Is it True??

Question

Is It True that your blood is blue on the inside...but when it hit's air it turns red?? I have a hard time thinking this true.

Answer 1

No, blood contains hemoglobin which turns it red. When you see it from the outside, though, inside your blood vessels, it looks blue. This is because the blood vessels we can see are all veins, blood vessels which transport blood back to the heart and lungs from the body - that blood has already released much of its oxygen to the body, which makes it a bit darker, so when we see it under the skin, it looks blue.

Answer 2

Google search: blood color

According to this page, blood is bright red when oxygenated and dark red when it is not. I'm not sure why surface veins appear to be green.

"So, what all these little bits of evidence say is that both the oxygen content of the blood AND the overlying skin affect the apparent color of the veins you see."

Answer 3

Yeah and you can see this is the case by the colour of your veins through the skin of your hand. Veins are blue and arteries are red (I think) due to the fact that one carries oxygenated blood and the other deoxygenated

Answer 4

It's a darker shade of red inside, when oxygenated it turns brighter red

Answer 5

Blood is a highly specialized circulating tissue consisting of several types of cells suspended in a fluid medium known as plasma. The cellular constituents are: red blood cells, which carry respiratory gases and give it its red color, white blood cells (leukocytes), which fight disease, and platelets, cell fragments which play an important part in the clotting of the blood. Medical terms related to blood often begin with hemo- or hemato- (BE: haemo- and haemato-) from the Greek word "haima" for "blood." Anatomically, blood is considered a connective tissue from both its origin in the bones and its function.

Functions of blood are:
supply of oxygen to tissues (bound to hemoglobin which is carried in red cells)
supply of nutrients such as glucose, amino acids and fatty acids (dissolved in the blood or bound to plasma proteins)
removal of waste such as carbon dioxide, urea and lactic acid
immunological functions, including circulation of white cells, and detection of foreign material by antibodies
coagulation, which is one part of the body's self-repair mechanism
messenger functions, including the transport of hormones and the signalling of tissue damage
regulation of body pH
regulation of core body temperature
hydraulic functions, including erection (see also jumping spider)

Problems with blood composition or circulation can lead to downstream tissue dysfunction. The term ischaemia refers to tissue which is inadequately perfused with blood.

The blood is circulated around the lungs and body by the pumping action of the heart. Additional return pressure may be generated by gravity and the actions of skeletal muscles. In mammals, blood is in equilibrium with lymph, which is continuously formed from blood (by capillary ultrafiltration) and returned to the blood (via the thoracic duct). The lymphatic circulation has been called the "second circulation".


Color

In humans and other hemoglobin-using creatures, oxygenated blood is bright red. This is due to oxygenated iron 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. However, due to an optical effect caused by the way in which light penetrates through the skin, veins typically appear blue in color. This has led to a common misconception that venous blood is blue before it is exposed to air. Another reason for this misconception is that medical charts always show venous blood as blue in order to distinguish it from arterial blood which is depicted as red on the same chart.
