Schwarz-weiß-Abbildung
Transmission electron microscope image of a thin section cut through the pancreas(mammalian). This image shows a capillary within the pancreatic tissue(acinar cells in this image). Note the abundance of rough endoplasmic reticulum in the acinar cells. There is a red blood cell within the capillary. The capillary lining consists of long, thin endothelial cells, connected by tight junctions. The image shows fenestration of these endothelial cells. The image also shows synaptic vesicles in the neuron(nerve cell) next to the capillary.

Self made ophtalmogram of the retina of the right eye. It shows the optic disc as a bright area on the right (nasal side) where blood vessels converge. The spot to the left (temporal side) of the centre is the macula. The grey, more diffuse spot in the centre is a shadow artifact.
