what is the colour of the blood?

Answer 1

Oxygenated blood is bright red in color while deoxygenated blood is bluish in color.

Answer 2

The color of blood comes from the red blood cells (RBC's, also called erythrocytes), which make up about 40% of blood, by volume. Each red blood cell is filled with hemoglobin, the protein which carries oxygen to tissues and carbon dioxide away from tissues. Hemoglobin carries oxygen by using heme, a large ring-like molecule which has at its center a single atom of iron, which is what actually binds to the oxygen.

The nature of heme that gives it these abilities is in the many double covalent bonds that form the ring. These double bonds can be shifted into many different configurations...

When oxygen binds to the iron atom in heme, the iron changes its shape slightly, which alters the resonance of the heme molecule. This new resonance gives off a different frequency of light, so the perceived color of the heme goes from dark red to bright red. When the oxygen is released into the tissues, the iron goes back to its original shape, and the heme returns to its normal resonance, so the color goes back from scarlet to maroon..

Answer 3

If you want to say Human Blood then,

RED.
The cellular constituents of blood are: red blood cells, which carry respiratory gases and give it its RED color because they contain hemoglobin (an iron containing protein that binds oxygen in the lungs and transports it to tissues in the body)

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.

Answer 4

Colour of the blood is red ,because of it contains the iron present in the haemoglobin of the RBC.

Answer 5

The color of blood depends on how much oxygen is in it. Oxygen-poor blood, most often found in the veins, is a dark red, sometimes bordering on bluish-purple. Well-oxygenated blood is a bright cherry red.

Answer 6

It is pale yellow in colour but when it is coming in contact with oxygen than turn in to red.

Answer 7

It is red because there are 4 things in your blood :platelets, white blood cells, red blood cells and plasma. Why is our blood red then and not white? Because our body contains riple the amount of red blood cells than white blood cells. This is where we get our color from. Good question!

Answer 8

IN HUMANS,THE COLOUR OF THE OXYGENATED BLOOD IS BRIGHT RED AND OF deoxygenated blood is dark red it is not blue.blue is only used to represent it in books etc

Answer 9

Red

Answer 10

In Humans, blood is red because of a presence of haemoglobin.Cockroaches have white blood because of absence of haemoglobin.

Answer 11

Human blood is red, insect blood is green
