Good to know
Blood consists of a mildly alkaline aqueous fluid (plasma) containing red cells (erythrocytes), white cells (leucocytes), and platelets; it is red when oxygenated and purple when deoxygenated. Red blood cells carry the protein haemoglobin, which gives blood its colour and can combine with oxygen, thus enabling the blood to carry oxygen from the lungs to the tissues. White blood cells protect the body against the invasion of foreign agents (e.g. bacteria). Platelets and other factors present in plasma are concerned in the clotting of blood, preventing haemorrhage.
