Human tongue surface, coloured scanning electron micrograph (SEM). The tongue is covered in many backward facing projections called filiform papillae, which sense pressure. The papillae have a scaly appearance because they are constantly shedding their top layer of skin.Request/Download high-res file  Uncompressed file size: 51.4MB  Downloadable file size: 1.7MB

the microscopic blood vessels that carry nutrients to neurons in the brain, SEM. This sample, from Human cerebral cortex, shows a large blood vessel at the surface of the brain (top), which sends down thin, densely branched capillaries to deliver blood throughout the entire cortex.

Capillaries in lung. Capillaries surround the individual alveoli ,air sacs, allowing for the exchange of oxygen and carbon dioxide between the capillaries and the alveoli. Mammal **On Page Credit Required** - SEM X415  3.5" X 6.5"
