Few days ago, me and @nanosesame decided to try on a little project, Science Blind Draw. Our first test topic was Human Anatomy, and here is @nanosesame's post, please go check other post of @nanosesame for her other talented works~
Before I start to explain a little bit more about the drawings, I would like to get some terminologies clear.
- Tissues refers to cellular organisation of cells, usually with similar cell type group together.
- Organs refers to a collection of tissue to perform certain type of physiological function.
Most of the terms she used in the drawing refers to organs, yet for some case, for example the rectum, it is usually considered as part of the colon (large intestine), and along with the small intestine to make up the organ intestine.
This also applies to the cerebellum, which is the "small brain", which along with the cerebrum to make the majority of the organ "Brain"
The key confusion that @nanosesame made was the location of the small and large intestine, the large intestine is usually presented as outer region of the inner located small intestine. The small intestine is responsible for uptaking most of the nutrients we obtained from digestion of food. While the minerals and water are usually uptake in the large intestine. That's why you get dry poo if you don't drink enough water, the water in food are being absorbed dry in the colon.
The intestines along with the stomach, esophagus (eating duct) <-- this was missing in the drawing, all the way from the mouth to anus are your Gastro-intestine organ system. That is important for our food intake and digestion, and anything inside the Gastro intestine organ system is actually not part of you, they are just enclosed environmental that does not contains any cells from you. Within all our body's tissue, there are no bacteria or microbes, those microbes that "resides" on us are limited to the "surface" of our body, on our skins and in the Gastro-intestine organ system (it is outside of our human cells)
Pick the right side
Anyone spot out another confusion? There is actually "side" difference between our body, that is if our body is chopped in half vertically, we get different stuff on the two halves. Many of us know that the heart is left of us, but in real its majority portion is located in the middle, with part of it shifting more to the left. BUT hold on, you say its to your left, but why is the drawing on the right? For human anatomy drawings, we always draw them as if the body is opened facing us <-- historical reasons i guess, the science in the old time, i guess. Our livers are located on the right of us, but should be drawn on the left part of the image, while the stomach occupies the other half, you can try to feel your stomach next time you have a full meal.
Additional comments
Both the pancreas and the spleen are flat tongue like organs located in as the images on the side of her drawing. And I will not comment on the size of the kidney or the ovaries, but the kidneys are higher than you think, even if you pee at lowest part of your trunk.
At first I thought the blue thing that runs all over the body is the nervous system, but it turns out to be blood vessels XD, usually red are denoted as leaving the heart and blue are the vessels going back to the heart~
This is the first test of the project, hope everyone learnt something from this post XD.
