Podocytes video animation. Podocytes are cells in the Bowman's capsule in the kidneys that wrap around surfaces of glomerular capillaries. Podocyte cells make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place. Bowman's capsule is a part of the nephron that forms a sack around the glomerulus. VFX company Polymime offer medical animations such as this podocytes video animation to download royalty free.
