-	The function of red blood cells is to transport oxygen around the body, to all the cells that need it. To do this, inside red blood cells is a red pigment: haemoglobin. As the blood passes past the [[alvoli]], the oxygen diffuses into the haemoglobin - forming oxyhaemoglobin. The amount of oxygen passign through into the red blood cells is maximised by the large surface area of the red blood cell. When blood passes capillaries near to cells which need oxygen, the oxyhaemoglobin becomes haemoglobin again. The oxygen has diffused out of the red blood cells into the tissue cells. While haemoglobin has oxygen in it, it is red; but without it is blueish purple. The [[blood]] therefore takes on this colour as it flows round the body. Therefore blood in the pulmanary vein and aorta is red, while blood in the vena cava or pulmonary artery is bluish-purple.	+	The function of red blood cells is to transport oxygen around the body, to all the cells that need it.

When blood passes capillaries near to cells which need oxygen, the oxyhaemoglobin becomes haemoglobin again. The oxygen has diffused out of the red blood cells into the tissue cells. While haemoglobin has oxygen in it, it is red; but without it, it possesses a colour which is dark red. The [[blood]] therefore takes on this colour as it flows round the body. Therefore oxygenated blood in the pulmonary vein and aorta is red, whilst deoxygenated blood in the vena cava or pulmonary artery is dark red: Venous blood, which leaves organs and returns back to the heart via these two channels, seems blue to the eye due to to a phenomena of light: this is known as 'Rayleigh scattering.' It is actually dark red in colour, only seeming bluish through veins due to the Rayleigh effect.

	'''Alloys''' are a mixture of two or more [[metal]]s (sometimes there are also [[non-metals]], such as carbon). The main plan with alloys is that they would be better at something than a normal metal on its own. For example, nickel and chromium are often added to steel to stop it rusting.
