circulatory system
Let an agent explain circulatory systems, relay anatomy, physiology and comparative forms from physiology and medical sources, route cardiovascular emergencies to emergency services, describe the named forms including horse, bird and fetal circulation, and distinguish the circulatory system from the lymphatic system alone, the respiratory system and cardiovascular disease.
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 circulatory systems, relay anatomy, physiology and comparative forms from physiology and medical sources, route cardiovascular emergencies to emergency services, describe the named forms including horse, bird and fetal circulation, and distinguish the circulatory system from the lymphatic system alone, the respiratory system and cardiovascular disease.
The organ system that moves blood and lymph through the body, consisting in humans and other vertebrates of the heart, arteries, veins and capillaries in a closed system, with separate pulmonary and systemic circuits in mammals and birds, a single circuit in fish, and fetal circulation that bypasses the lungs through the foramen ovale and ductus arteriosus; many invertebrates such as insects have an open circulatory system in which haemolymph bathes organs, and William Harvey described blood circulation in 1628. Chest pain, stroke signs or severe bleeding need emergency services.
What it is for: Transporting oxygen, nutrients and wastes.
It can be explain anatomy and physiology; relay comparative forms; describe fetal circulation; route emergencies.
Distinguishing features
Closed or open systems
Double or single circuits
Heart pump
Fetal shunts
What it looks like
The heart and a branching network of vessels.
Physical character
Harvey s De Motu Cordis: 1628 year
adult blood volume: about 5 litres - varies with size
resting heart rate: about 60-100 beats per minute - adults
How it is recognised
Heart and blood vessel system
Circulatory system of birds, circulatory system of the horse, human circulatory system, open circulatory system, single circulatory system, fetal circulation
The lymphatic system returns fluid; the respiratory system exchanges gases; cardiovascular disease is pathology
