  • 2. 

    Osmoreceptors detect changes in

    • Blood pressure

    • Osmotic pressure

    • Blood viscosity

    Correct Answer
    A. Osmotic pressure
    Explanation
    Osmoreceptors are sensory cells that detect changes in the osmotic pressure of the body's fluids. Osmotic pressure refers to the concentration of solutes in a solution, and it plays a crucial role in maintaining the balance of fluids in the body. When osmotic pressure increases, it indicates a higher concentration of solutes in the fluids, leading to a potential risk of dehydration. Osmoreceptors detect this change and trigger physiological responses to regulate water balance and maintain homeostasis. Therefore, osmotic pressure is the correct answer as it accurately describes the function of osmoreceptors.

    Homeostasis is also termed a dynamic equilibrium because

    • The body maintains an internal balance, within fluctuating limits

    • In homeostasis parts of the system change but the overall system stays constant

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The term "dynamic equilibrium" is used to describe homeostasis because it involves the body's ability to maintain internal balance within fluctuating limits. In homeostasis, different parts of the system may change, but the overall system remains constant. Therefore, all of the given statements are correct explanations for why homeostasis is also termed a dynamic equilibrium.

    pH balance is maintained by:

    • Kidneys

    • Liver

    • Hypothalamus

    Correct Answer
    A. Kidneys
    Explanation
    The kidneys play a crucial role in maintaining the pH balance of the body. They help regulate the levels of acids and bases in the blood by filtering out excess acids or bases and excreting them through urine. The kidneys also reabsorb bicarbonate ions, which act as a buffer to maintain the pH within a normal range. This process helps to prevent the blood from becoming too acidic or too alkaline, ensuring that the body's pH remains balanced.

    What component of all homeostatic control systems relays the information back to the appropriate regulator?

    • Monitor

    • Sensor

    • Regulator

    • Coordinating center

    Correct Answer
    A. Coordinating center
    Explanation
    The coordinating center is the component of all homeostatic control systems that relays the information back to the appropriate regulator. It acts as a central hub, receiving input from the monitor and sensor components, and then sending signals to the regulator to initiate the necessary adjustments to maintain homeostasis. The coordinating center ensures that the feedback loop is completed and that the appropriate responses are made to maintain the body's internal balance.

    How would the body respond to an increased environmental temperature?

    • Hairs on body erect

    • Sweating

    • Shivering

    • Dilation of blood vessels

    • Only A and D are correct

    Correct Answer
    A. Only A and D are correct
    Explanation
    When the environmental temperature increases, the body responds by erecting hairs on the body to create a layer of insulation, reducing heat loss. Additionally, the body dilates blood vessels to allow more blood flow near the surface of the skin, promoting heat dissipation. Sweating is not a response to an increased environmental temperature as it is a mechanism to cool down the body when it is overheated. Shivering, on the other hand, is a response to a decreased environmental temperature to generate heat. Therefore, the correct answer is that only A (hairs on body erect) and D (dilation of blood vessels) are correct responses to an increased environmental temperature.
