What is the color of your blood inside your system (before it hits the air)?

Answer 1

Vertebrate blood is red. Always. It can be varying shades of red depending on its percent oxygenation, but it is never blue.

Minus the water, mammalian blood is composed of 97% hemoglobin. Hemoglobin is an iron-rich protein that is naturally red. The iron does need oxygen to be red, but it DOES NOT need to "hit the air" to get that oxygen. It gets it from its own chemical content.

Certain invertebrates do have blue blood, but that is because they don't have hemoglobin, but rather a copper-rich protein called hemocyanin.

Answer 2

You have 2 different blood vessels inside your body that circulate the blood. #1 is the arteries,the vessels that have a "pulse"( check inside your wrist below your thumb) these vessels carry oxygenated blood throughout your body,under pressure,that's what is called the "blood pressure".That blood is bright "cardinal" red,from the oxygen percent. #2 are the veins,they carry blood back to the heart and lungs so the blood can exchange carbon dioxide for oxygen,we breath this by- product out of our body when we exhale the air in our lungs.These vessels carry the darker blood is a dark "reddish purple" color,because the oxygen depletion,the "veins" also do not "pulse" because its not under allot of pressure etc. You don't have "blue" blood,that's a very old term that was used to describe sick babies with heart defects etc. Take care.

Answer 3

Have you ever donated blood. That's a vacuum tube/bag w/ no atmospheric air/oxygen changing it. It's still the same color depending on whether the blood is oxygenated or not. Oxygenated blood will be very bright red, where as deoxygenated blood is very dark red/purple (shown as blue/purple in books for illustration purposes only).

Answer 4

The color of your blood before it exits the aorta of your heart is a very dark red it almost has like a blackish look to it, which is what makes people think its blue. After it gets oxygen in it from your lungs it turns a very bright red almost kind of pink. Also if you get a very deep cut compared to a skin cut your bloods color is different.

Answer 5

dark red, unless you are royal like the others around here? lol

In humans and other hemoglobin-using creatures, oxygenated blood is bright red. This is due to oxygenated iron-containing hemoglobin found in the red blood cells. Deoxygenated blood is a darker shade of red, which can be seen during blood donation and when venous blood samples are taken.

The blood of most molluscs, and some arthropods such as horseshoe crabs, is blue. This is a result of its high content of copper-based hemocyanin instead of the iron-based hemoglobin found, for example, in mammals. While mammalian blood is never blue, there is a rare condition (sulfhemoglobinemia) that results in green blood. Skinks in the genus Prasinohaema have green blood due to a buildup of the waste product biliverdin.

Answer 6

Blood in the veins is a dark maroon.
Have you ever had blood drawn? The color is what you see in the tube when they take it out.

Blood in the arteries is bright red.

Veins look blue because of the overlying skin and tissue. The blood isn't blue.

Answer 7

This was talked about between me & some friends when I was YOUNGER !! & The conversation went something like this: The blood before any oxygen gets to it: Is either a bluish or green in color !?! Or possibly grayish in color !?! But ofcouse once oxygen hits it or expossed to OXY the color is much different than expected !?! `'R"r.r`r,r'.-

Answer 8

the color of your blood inside of u is blue when it hits the air it is red as u know.

Answer 9

Blue

Answer 10

Blood lacking in oxygen is rather a dark bluish red.
