Functional Heart and Circulatory System
This amazing working model will bring your lecture to life! A complete
schematic model of the human circulatory system with “blood” (coloured
water) that flows through transparent veins, arteries, capillaries and heart
chambers. This model’s special design portrays venous blood, a deep red-
dish purple and arterial blood, a bright red to give visual reinforcement to
the oxygenation and deoxygenation of haemoglobin as it travels the body’s
vascular network. Mounted on a baseboard with support legs and supplied
with teacher’s guide, red dye and syringe for refilling the system.

™ Artery and Vein
The model shows a medium sized muscular artery with two adjacent veins
from the antebrachial area with adjoining fat tissue and muscle enlarged
14 times. The model illustrates the reciprocal anatomical relationship of
artery and vein and the basic functional techniques of the venous valves
(“valve function” and “muscle pump”). The left vein and the middle artery
are fenestrated in the upper anterior segment, revealing the various layers
of the wall structure in a cross and longitudinal section and in top view.
The right vein is opened throughout in the anterior segment, revealing the
orifice of a feeder vein and two venous valves, i.e. “flap valves” formed by
a duplication of the tunica intima. On the rear of the model, the relief of
two veins is shown to illustrate the functional aspect of the venous valves.
Supplied on base.

Hypertension Model, 7-part
This model shows the harmful effects of hypertension on the most suscep-
tible organs. It consists of scaled down depictions of: Brain, Eye, 2-part
heart, 2-part kidney, an enlarged artery.

Arteriosclerosis Model, with
Cross Section of Artery, 2-part
With the help of this model doctors
can explain changes in the blood
vessels due to arteriosclerosis. A
horizontally dissected artery fork
is depicted with arteriosclerotic
changes in four different stages,
from slightly sedimented to a com-
pletely clogged vessel. On stand.

Venous Valves in Operation
According to Bischof
Venous valves ensure that the
blood in the veins flows back to
the heart against gravity despite
the low pressure. If the blood flows
“backwards”, the valves close the
veins like check valves. This mecha-
nism can be demonstrated wonder-
fully using our model made of
transparent acrylic; the “venous
valves” open just like the vascular
system of vertebrates. Only the
blood flow is not shown. Instead,
the model demonstrates this with
a stream of air. You will be able to
show your pupils the blood flow
with opened valves, and the
mounting backlog when the valves
are closed.
