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

What the second pass must settle

  • Should species-specific circulatory entries be separate?
  • How should physiology sources be linked?
  • Should fetal circulation be a separate entry?
