Trivia: Excretory System Quiz! Test - Quiz


What do you know about the excretory system? Some things within our system would pose a health threat if left without being disposed of. The excretory system is made up of kidneys, large intestine, liver, skin, and lungs. For one, the kidneys are expected to filter blood from the urine, and if there is blood in one's urine, they need to see the doctor. What other issues can attack the organs in this system, and what might be the problem? Take this quiz and refresh your understanding of the system.


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 maintaining homeostasis in the body. It eliminates waste products, such as urine and sweat, which helps to regulate the balance of fluids and chemicals in the body. Additionally, the excretory system filters and removes toxins from the bloodstream, ensuring that the body's internal environment remains stable. By performing these functions, the excretory system helps to maintain the overall balance and stability of the body's internal conditions.

    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 of removing wastes from the body. It involves the elimination of metabolic waste products, such as carbon dioxide, urea, and excess water, through various organs and systems, including the kidneys, lungs, and skin. This process is essential for maintaining homeostasis and preventing the buildup of harmful substances in the body.

    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 are responsible for filtering waste products and excess water from the blood to produce urine. The kidneys also help regulate the body's electrolyte balance and blood pressure. The other options mentioned (lungs, skin, and liver) are also involved in excretion to some extent, but the kidneys play the most vital role in removing waste materials from the body.

    What filters the blood in this system?

    • A.

      Kidneys

    • B.

      Skin

    • C.

      Lungs

    • D.

      Bladder

    Correct Answer
    A. Kidneys
    Explanation
    The kidneys are responsible for filtering the blood in the body. They remove waste products, excess water, and toxins from the blood, producing urine as a result. The kidneys play a vital role in maintaining the balance of electrolytes, regulating blood pressure, and producing hormones that stimulate red blood cell production. The other options listed, such as the skin, lungs, and bladder, do not have the primary function of filtering the blood.

    How many organs are included in the excretory system?

    • A.

    • C.

      4

    • D.

      5

    Correct Answer
    B. 3
    Explanation
    The excretory system is responsible for eliminating waste from the body. It includes three main organs: the kidneys, which filter waste from the blood and produce urine, the bladder, which stores urine, and the urethra, which carries urine out of the body. These three organs work together to remove waste products and maintain the body's balance of fluids and electrolytes.

    UTIs are more common in females.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    UTIs (Urinary Tract Infections) are more common in females due to anatomical differences. The female urethra is shorter, allowing bacteria to travel more easily to the bladder. Additionally, the close proximity of the urethra to the anus increases the risk of bacterial contamination. Hormonal changes during pregnancy and menopause also contribute to a higher risk. Therefore, it is true that UTIs are more common in females.

    What organ does a Kidney infection make swell?

    • A.

      Bladder

    • B.

      Heart

    • C.

      Lungs

    • D.

      Kidney

    Correct Answer
    D. Kidney
    Explanation
    A kidney infection causes swelling in the kidney. Kidney infections, also known as pyelonephritis, occur when bacteria enter the kidneys and cause an infection. This infection leads to inflammation and swelling of the kidney tissue. Symptoms of a kidney infection may include pain in the lower back or side, fever, frequent urination, and blood in the urine. Prompt treatment with antibiotics is necessary to prevent complications and further damage to the kidneys.

    Other than surgery how else can kidney stones be removed?

    • A.

      Ultrasounds

    • B.

      Coughing them up

    Correct Answer
    A. Ultrasounds
    Explanation
    Kidney stones can be removed using ultrasounds. This non-invasive procedure, known as extracorporeal shock wave lithotripsy (ESWL), involves using high-energy sound waves to break the stones into smaller pieces. These smaller pieces can then pass out of the body through urine. ESWL is a commonly used method for treating kidney stones, especially for smaller stones that are located in the kidney or upper ureter. It is a preferred alternative to surgical procedures as it does not require any incisions or anesthesia, resulting in a shorter recovery time and fewer complications.
