Models of physiological control systems are valuable aids to the medical profession. A model of the heart-rate control system is shown in Figure P1.9 [23, 24, 48]. This model includes the processing of the nerve signals by the brain. The heart-rate control system is, in fact, a multivariate system, and the variables x, y, w, v, z, and u are vector variables. In other words, the variable x represents many heart variables x1, x2,..., xn. Examine the model of the heart-rate control system and add or delete blocks, if necessary. Determine a control system model of one of the following physiological control systems:
1. Respiratory control system
2. Adrenaline control system
3. Human arm control system
4. Eye control system
5. Pancreas and the blood-sugar-level control system
6. Circulatory system
