Where can I find the elasticity of the stomach?

Question

Where can I find other mechanical properties of internal organs?

Answer 1

Elasticity of stomach comes from the circular and longitudinal smooth muscle layers as well as the many surrounding connective tissue layers.
See a good human histology atlas like di Fiori's for the multiple tissues and layers of various organs and how each of the many tissue layers contribute to the varying degrees of elasticity. Each tissue type gives a UNIQUE mechnical property. There are four main tissue types (epithelial, muscle, nervous and connective)but over 200 different kinds of these 4 types in human organs and systems. Each is designed magnificently to offer very specific mechanical properties to these various organs.

Answer 2

Well, the stomach usually holds about a quart. Unless it's all stretched out and huge. Or if you get a gastric bypass and it's tiny. I guess plastic surgery sites might tell you about that.

Most other organs don't store liquids (now, the gall bladder does, and the kidneys and spleen and liver might hold a little liquid while they're working on filtering the blood.) But the heart pumps (doesn't store blood), the lungs breathe (blood flows through the little alveoli, but it doesn't stay in them), and the intestines hold solids and liquids but keep them moving as long as everything is working properly.

Good question. You might have to go to a gastroenterology site for the gut stuff, and maybe a site on drugs to see healthy vs. damaged livers. I don't know exactly where to look, but maybe check Discovery Health or someplace like that--they have lots of gross medical footage, so maybe they have some on their site.
