The Aorta Below is the subsystem that solves the equations for the aorta, the main artery of the heart. Emerging from the top of the heart, the aorta carries fresh blood from the hard-pumping left ventricle to all of the secondary arteries that branch out to all parts of the body. Simulink block diagram of the aorta.
Output resistance is equivalent to the combined input resistance of the arms, head, trunk, and legs.
It is assumed that there is no net heat gain or loss of heat. The weight of the aorta is roughly equivalent to the volume of blood, V , that it contains. The Goto and From blocks P4 and F5i-F8i are connections to other circulatory subsystems where the information flow is opposite of blood flow. F5i-F8i is used to keep this block diagram from being cluttered. V4 allows key output information to be passed directly to the Analysis Subsystem , where it can be managed in one central location.
