      Anatomy

    Correct Answer
    B. Homeostasis
    Explanation
    Homeostasis is the term used to describe the body's ability to maintain a stable internal environment despite changes in the external environment. In this example, it refers to the body temperature remaining constant at 37 degrees Celsius (98.6 degrees Fahrenheit) even when the person is swimming in water that is 22 degrees Celsius (72 degrees Fahrenheit). Homeostasis is achieved through various physiological mechanisms that regulate body temperature, such as sweating or shivering, to keep it within a narrow range necessary for optimal functioning of the body.

    Rate this question:

  • 6. 

    Word describing the lowering of blood glucose to normal after eathing a meal

    • A.

      Physiology

    • B.

      Homeostasis

    • C.

      Pathophysiology

    • D.

      Anatomy

    Correct Answer
    B. Homeostasis
    Explanation
    Homeostasis refers to the body's ability to maintain a stable internal environment. In the context of blood glucose levels, homeostasis is achieved by regulating the release and uptake of insulin. After eating a meal, blood glucose levels rise, triggering the release of insulin to help glucose enter cells for energy or storage. As a result, blood glucose levels are lowered back to normal, maintaining the body's equilibrium. Therefore, homeostasis is the appropriate word to describe the process of lowering blood glucose to normal after eating a meal.
