In fact, blood is made up of four components: red blood cells, white blood cells, platelets and plasma.

Why is your blood actually yellow?

The reason plasma is typically yellow in colour and not red like our blood is due to a pigment called bilirubin. Bilirubin is the end product of red blood cell (haemoglobin) breakdown. It is circulated in your blood then travels to your liver where it is processed and eventually removed.

What's the rarest blood type?

AB negative is the rarest of the eight main blood types - just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don't struggle to find donors with AB negative blood. However, some blood types are both rare and in demand.

Why is my blood green?

Hemoglobin contains an atom of iron to bind to oxygen. In sulfhemoglobin, the sulphur atom prevents the iron from binding to oxygen, and since it's the oxygen-iron bonds that make our blood appear red, with sulfhemoglobin blood appears dark blue, green or black.

Is blood yellow or red?

If we're talking proportions, the majority of your blood—55 per cent to be exact—is actually kind of yellow.

Is blood always red?

Blood is always red, but the shade of red depends on how much oxygen is in the red blood cells. When you breathe in, you are filling your blood cell with oxygen, and it gives them a very bright red color. As blood travels through your body, it loses the oxygen and takes on carbon dioxide (which you exhale).

Is your blood black?

Blood in the human body is red regardless of how oxygen-rich it is, but the shade of red may vary. The level or amount of oxygen in the blood determines the hue of red. As blood leaves the heart and is oxygen-rich, it is bright red.

Is human blood purple?

Human blood is red because hemoglobin, which is carried in the blood and functions to transport oxygen, is iron-rich and red in color. Octopuses and horseshoe crabs have blue blood. This is because the protein transporting oxygen in their blood, hemocyanin, is actually blue.
