A HISTOLOGiCAL SLIDE AS SEEN UNDER A LIGHT MICROSCOPE
You can watch a large pink area, but only few details can be distinguished at this magnification. In sections of other organs observed at the same magnification, it could be possible to distinguish some of their components, such as layers that make up the organ, large blood vessels, nerves. The three or four large empty spaces are probably blood vessels.
There are many small clear spaces in the image. Most of them are empty cavities of very small blood vessels, also called the lumen of the blood vessels (see the meaning of “Lumen” in the GLOSSARY at the main MENU.

Liver. Staining: hematoxylin and eosin. Very low magnification.
