Composition of the Blood Composition of the Blood. When a sample of blood is spun in a centrifuge, the cells and cell fragments are separated from the liquid intercellular matrix. Because the formed elements are heavier than the liquid matrix, they are packed in the bottom of the tube by the centrifugal force.The light yellow colored liquid on the top is the plasma, which accounts for about 55 percent of the blood volume and red blood cells is called the hematocrit ,or packed cell volume (PCV).The white blood cells and platelets form a thin white layer, called the buffy coat, between plasma and red blood cells.he light yellow colored liquid on the top is the plasma, which accounts for about 55 percent of the blood volume and red blood cells is called the hematocrit ,or packed cell volume (PCV).

Deoxygenated blood is a darker shade of red; this is present in veins, and can be seen during blood donation and when venous blood samples are taken.

Is deoxygenated blood blue? Venous (deoxygenated) blood is dark red. From The Franklin Institute : Because it lacks oxygen, the waste-rich blood that flows through the veins has a deep red color, almost like maroon. Because the walls of the veins are rather thin, the waste-rich blood is visible through the skin on some parts of the body.

Is blood ever blue and why does it appear blue in veins near the skin? Agreed - arterial (oxygenated) blood is bright red and and venous is much darker but still unequivocally red! Even in a vacuum it would still be red because of the red haem pigment, as Neil says. This I understand, but what then causes the optical illusion that makes it *appear* to be blue through the skin.

The Chemistry of The Colours of Blood However, red is not the only blood colour available – it also comes in blue, green, violet, and even colourless varieties – and this is a result of the specific chemicals that make up blood in different organisms. So, let’s start with what we already know. Most people will have learnt that human blood, as well as that of most other vertebrates, is red as a result of haemoglobin, a large protein found in red blood cells which contains iron atoms within its structure.

- The reason it appears bright red is that the combination of iron, oxygen, and hemoglobin absorbs higher energy wavelength light (blue and green) which leaves the red wavelengths available for our eyes to sense. The venous blood is never blue, it is a darker color of red than arterial blood, not blue.

Arteries carry highly oxgenated blood to the body and veins carry deoxygenated blood back to the lungs. The colour of your blood may be purely related to the location of the vein from which the sample was taken.

What color is deoxygenated blood? If you get blood taken, it's from a vein, and it's not blue. It never meets oxygen during the transfer. Deoxygenated blood is most certainly NOT blue, but a darker red. Veins are made blue by distortion of light by your skin which prefers to take in the red light spectrum and turn away blue.

- Clearly it does, since arterial blood is normally bright red, and venous blood is normally deep maroon. This fact is irrelevant in regards to the “blue veins” we see in skin. However, skin is also full of much smaller and more superficial microvessels.
