Dog's small intestine is composed of two different parts: one that looks like muscle tissue and another part seems to be inside part of intestine.

Overall description.

Muscle Tissues

Like dog's esophagus has muscle tissues, dog's small intestine also has parts of muscle tissues as well. These muscle tissues look so similar.

Image	Data	Description
	200x	There are many cells among the muscle tissues. It is the same as the muscle tissues from dog's esophagus.
	400x	This part of muscle tissues looks different than other parts of muscle tissues. At the right side of the image, cells are gathered together more closely.

Intestine Part

The pictures are focused on the intestine part of dog's body. Many cells are located at the part of the intestine.

Image	Data	Description
	200x	Darker area seems to be the wall of the intestine, and the lighter area seems to be inside part of the intestine.
	400x	More cells are found only in the wall of the intestine. A few number of cells are located inside of the intestine.

Edge of Muscle Part

Muscle parts have two different shapes. Cells in the edge side of the muscle tissues are not long, and they are circular. On the other hand, cells in the middle part of muscle tissues are ellipse shaped.

Image	Data	Description
	200x	The cells in the right side of the muscle tissues are more circular than the cells in the left side.
	400x	Muscle tissues form a circular shape.
