Blood cells. Coloured scanning electron micrograph (SEM) of a human red blood cell (erythrocyte, red) and a white blood cell (leucocyte, purple). These are the two main cell components of blood. Erythrocytes are carriers of oxygen and carbon dioxide. Their biconcave surface provides maximum surface area for the exchange of gases. The lymphocyte is involved in the immune system's defence mechanisms Stock Photo - Royalty-Freenull, Code: 679-02685066

B-cell, coloured scanning electron micrograph (SEM). B-cells are a type of white blood cell involved in immune respone. They account for 10 per cent of the body's lymphocytes. On encountering a foreign antigen, such as a bacterial surface protein, the immature B-cell either divides into a number of plasma cells, which produce antibodies, or it matures into a memory cell. Memory cells remain in the Stock Photo - Royalty-Freenull, Code: 679-02685103

Human blood cells, coloured scanning electron micrograph (SEM). Seen here are red blood cells (red), a lymphocyte (pink), a neutrophil (large cream cell), a macrophage (green) and platelets (small cream cells).

Blood cells, coloured scanning electron micrograph (SEM). Seen here are slightly crenated (wrinkled) red blood cells (erythrocytes) and a single white blood cell (blue). The main function of red blood cells is to distribute oxygen to body tissues, and to carry waste carbon dioxide back to the lungs. White blood cells are part of the immune system; they destroy and remove old or aberrant cells and Stock Photo - Royalty-Freenull, Code: 679-02685077

Light micrograph of human red blood cells (erythrocytes), with two unidentified white blood cells (leucocytes) near the centre. The function of the erythrocytes is the distribution & transport of oxygen & carbon dioxide to & from the cells of the body. Surrounded by a thin elastic membrane, the whole of the interior is filled with haemoglobin, an iron-containing red pigment which has a good oxygen Stock Photo - Royalty-Freenull, Code: 679-02683615

Herpes virus particles, coloured transmission electron micrograph (TEM). Each particle (virion) of this virus, the HHV-6 (human herpes virus-6), consists of a double stranded deoxyribonucleic acid (DNA) genome surrounded by an icosahedral capsid (yellow), which is itself surrounded by an envelope covered in glycoprotein spikes (blue). HHV-6 infects white blood cells, specifically T lymphocytes, (o Stock Photo - Royalty-Freenull, Code: 679-02682279

Myeloid white blood cells. Coloured scanning electron micrograph (SEM) of human myeloid white blood cells found in bone marrow. A type of leucocyte, these myeloid cells give rise to many types of white cells in the blood. They are undifferentiated, rounded in shape with typical protuberances on the cell surface. As a precursor cell in the bone marrow, they give rise to platelets, and white blood c Stock Photo - Royalty-Freenull, Code: 679-02683617
