Peyer's patch in dogs

The protruding lymphoid tissue located on the mucosa of the intestine that is composed of densely packed B cell follicles. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the Peyer's patch is

The protruding lymphoid tissue located on the mucosa of the intestine that is composed of densely packed B cell follicles. The atlas records it as a lymphatic at the organ scale in the dog.

Where the Peyer's patch is

It sits within the digestive and lymphatic & immune systems. Only the system is known. The position shown carries almost no spatial information.

What the Peyer's patch connects to

The atlas records 11 typed relationships for it, across 5 kinds of connection. part of intestinal mucosa and lamina propria.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the Peyer's patch. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.
