Final answer:
The answer is A. True, since homeostasis represents the dynamic establishment of a stable internal environment that is critical for the human body to function correctly.
Step-by-step explanation:
The correct option : a
Homeostasis refers to the physiological balance within the body, which is essential for maintaining life and optimal functioning of the body. This process involves maintaining various variables such as body temperature, blood pressure, pH levels, fluid balance, and electrolyte concentrations within a narrow, healthy range. Vital body systems constantly monitor these conditions and respond to deviations from the equilibrium, usually by way of negative feedback loops.
For instance, if blood glucose levels rise, the body secretes insulin to lower these levels back to the normal range. Cells, tissues, organs, and organ systems work synergistically to achieve homeostasis, adjusting their functions in response to environmental and internal changes. Disruption to homeostasis may lead to illness or disease and can be life-threatening. Therefore, homeostasis is a state of dynamic equilibrium that is essential for the body to function correctly, highlighting the truth of the initial statement.
