Test 2 Flashcards
Tuberculosis actually does what inside the macrophage and eventually kill it?
Reproduces
eukaryotic cells use oxygen to do what?
burn carbs, lipids, and protiens to make ATP
what is Fick’s Law?
Rate of Diffusion=moles of substance accross membrane per second
what is ficks law describing?
the gas exchange over short distances.
the first part of ficks law is what?
Large surface area increases gas exchange
What is the second part of ficks law?
The thinner a respirator surface makes more diffusion
what is the third part of ficks law
the larger the partial pressure gradient of the gas accross the surface the more diffusion
what is partial pressure?
the pressure of a particular gas in a mixture of gases
what is bulk flow?
gas exchange with a transport
bulk flow requires what mechanism to happen?
a pump
what is counter-current exchange?
the water current and the gills being oppositely oriented
what is a concurrent flow?
the gradient between two solutions large at the start and declines at the end and the body solution is not cooled to cold
what is a countercurrent exchange?
the slight gradient between leave both solutions respectively hot and cold
what is the constant gradient percentage in countercurrent exchange in fish gills?
10%
