Description
Human red blood cells in physiological isotonic saline solution (0.9% NaCl), coloured scanning electron micrograph (SEM). Human red blood cells (RBCs), or erythrocytes, take up oxygen in the lungs and release it into tissues while squeezing through the body's capillaries. The cytoplasm of RBCs is rich in haemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells. The cell membrane is composed of proteins and lipids and this structure provides properties essential for physiological cell function (deformability and stability) while traversing the circulatory system, especially the capillary network. In humans, mature RBCs are flexible and oval biconcave disks. RBCs are the most abundant type of cell in human blood, accounting for 40% of the blood volume. Magnification: x1,000 when shortest axis printed at 25 millimetres.

Hi Dennis, Years ago you allowed me to use one of your images on my website. I don't know how I was lucky enough to get to know you a bit, in order to email back and forth. Now I would like to use an image and license it, but when I go to Science Photo LIbrary and try and search your name, it asks me if I mean Tennis Kunkel... I wrote you an email about it, but your old email address doesn't work. The image I want to us is one that was in an NIH show, according to what I can find on Twitter. Your work is SO amazing.
