What term describes the ability to keep body systems functioning in a steady state?

1. Coagulation

2. Articulation

3. Metabolism

4. Homeostasis

The correct answer is: Homeostasis

The ability to keep body systems functioning in a steady state is referred to as homeostasis. This term describes the dynamic equilibrium maintained by biological systems to promote stability in response to changing external conditions. For instance, the human body regulates temperature, pH levels, and blood pressure to ensure optimal functioning. These processes involve various feedback mechanisms that detect changes and initiate responses to correct any deviations from the desired state. In context, coagulation refers to the process of blood clotting and is more focused on preventing blood loss rather than maintaining overall body stability. Articulation pertains to the connection and movement between bones at joints, which is unrelated to systemic regulation. Metabolism involves all biochemical processes that occur within the body, including energy production and utilization, but it does not specifically address the maintenance of stable internal conditions. Therefore, homeostasis is the most fitting term for describing the ongoing processes that keep bodily systems in balance.
