Dog's smooth muscle piece is divided into three layers. The top layer composes most of the piece. The middle layer is transparently pink, and the bottom layer has many bubbles filled with cells.

Top Layer

Some area in the top layer is divided into several islands. Each island is comprised of many cells and, white bubble-like substances are found around the island. Some areas are not divided and have a vertical pattern.

Image	Data	Description
	100x	The image shows the several islands divided on the top layer. Some white bubble-like substances are visible.
	200x	This picture is focused on the area that are not divided into several islands. This part has a line pattern. The white bubble-like substances are also found in this area.
	400x	At 400x, each island has lighter outside edge with white bubbles. Many nuclei are visible at the middle of the island.

Middle Layer

Middle layer contains transparent tissues and another tissues that have horizontal pattern. This pattern is similar to the one in dog's skeletal muscle. There are transparently pink tissues and red tissues.

Image	Data	Description
	200x	The picture shows the transparent tissues that contain several cells. There are some areas with dark substances.
	400x	These red tissues form a ring speculated to be a cross-section of a blood vessel. Inside of the ring is red objects, which seems different from nuclei. It seems to be a drop of blood.
	200x	The tissues have horizontal pattern, which appears as stripes. All nuclei found inside of these tissues are long and ellipse shaped.

Bottom Layer

The bottom layer is comprised of countless bubbles filled with cells. This pink layer is little bit transparent.

Image	Data	Description
	200x	The picture is focused on the lighter area between the two different tissues. The entire shapes of some cells are visible.
	400x	The image shows the bubbles filled with cells. The white bubble-like substances seem to appear on this layer again.
