Simple revision quiz on homeostasis


Questions and Answers
  • 1. 

    The kidneys filter out of your blood: (choose all correct answers)

    • A.

      Water

    • B.

      Glucose

    • C.

      Urea

    • D.

      Salt

    • E.

      None of the above

    Correct Answer(s)
    A. Water
    B. Glucose
    C. Urea
    D. Salt
    Explanation
    The kidneys play a crucial role in filtering waste products from the blood. Water, glucose, urea, and salt are all substances that can be filtered out by the kidneys. Water is essential for maintaining proper hydration levels in the body, while glucose is a sugar that needs to be regulated for energy balance. Urea is a waste product produced by the breakdown of proteins, and salt is an electrolyte that needs to be balanced in the body. Therefore, the correct answer is water, glucose, urea, and salt.

    Rate this question:

  • 2. 

    What do the kidneys put back into your blood

    • A.

      All glucose

    • B.

      Some glucose

    • C.

      All water

    • D.

      As much water needed

    • E.

      All salt

    • F.

      As much salt needed

    • G.

      All urea

    • H.

      No urea

    Correct Answer(s)
    A. All glucose
    D. As much water needed
    F. As much salt needed
    H. No urea
    Explanation
    The kidneys filter waste products from the blood, but they also reabsorb certain substances that are necessary for the body. Glucose is an important source of energy, so the kidneys put back all the glucose into the blood. Water is essential for maintaining proper hydration, so the kidneys reabsorb as much water as needed to maintain the body's fluid balance. Salt is important for maintaining electrolyte balance, so the kidneys reabsorb as much salt as needed. Urea is a waste product that is filtered out by the kidneys and excreted in urine, so the kidneys do not put back any urea into the blood.

    What one (1) of the four (4) ways of removing water from the body (spelling matters)

    Correct Answer(s)
    urine
    sweat
    faeces
    breathing
    Explanation
    The correct answer includes all four ways of removing water from the body: urine, sweat, faeces, and breathing. Urine is produced by the kidneys and eliminates waste products, including water, from the body. Sweat is produced by sweat glands and helps regulate body temperature by releasing water and salts. Faeces, or solid waste, contains water that is excreted from the body through the digestive system. Breathing also plays a role in water removal as water vapor is exhaled from the lungs.

  • 4. 

    What is the human body's set point temperature (units matter)

    Correct Answer(s)
    37 degrees celcius
    thirty-seven degrees celcius
    thirty seven degrees celcius
    Explanation
    The human body's set point temperature is 37 degrees Celsius. This is the temperature at which the body functions optimally and maintains homeostasis. It is important for various physiological processes such as enzyme activity, metabolism, and immune function. The body regulates its temperature through mechanisms like sweating and shivering to maintain this set point temperature.

    What organ controls blood glucose levels

    • A.

      Large Intestine

    • B.

      Brain

    • C.

      Lungs

    • D.

      Pancreas

    Correct Answer
    D. Pancreas
    Explanation
    The pancreas is responsible for controlling blood glucose levels. It produces and releases insulin, a hormone that helps regulate the amount of glucose in the blood. When blood glucose levels are high, the pancreas releases insulin to lower them. Conversely, when blood glucose levels are low, the pancreas releases glucagon, which raises them. This delicate balance maintained by the pancreas is crucial for overall health and preventing conditions like diabetes.

    Rate this question:

  • 6. 

    What does insulin do

    • A.

      Makes us sweat

    • B.

      Makes us shiver

    • C.

      Moves glucose into cells

    • D.

      Moves glucose out of cells

    Correct Answer
    C. Moves glucose into cells
    Explanation
    Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. When insulin is released into the bloodstream, it binds to receptors on the surface of cells, allowing glucose to enter the cells from the bloodstream. This process helps to lower blood sugar levels and provide cells with the energy they need for various functions. Therefore, the correct answer is that insulin moves glucose into cells.

    What are the two types of diabetes called (separate types by using 'and')

    Correct Answer
    type 1 and type 2
    type one and type two
    Explanation
    The two types of diabetes are referred to as type 1 and type 2. They are notated as "type 1 and type 2" or "type one and type two".

    What are the four (4) things critical to life

    • A.

      Water

    • B.

      Salt

    • C.

      Glucose

    • D.

      Temperature

    • E.

      Watching Star Wars all day long

    Correct Answer(s)
    A. Water
    B. Salt
    C. Glucose
    D. Temperature
    Explanation
    The four things critical to life are water, salt, glucose, and temperature. Water is essential for various bodily functions and maintaining hydration. Salt helps in maintaining electrolyte balance and nerve function. Glucose provides energy for cellular activities. Temperature regulation is crucial for enzyme function and overall bodily processes.

    Homeostasis means controlling variables to maintain a constant internal environment

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Homeostasis refers to the ability of an organism to maintain a stable internal environment despite changes in the external environment. This process involves regulating various variables such as body temperature, blood sugar levels, and pH levels within a narrow range. By doing so, the body ensures that its cells can function optimally. Therefore, the statement "Homeostasis means controlling variables to maintain a constant internal environment" is true.
