A friend and I were having a discussion about what occupies "empty space" within a body or is there such a thing as "empty space". Is it air? A fluid? Is it a little bit of connective tissue? What?

Suppose the aorta springs a leak because of an aneuryism, I believe the blood ends up in the back and manifests itself as pain. Why?

I do remember disecting worms and frogs and I seem to remember empty space. But these were not freshly killed specimins.

Well to my understanding there is no empty space, and when you bleed into your body that causes the skin to darken and bruise on the outside, I think that is called a hematoma, but that may just be bleeding within the skin. Ask J_9. She would probably know.

Empty space eh?

Well, the simple answer to the question," what occupies empty space?", is nothing. Once space is filled, it's not empty any more.

So what happens if there is an empty space in our body? That depends on the area. If it's in the brain, then a fluid will fill it. I think the same idea goes for the rest of the body, like burns will produce puss, and water, and such, and yeah, that sound what you want. I could check my medical books but I'm short on time, sorry.

Hope that helps, peace.

Blood around the lungs would cause pain similar to pleurisy which also reduces the amount of air that can enter the lungs and the compression of the fluid or blood puts pressure on the nerves and spinal column. But if the aorta leaks from an aneurism, I don't think the pain will be felt for very long because death will come quickly. This is all based on logic and things I have read, not on any medical training. I could be wrong.

Firstly, if something like fluid or connective tissue were to occupy empty space, then we wouldn't have empty space.

Now, we don't have empty space in our bodies. All spaces are occupied by something. In our joints we have senovial fluid, etc...


Suppose the aorta springs a leak because of an aneuryism, I believe the blood ends up in the back and manifests itself as pain. Why?

Because the blood is not supposed to be there. You see, it causes an increased pressure in that area, whenever and wherever there is increased pressure there is pain.

burns will produce puss
"Puss" is a cat. You want the word "pus."

You've heard of the story "Puss in Boots"? Puss is a cat.

Pu$$y cat? Or if you can't pronounce certain letters -- puddy tat?

I could go on, but you've got it now.
