Question

Is it possible if I ask some questions of science here in prep for a test tomorrow? I really need help. Medals will be given out.

Answer 1

What kind of science?

Answer 2

Like Body Works (7th grade)

Answer 3

Yeah, hit me. I think I know that stuff well. Could you help me with a geometry question afterwards?

Answer 4

I'll try because I have math test tomorrow as well.

Answer 5

Okay. First question, "The shape of an organ is determined by what it does, give one example."

Answer 6

I'm thinking, give me a second.

Answer 7

Okay

Answer 8

Maybe the stomach? Designed to have something go into it through the top, and then it goes down into the intestines.

Answer 9

Well I wrote that the small intestines' surface area is pretty large so it enables a faster speed for nutrient absorption.

Answer 10

Explain how the heart acts as an organ and a muscle.

Answer 11

That's a tough one.

Answer 12

Let's brainstorm for the answer.

Answer 13

An organ is something that performs a vital function in the body, and is comprised of many tissues, correct?

Answer 14

Yes

Answer 15

And it is a muscle, in the fact that it is expanding and contracting, perhaps?

Answer 16

So I wrote for that: deliver nutrients to the body and returning waste for removal

Answer 17

And yes muscles contract and expand due to the need for oxygen

Answer 18

Would that be a sufficient answer, then?

Answer 19

The heart performs a vital bodily function necessary for life, and expands and contracts like a muscle would.

Answer 20

Yeah thanks

Answer 21

Anything else?

Answer 22

Yes

Answer 23

Go for it.

Answer 24

After nutrients are absorbed through the small intestines, they are needed by every single cell, so how are they transported to through the body?

Answer 25

Well, how do nutrients typically get delivered to cells?

Answer 26

That one, I am not too sure, but I know that the circulatory system transports nutrients throughout the body.

Answer 27

Don't quote me on this. But I think that the intestines have capillaries with cells going through, and on the walls are nutrients that were absorbed.

Answer 28

On the outside, of course.

Answer 29

Okay wait one moment.

Answer 30

I just read something .

Answer 31

http://biology.stackexchange.com/questions/16389/how-do-nutrients-get-to-the-cells-they-need-to-get-to

Answer 32

It looks like it gets transported to the liver, where it is then transported to cells that pass through the liver seeking nutrients.

Answer 33

Thank you. I have to go now. Dinner time.

Answer 34

Alright, good luck on your tests!

Answer 35

Thanks :)
