It just gets more confused.

The umbilical arteries/veins are like the pulmonary in that arteries are deoxygenated blood, veins are oxygenated.

Looking at the umbilical artery here:

http://en.wikipedia.org/wiki/Umbilical_artery

there are a few images, mostly from Gray's Anatomy.

One shows the arteries red (even though deoxygenated).

Another shows the vein red (and the arteries kind of purplish colorless).

Quite different from Grays drawings of the pulmonary arteries, which are clearly blue, with the veins red.

So I give up trying to make sense of it or seeing if there is a consensus.

I just think at this point, different people do it differently, and even the same person may or may not be consistent.

Well, it irritates me a little, but not too much.

In any case, thanks for playing my games, and for commenting on them. It gives me something to think about, anyway. And good commentary does help people improve their games.

I appreciate it very much.

Thanks again for responding.

I'm not sure if there really is a convention for red as oxygenated blue as deox. Nor am I sure that there is a convention for red as artery, blue as vein.

But I did find this page with several drawings from different sources:

http://en.wikipedia.org/wiki/Pulmonary_artery

All the images that have color show pulmonary arteries blue, the veins red.

Two images are old (Gray's anatomy), others more modern. One is from the US government.

So I can see how it could go either way. But in this case, I think I'll remain true to the original drawing. And that despite the fact that you spotted a genuine error in the same image, which I did correct. (Not to mention the alternative terminologies which I incorporated.)

In this one area of vein artery color, the situation may be more ambiguous, but I'm confident that if what I show isn't the "One Right Way", it is at least an acceptable alternative.

Thank you again for your comments. You helped me improve the game.

OK, so after looking at the other items:

Regarding the cricoid:

I think the drawing I used does indeed misuse the term for the Cricoid cartilage (or simply, cricoid). There should only be one of those, and it clearly points to two ligaments. Therefore, a more generalized term should be used, as you suggest.

Regarding the carina:

Essentially, the two terms "Carina of Trachea" and "Tracheal Bifurcation" are synonymous. If there is room in the text box, I will add "bifurcation" in parentheses.

Also, if the text box permits, I will add "branch of" to the pulmonary artery and veins as a clarification.

I may also put a note in the game comments regarding some of these items, the artery/vein thing especially. It confused me at first, and it is obviously counter-intuitive.

Thanks again for your comments. Although I try to be as accurate as possible in my games, errors are inevitable, either my mistakes or glitches in the original images. Unless I get feedback from people who play the games, and see glitches, I can't fix them.

And it's especially important to get feedback on older games. Those of who have created over 100 games really rely on this kind of input.

If you find errors in games here, please tell the authors. Anyone who is serious about their games will appreciate it. (There are others who will simply ignore you and a few people who react negatively, but these people are generally not producing very many games). Most game authors will appreciate your input, thank you for it and make changes if necessary (or at least explain why they think changes are not necessary).

Thanks for listing what you saw in the Respiratory system (advanced). First, regarding the pulmonary artery and vein:

It is true that usually red represents the arteries (oxygenated blood), and blue the veins (deoxygenated blood).

But in the pulmonary veins/arteries this is reversed: the heart feeds deoxygenated blood into the lungs via "blue" arteries and oxygenated blood arrives back at the heart via ) "red veins". To be honest, when I first saw this in the drawing I used, I also thought it was a mistake. It took some thought before I realized why it was done this way, seemingly against convention.

The other items I am still trying to track down, and I see I may have to make some changes or at least extensions of terms. I'll get back to you on that.

Thanks again,

Tickman

oh thank you for your statement! i admit that it should be stomach and not spleen...i have already changed it...sorry for the inconvenience...thank you again..

Then please let me know what they are, so I can look into it and make any necessary corrections.

Please do not publish games that you can suspect other people will take offence to.

You are welcome to continue creating games but please do think about this before publishing games again.

Thank you for respecting the rules of the site.
