Small intestine. Colored scanning electron micrograph (SEM) of a freeze-fractured of the small intestine. The surface consists of deep folds, called villi. The intestinal surface( pink) is exposed to food. The underlying structure of this surface is seen in the sectioned area. Surface (epithelial) cells (blue) are supported by connective tissue (red) that forms the core of each fold (villus). This central core of connective tissue is known as the lamina propria. This contains large blood vessels, capillaries, some smooth muscle cells and a blind- ended lymph vessel known as a lacteal. The folds increase the area for the absorption of nutrients from food. The height of a villus varies in a small intestine from 0.3 to 0.8 millimetres. Magnification: x800 when printed at 10 centimeters wide.Small intestine.

Illustration of Treponema pallidum bacteria, which causees syphilis. Syphilis is usually sexually transmitted, but may also pass from an infected pregnant woman to her unborn child (congenital syphilis). The last of three stages of syphilis is the most severe and can cause damage to the heart, blood vessels, brain and spinal cord. Treatment with penicillin drugs is effective if administered during the early stages.Illustration of Treponema pallidum bacteria, which causees syphilis.
