This commit re-implements several critical physiological feedback loops that were lost, enhancing the realism of the simulation.
The following systems have been added:
1. **Full Digestive Loop:**
- The Gallbladder now has a `releaseBile` method, triggered by chyme in the intestines.
- The Pancreas has a `releaseEnzymes` method, also triggered by chyme.
- The Intestines' digestion logic has been updated to be more effective when bile and enzymes are present.
2. **Autonomic Nervous System Control:**
- The Brain now monitors blood gas (O2/CO2) and blood pressure levels.
- It dynamically adjusts the respiration rate of the Lungs via a new `setRespirationRate` method in response to blood gas changes.
- It controls the heart rate via a new `setHeartRate` method in response to blood pressure changes, simulating the baroreceptor reflex.
- The previous hardcoded rate control logic in the Lungs and Heart has been removed.
3. **Kidney Blood Pressure Regulation (RAAS):**
- A simplified Renin-Angiotensin-Aldosterone System has been implemented.
- The Kidneys now secrete renin in response to low blood pressure.
- The Liver produces a constant supply of angiotensinogen.
- A new `angiotensin_au` value in the Blood struct is calculated in the main patient update loop.
- This hormone now acts as a vasoconstrictor, directly affecting the blood pressure calculation in the Heart.
These changes significantly increase the complexity and fidelity of the medical simulation by modeling the interconnectedness of the major organ systems.
