pulmonary artery
Let an agent explain the pulmonary arteries and their branching, relay anatomy and physiology from anatomical sources, describe conditions in general terms, identify emergencies, and route personal questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the pulmonary arteries and their branching, relay anatomy and physiology from anatomical sources, describe conditions in general terms, identify emergencies, and route personal questions to clinicians.
The artery that carries deoxygenated blood from the right ventricle of the heart to the lungs, beginning as the pulmonary trunk and dividing into the right and left pulmonary arteries, which branch within the lungs into lobar, segmental, subsegmental and smaller intrapulmonary arteries down to the capillaries around the alveoli; the pulmonary arteries carry low-pressure blood and are affected by pulmonary embolism, pulmonary hypertension and congenital anomalies.
What it is for: Carrying blood from the heart to the lungs.
It can be explain anatomy and branching; relay physiology; describe conditions; route emergencies and personal questions.
Distinguishing features
Deoxygenated blood in an artery
Low pressure
Branching with bronchi
Embolism site
What it looks like
Large vessels from the heart dividing into branches through the lungs.
Physical character
pulmonary trunk diameter: about 3 cm - adult
normal mean pulmonary artery pressure: about 14 mmHg - at rest
carries: deoxygenated blood note - unlike most arteries
How it is recognised
Artery from right ventricle to lungs
Pulmonary trunk, right and left pulmonary arteries, lobar, segmental, subsegmental and intrapulmonary branches
Pulmonary veins return oxygenated blood; bronchial arteries supply lung tissue from the aorta

- How should anatomical references be linked?
- The registry entry has merged aliases naming branch levels; should they be split off?
