellular respiration cells use oxygen to make energy (ATP)
how does gas move down its pressure gradient

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.

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.
