@Fructose Additionally, the notion of maintaining a constant equilibrium in a complex system is open to question. The system is in a state of constant fluctuation, moving in and out of equilibrium. Consequently, the assumption of true equilibrium may be invalid. The equilibrium of a complex system can be readily disrupted by a multitude of factors.
With regard to CO2, it seems plausible that it functions as a stock-flow principle, analogous to a process such as pregnenolone from a technical standpoint. The body accumulates CO₂ to an optimal level, thereby facilitating the attainment of equilibrium within the system. Furthermore, evidence suggests that CO₂ is sequestered in bones, which lends support to the hypothesis that the body is constantly striving to maintain an optimal level of CO₂ within the system.
