Lung Tissue

sm_lung histologyLung histology

This illustration was created from a microscope slide of alveolar tissue from the lungs. The majority of the illustration is empty due to the volume of empty space found in the lungs for gas exchange. There are also blood vessels with red blood cells (white) to transport gases. The alveolar wall is only one cell thick, and appears almost as lines as opposed to areas in the illustration.
