I have to write a persuasive essay on the most important organ of the body...

Heart, Skin or Liver?

My teacher told me there was a right and wrong answer which didnt make sense to me because you would die without any one of them. She told me the answer would become obvious once I started researching but it is not obvious.

Help.

i'm guessing heart...
i don't know, i'm not a biologist...

though it could be skin...
argh...
i don't know...

sorry..
:P

I'd say skin. Heart and Liver could be substituted with machines.


....... Maybe

Skin - Protective, insulating, provides a means of excretion.

Liver - Processes toxins, cleanses what you eat.

Heart - Your cells need oxygen. The heart pumps blood to every inch of your body. If your heart stops, you stop.

Guess which one you CANNOT live without...

Of a human body or just in general?

Because all complex organisms have a "skin" but not all of them require hearts and/or liver.

All 3 are essential to a human body. It's a bit of a retarded question.

I think he is talking about humans. We can go on without skins and some beneficiary adaptations might make the liver less important, but our heart is key.

Have you seen the asian ass pron thread? they have a thread dedicated to math and science, but it probably wont get answered. just putting that out there.

You'd need a f*ckload of those beneficiary adaptations to make the liver less important. However, it's integral to so many processes I doubt it will be rendered unimportant. It has many more functions than people generally know of. You will die without a liver, which is a fact. You'd also die without the adrenal cortex.

Its about humans... and now I realize that the paper says "tell which organ is most important based on which one has the most functions for homeostasis.

Without the heart, the other organs can't keep fulfilling their original functions. Eventually the lack of liver would kill you, but until then your heart and skin would keep functioning.

edit:

Specifically, wouldn't our skin give us the most advantage over other mammals thus making it the most important for us? Sweating FTW, suck it chimps.

Im pretty sure the answer is liver.

Without skin we'd be open season for all the bacteria and viruses going though. And nowhere to store fat. No sweat glands, not that we'd need them cus we'd be freakin freezing all the time. And we'd all be ugly.

The liver produces tons of enzymes we need for energy metabolism and homeostasis.

The heart pumps oxygenated blood.

They're all essential.

Obvious answer is heart if we're talking human/animal.

I was referring to it in the sense how our digestive appendix has evolved to be of no use to us. Most parts in the human body are very specialized for their tasks and we can't operate without them.

The paper says based on HOW MANY functions. The heart has one major one. The skin has like 3 obvious ones. The liver has over 500.

Well, the liver controls a lot of metabolic homeostasis. In fact, the liver has most metabolic functions associated with it than any other organ in the body. However, the heart is the biggie in cardiovascular homeostasis, and without cardiovascular homeostasis, none of the other forms of homeostasis can be controlled, as homeostasis is heavily governed by feedback systems found in the hypothalamus, to name one region, and the transport of hormones.

In a direct analogy to computers, you can have an awesome collection of peripherals attached to your motherboard, but without a processor, nothing runs. It's the same way with humans. What good is just a brain? You need the peripherals too.

If your question is asking for one specific organ, you should write "This question is retared." and turn it in.

Then the paper is irrelevant and a waste of your time. Importance cannot be determined by quantity. Importance of something of this nature should only be based on the effect on the body.

In a human body, you need the heart and lungs to motivate cellular respiration. But as a human, you are nothing without your brain monitoring your body and triggering all of the feedback mechanisms that keep the rest of the body under homeostasis.

If I had to pick an order of importance, it would be (1) Heart/Lungs (2) Brain (3) Rest

I think we can all agree that the flaw in all of this is the title of the paper. The teacher is asking for a quantitative analysis and asking which organ is more important, which is frankly a stupid thing to do. Obviously all three are essential to human life and homeostasis in normal conditions, however, giving that answer doesn't answer the question set, because then it's a qualititative analysis.

TS, slap your teacher and tell her the Pit shall be taking over her classes for the rest of the semester.

Without Skin all your muscles will be completely exposed (not the good kind of muscle)

Without your heart you can't get blood through your body so yeah

As for the Liver:

Can we include glycolysis, pyruvate oxidation and oxidative phosphorylation onto the Kreb's Cycle memorising task, including all the intermediates? If I had to do it, I'm gonna make damn well sure everyone else I end up teaching has to do the same.

as a whole, the Pit is actually pretty freaking smart! I've learned tons of things here.

sadly, I've been drunk 90% of the time so i can't remember anything, but I KNOW I learned SOMETHING.

EDIT 2: Im a sophomore in high school... btw.

Been there, done that. Was the reason I chose Aerospace Engineering over Biomedicine. Turbojet cycles are more fun than the CA Cycle anyway, plus, if you drop that "turbojet" in conversation, you'll have more women crawling over you than the IDF over Gaza. Whereas with "Krebs" people simply assume you were being indiscreet about your itchy pubes.
