heart

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 human body.

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 63 typed relationships for it, across 11 kinds of connection. part of anatomical system, heart plus pericardium and thoracic segment of trunk, and 1 more.

Supply and innervation

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

Also called

Questions

Where is the heart?

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

What does the heart connect to?

Part of: anatomical system, heart plus pericardium, thoracic segment of trunk and cardiovascular system.

Is the heart the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
