Dog's cardiac muscle is like a piece of garment that is torn off. There are many empty spaces on the muscle piece. The muscle piece is comprised of countless tissues.

Main Part

Main part of the cardiac muscle is comprised of countless tissues. Inside of these tissues are cells. These cells have various shapes. The shapes of nucleus are circular, ellipse, and long.

Image	Data	Description
	100x	At 100x, tissues seem to have vertical patterns in the picture. These tissues are transparent; nucleus are found inside of the tissues.
	200x	The picture is zoomed on the surface of the main part. This area has the vertical pattern and little bit scaly texture.
	400x	The cells are found inside of the transparent tissues. The size of these cells varies, but they have similar colors.

Torn-off Spaces

There are many spaces that appear as white at 40x. When zoomed on these areas, some of the white spaces are filled with substances. These substances are transparent and look similar to fog.

Image	Data	Description
	200x	These transparent substances are visible in the white space. It seems to connect the gap between the disconnected areas.
	200x	There are many spaces empty. Only a few cells are located in these white spaces. In these spaces, the transparent substances are not found.

Circular Shape

The tissues form circular holes. These holes are found near the torn-off spaces. Inside of the some holes contain the transparent substances, but some holes contain nothing.

Image	Data	Description
	200x	There are two holes in the picture. One hole is circular, and another one is ellipse-shaped. The transparent substances that is often found in the torn-off spaces are found in these holes, too.
	400x	The tissues form the hole on the edge of the muscle piece. Nothing is found inside of the circular hole.
