Questions and Answers
  • 1. 

    What is the function of the excretory system?

    • A.

      Maintain homeostasis

    • B.

      Protect the organs

    • C.

      Helps you move

    • D.

      Grows hair

    Correct Answer
    A. Maintain homeostasis
    Explanation
    The excretory system is responsible for removing waste products and excess substances from the body, such as urine, sweat, and carbon dioxide. By eliminating these waste products, the excretory system helps maintain the balance of fluids, electrolytes, and pH levels in the body, which is crucial for homeostasis. Therefore, the function of the excretory system is to maintain homeostasis by regulating the composition and volume of body fluids.

    Rate this question:

  • 2. 

    What organs are in the excretory system?

    • A.

      Kidneys, lungs, skin, brain, bladder

    • B.

      Liver, lungs, skin, heart, bladder

    • C.

      Kidneys, liver, lungs, skin, bladder

    • D.

      Kidneys, liver, lungs, heart, skin

    Correct Answer
    C. Kidneys, liver, lungs, skin, bladder
    Explanation
    The excretory system is responsible for eliminating waste from the body. The organs involved in this system are the kidneys, liver, lungs, skin, and bladder. The kidneys filter waste from the blood and produce urine. The liver processes and eliminates toxins from the body. The lungs remove carbon dioxide and other waste gases through respiration. The skin eliminates waste through sweat glands. The bladder stores and eliminates urine from the body. Therefore, the correct answer is kidneys, liver, lungs, skin, bladder.

    Rate this question:

  • 3. 

    The excretory systems regulates the ______ composition by removing wastes.

    • A.

      Mechanical

    • B.

      Chemical

    • C.

      Toxic

    • D.

      Blood

    Correct Answer
    B. Chemical
    Explanation
    The excretory system regulates the chemical composition of the body by removing waste products. This includes substances such as urea, carbon dioxide, and excess salts. These waste products are filtered out of the blood by the kidneys and then excreted in the form of urine. The excretory system plays a crucial role in maintaining the balance of chemicals and electrolytes in the body, ensuring that harmful substances are removed and the body's internal environment remains stable.

    Rate this question:

  • 4. 

    The liver _____ toxic waste in blood.

    • A.

      Increases

    • B.

      Removes

    • C.

      Reduces

    • D.

      Puts

    Correct Answer
    B. Removes
    Explanation
    The liver is responsible for removing toxic waste from the blood. It acts as a filter and detoxifies various harmful substances, ensuring that the blood circulating throughout the body remains clean and free from toxins.

    Rate this question:

  • 5. 

    The removal of wastes in the body is known as ____.

    • A.

      Secretion

    • B.

      Removal

    • C.

      Subtract

    • D.

      Excretion

    Correct Answer
    D. Excretion
    Explanation
    Excretion is the process by which waste products, such as urine, feces, and sweat, are eliminated from the body. It involves the removal of metabolic waste, toxins, and excess substances that are no longer needed by the body. Through various organs and systems, such as the kidneys, liver, lungs, and skin, excretion plays a vital role in maintaining the body's homeostasis and preventing the buildup of harmful substances.

    Rate this question:

  • 6. 

    What is the primary organ in the excretory system?

    • A.

      Kidneys

    • B.

      Lungs

    • C.

      Skin

    • D.

      Liver

    Correct Answer
    A. Kidneys
    Explanation
    The kidneys are the primary organ in the excretory system. They play a crucial role in filtering waste products and excess fluids from the blood to form urine. The urine is then transported to the bladder for elimination. The kidneys also regulate the body's electrolyte balance, blood pressure, and acid-base balance. The other options listed, such as the lungs, skin, and liver, do have some excretory functions, but they are not the primary organs responsible for excretion in the human body.

    Rate this question:

  • 7. 

    During excretion carbon dioxide and water is removed by which organ?

    • A.

      Kidneys

    • B.

      Liver

    • C.

      Skin

    • D.

      Lungs

    Correct Answer
    D. Lungs
    Explanation
    During excretion, carbon dioxide and water are removed from the body. The lungs play a crucial role in this process by eliminating carbon dioxide and water vapor during exhalation. As we breathe in oxygen, our cells utilize it to produce energy and release carbon dioxide as a waste product. The lungs then remove this carbon dioxide from the bloodstream and release it into the air when we exhale. Therefore, the correct answer is lungs.

    Rate this question:

  • 8. 

    What is the function of the skin in this system?

    • A.

      Peal

    • B.

      Protect the body

    • C.

      Grow hair

    • D.

      Sweat

    Correct Answer
    D. Sweat
    Explanation
    The function of the skin in this system is to sweat. The skin produces sweat as a way to regulate body temperature. When the body gets too hot, sweat is released through the pores of the skin, which then evaporates and cools down the body. This helps to maintain a stable internal body temperature and prevent overheating.

    Rate this question:

  • 9. 

    What is the function of the kidneys in the excretory system?

    • A.

      Sweat

    • B.

      Filter blood

    • C.

      Remove carbon dioxide

    • D.

      Grow hair

    Correct Answer
    B. Filter blood
    Explanation
    The kidneys play a crucial role in the excretory system by filtering waste products and excess water from the bloodstream. They help maintain the balance of fluids and electrolytes in the body, regulate blood pressure, and remove toxins and metabolic waste. By filtering the blood, the kidneys ensure that waste products are eliminated through urine, while essential substances like water, electrolytes, and nutrients are retained and returned to the bloodstream.

    Rate this question:

  • 10. 

    What filters the blood in this system?

    • A.

      Kidneys

    • B.

      Skin

    • C.

      Lungs

    • D.

      Bladder

    Correct Answer
    A. Kidneys
    Explanation
    The kidneys filter the blood in this system. They are responsible for removing waste products, excess water, and toxins from the blood, which are then excreted as urine. The kidneys play a crucial role in maintaining the body's fluid balance, regulating blood pressure, and producing hormones that stimulate red blood cell production.
