Human Circulatory System, Superior
Anatomical Schema Precision: Features a detailed relief mapping of the heart, lungs, liver, spleen, and kidneys, explicitly demonstrating the structural interconnection between major visceral organs and the central vascular trunk.
Vascular Differentiation: Utilizes a high-contrast, UV-resistant pigment system to distinguish between oxygenated arterial pathways and deoxygenated venous structures, ensuring immediate visual identification during high-occupancy lecture demonstrations.

Quick Answer: The human circulatory system model, listed as the Superior version, represents the heart and the main blood vessels of the body. It lets students trace arteries carrying blood away from the heart and veins returning it, and learn the names and positions of the major vessels.
Tracing the Vessels of the Body
A human circulatory system model lays out the vascular network so that the major vessels can be followed from end to end. From the heart, the aorta arches and descends, giving off the carotid arteries to the head, the subclavian arteries to the arms and branches to the gut and kidneys, before dividing into the iliac arteries that continue as the femoral arteries in the legs. On the return side, the jugular, subclavian and femoral veins lead back towards the superior and inferior venae cavae.
Beyond naming, the model supports ideas about how the system works: arteries branch into smaller arterioles and capillaries, where exchange with the tissues happens; veins carry blood at low pressure and rely on valves and muscle action; and the hepatic portal vein takes blood from the intestines to the liver before it returns to the heart.
The word ‘Superior’ in the listing is not explained in the product title. It may name a model grade in this range or point to an upper-body focus, so the layout and extent of the vessels shown should be confirmed before ordering.

Care & Handling
- Keep the human circulatory system model out of direct sunlight to protect the red and blue colour coding.
- Wipe with a soft damp cloth; do not use abrasive cleaners on painted vessels.
- Store it flat or upright as designed, and avoid stacking other items on it.
Applications
- Naming and locating the major arteries and veins in school and nursing anatomy
- Explaining the difference between arteries, veins and capillaries
- Showing pulse points where arteries run close to the surface, such as the radial and carotid
- Teaching the hepatic portal system and why blood from the gut passes through the liver first
Why Choose LabEquip
Nursing colleges and secondary schools buy this model for lessons in which students must name vessels and trace routes rather than just learn the heart. LabEquip lists it among its biology lab products, and the human circulatory blood chart is a useful wall companion. Use the contact page to ask about format and size.
Frequently Asked Questions
What is the difference between an artery and a vein?
Arteries carry blood away from the heart under higher pressure and have thick muscular walls. Veins carry blood towards the heart at low pressure, have thinner walls and often contain valves to prevent backflow.
Why are arteries coloured red and veins blue on models?
It is a teaching convention. Most arteries carry oxygen-rich blood and most veins oxygen-poor blood, although the pulmonary vessels reverse this. Real blood is red in both, only darker in veins.
What is the largest artery in the body?
The aorta. It leaves the left ventricle, arches over the heart and runs down through the chest and abdomen, giving off branches to every region of the body.
What does the hepatic portal vein do?
It carries blood from the stomach, intestines, pancreas and spleen to the liver. The liver processes absorbed nutrients and removes some toxins before this blood reaches the general circulation.
Where can a pulse be felt?
Wherever an artery runs close to the skin over something firm, for example the radial artery at the wrist, the carotid in the neck and the femoral in the groin. The model helps students locate these points.
What does Superior mean in this model’s name?
The listing does not define it. It may refer to the model grade or to the body region covered, and LabEquip will describe the layout of the vessels before you order.
