heart in dogs

A myogenic muscular circulatory organ found in the vertebrate cardiovascular system composed of chambers of cardiac muscle. It is the primary circulatory organ. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the heart is

A myogenic muscular circulatory organ found in the vertebrate cardiovascular system composed of chambers of cardiac muscle. It is the primary circulatory organ. The atlas records it as a organ at the organ scale in the dog.

Where the heart is

It sits in the thorax and trunk, within the cardiovascular system. Positioned deliberately as part of this species body plan.

What the heart connects to

The atlas records 62 typed relationships for it, across 11 kinds of connection. part of circulatory system, heart plus pericardium and cardiovascular system.

Supply and innervation

Arterial supply: left coronary artery, right coronary artery and coronary artery. Innervation: cardiac nerve plexus and vagus nerve.

Also called
