Five clear plastic, perfectly crafted demonstration models are made for educational purposes, with special attention being paid to the accuracy and detail of the complete cardiovascular system. Each has an identical heart, beating at a controlled steady 73 bpm, delivering 5 litres/min total systemic flow round the loop. All other details are completely uniform APART FROM the five aortas and principal arteries, large and small, as far down as the brachial arteries.
For interest's sake, one of the models has perfect normal (i.e., young and healthy) elasticity for its aorta and arteries.
Two others have theirs made of (a) much less compliant plastic and (b) much more compliant plastic.
The fourth has its aorta and arteries made from virtually non-compliant plastic, and (you guessed!) the fifth has its made of something like condom latex..
So, five perfect, uniform models, all having blood ejected from the ventricle at the same pressure.
What will the brachial B/P's be?
