What is considered the fuel filter of the body? Spleen, kidneys, or liver
 
Huh. It's right there on page 337 of Guyton.

What is the function of a filter?

What is the function of the spleen?

What is the function of the liver?

What is the function of the kidney?

What is the function of homework assignments?

See where I am going with this?
 
Please tell me this fuel filter analogy is from grade 11 biology or something, not out of a program training you for this profession ...

You do know this is an EMS forum right? There was a time when all of us didn't know what blood does and didn't know the difference between a pancreas and gall bladder.

Besides, as far as metaphors go, "fuel filter" is not too bad for one of these organs...as long as you remember that every single one of these organs does more than filter the bodies fuel ;)

Absolutely, but actually having a homework/quiz/whatever question asking, "which organ is the fuel filter," strikes me as childish and unprofessional.
 
It isn't a dumb question.. That is a question that was on my homework and I couldn't find it until eventually going with the liver which turned out to be correct. Not my fault that the people making the test decided to word it that way.
 
Well, it is a poorly worded question, but the big take away is, we won't do your homework for you. If you ask a question about a topic that you're having trouble with, we'll usually be able to point you in the right direction to help you figure it out on your own. (Because, learning...)

But, simply posting a question from your homework and expecting an answer ain't ever gonna happen.

Just because it was a real homework question doesn't mean it isn't a dumb question. Also, from a pure mechanical perspective, the kidneys (bowman's capsule) and spleen (lymph being pushed through and filtered for antigens) is much closer to a fuel filter than the liver.
 
That's why I posted it, because each one of them filter and I couldn't determine which one it was based on the wording "fuel filter". I agree it is a dumb question on there part.

No one said anything was your fault. But don't come here looking for us to do your homework for you. Historically we are very leery of that. If you want to discuss something or have a legit question we can be very helpful, but we can tell when you are just looking for the right answer.

It is a dumb question because each of those organs acts as "filter". The spleen is major component of the lymphatic system, "filtering" out various crud from not only lymphatics but old blood products as well. Probably the closest to a pure "filter" (if I was forced to choose). The kidney are, probably, on a day-today-basis, the most important "filter" in your body. Initially filtering out all kinds of crap and then selectively reabsorbing anything that maybe shouldn't be expelled from the body. Of the 3 I would say the liver fits the analogy the worst. The function of the liver is more about protein synthesis and metabolism of various biochemicals. Maybe it "filters" nutrient-soaked blood coming from the GI system, but it all it does is change things from one form to another and then releases it back into the blood stream. In that sense its more of a chemical factory than a fuel filter.

Also, remember that each of these organs have other functions as well.
 
The fact you have had a physicians assistant answering this question is cringeworthy, it is like trying to hammer a nail into a piece of wood using artillery fire.

In future don't use internet forums to answer homework questions and save you actually learning WHY the answer is what it is- and that applies to any career field unless you know the person's credentials and experience personally that posts.

If you TRULY want to expand your knowledge then youtube 'renin angiotensin aldosterone system' and the likes.
