RED BLOOD CELLS 7,000X - 3D IMAGES

Try either the small pair or the larger pair. It works easiest if you divide the two images by holding something (like a card) between them, helping your left eye to only focus on the left image, and your right eye to focus only only the right image. If you cannot get this to work, on the smaller images, try the larger images. If you cannot get either to work, then maybe print the pictures and try again on the printed images. Good luck.

This is a pair of photos of red blood cells from the kidney of a rat. They are magnified 7,000 times. Red blood cells in mammals like the rat, have a donut shape like these because they lose their nucleus. It is then concave in the middle as can be seen in the photos. Red blood cells are designed to be able to carry oxygen from the lungs to all of the tissues in the body.
