Amazing Body Shots

Almost all of the following images were captured using a scanning electron microscope. Incredible detail of 1 to 5 nm (nanometer) in size can be detected...

Red Blood Cells: They look like little cinnamon candies here, but they're actually the most common type of blood cell in the human body - red blood cells (RBCs)

Blood Clot: Well, here's what it looks like when red blood cells get caught up in the sticky web of a blood clot. The cell in the middle is a white blood cell.

Alveoli in the Lung: This is what a colour-enhanced image of the inner surface of your lung looks like. The hollow cavities are alveoli; this is where gas exchange occurs with the blood.

Lung Cancer Cells: This image of warped lung cancer cells is in stark contrast to the healthy lung in the previous picture

Villi of Small Intestine: Villi in the small intestine increase the surface area of the gut, which helps in the absorption of food. Look closely and you will see some food stuck in one of the crevices.

Human Egg with Coronal Cells: This image is of a purple, colour-enhanced human egg sitting on a pin. The egg is coated with the zona pellicuda, a glycoprotein that protects the egg but also helps to trap and bind sperm. Two coronal cells are attached to the zona pellicuda.

Human Embryo and Sperm: It looks like the world at war, but it is actually five days after the fertilisation of an egg, with some remaining sperm cells still sticking around. This fluorescent image was captured using a confocal microscope. The embryo and sperm cell nuclei are stained purple while sperm tails are green. The blue areas are gap junctions, which form connections between the cells
