This question asks, which of the following is where most microbes filtered out of fluids that accumulate in the body tissues end up? so another way to say this is which of these is responsible for filtering lymph.
00:18
Okay.
00:19
So there's a couple ways to approach this question.
00:22
You could just go through and define all of them.
00:26
But i think at this point we're pretty familiar with this vocabulary, at least in terms of which parts of the body these are dealing with.
00:34
Remember, the paracardium is the sack around the heart.
00:38
This has nothing to do with lymphatic fluid, so this is not a good choice.
00:43
Similarly, blood capillaries are important for delivering the volume of fluid that will eventually become lymph, but they themselves are really focused on oxygen transport, nutrient transport, and other diffusion of molecules in and out of the tissue space from the blood.
01:03
So again, not the best choice.
01:06
Okay, so we've narrowed this down to the spleen and the lymph nodes...
