Comments on a blood cell modeling attempt.

[i an not a nerd]

Hey all,

I was bored, so I decided to try and make a 3d blood cell. I thought that i'd post the early image here for people to check out and comment on (preferably constructful comments).

Tell me what you think of it!

P.S. I have no idea what a real blood cell looks like :p

Looks good. This is what a red blood cell (RBC) basically looks like.. Maybe a little flatter in the middle..
One question.... If you've never seen a RBC before how in the world did you come up with this?? :confused: :cool:

Well, i've only seen what they look like in cartoons lol. I wasn't sure if that was what they really looked like, but that was all I had to go on.

Pretty damn good as a first attempt, if I do say so myself. But considering we have about the same knowledge, that's not saying too much :rolleyes:

Okey, here is an updated version!

Very cool!!! This type of blood cell is known as an erythrocytes or Red Blood Cell. It's main purpose is to carry oxygen to the tissues, and to a less extent, remove CO2..

What made you decide to do this?

What made you decide to do this?

Well.... to tell you the truth, my sisters were watching the "Magic School Bus" and I saw a blood cell on it while going to my room (my room is in the basement by the tv room). Being bored, I decided to make a better looking version. :p

Of course, it being a cartoon version that I referenced from, I had to guess at the texturing/bumping. I assumed it was red, but not perfectly smooth. So i added a bump map to give it a bit of roughness (although I think they look kinda corroded...).

Hopefully I'll learn more in Biology next year.

and to a less extent, remove CO2
CO2 is so soluble in plasma that it doesnt need to be carried in cells as oxygen is by being bound to haemoglobin. Carbon monoxide however does bind to haemoglobin and is why it is a poisonous gas because it binds even more strongly than oxygen to the haemoglobin molecules. CO poisoning causes death by hypoxia but the individual remains pink and doesnt turn blue.

Yes it does... Something like 200 times more readily the O2 does.. It can be very serious... That's why it's important that everyone, who has a gas appliance, should have a CO detector in their homes.

Yes they can stay pink and they can show a good O2 sat, via pulse oximetry, despite the fact that their cells are dying due to a lack of O2 :(

Thank the good Lord that, where I work, we have several smaller hyperbaric chambers and one very large one. (http://media.integrisok.com/integris_hyperbaric.ram) (Real Media 1min.)

Pink or Blue.

Well "blueness" is not a direct function of hypoxia. Perceptible blueness is seen when there is a total of about 5g% of reduced haemoglobin circulating. So polycythaemics are blue much of the time and the very anaemic never go blue!!

[gracious]

Wow, that is very kewl! What imaging software do you use?

You know Jason1971, while reading your posts, it reminded me of speaking to my step-son who is an EMT in New Orleans...tee hee for a minute there I thought maybe it was him posting. :D

I'm using LightWave v8. No postpreduction work at all. (I can't afford Photoshop).
