Urinary System Basic Quiz! Trivia MCQ - Quiz

The urinary system involves the kidneys, ureters, bladder, and urethra. The urinary system's objective is to rid the body of waste, control blood volume and blood pressure, balance electrolytes and metabolites, and regulate blood pH. The urinary tract is the body system for drainage. If you want to learn more about the urinary system, this is the quiz for you.


Questions and Answers
  • 1. 

    Brings blood into each kidney.

    • A.

      Artery

    • B.

      Vein

    • C.

      Ureter

    • D.

      Nephron

    Correct Answer
    A. Artery
    Explanation
    The correct answer is Artery because arteries are responsible for carrying oxygenated blood away from the heart to various parts of the body, including the kidneys. In the case of the kidneys, the renal artery brings oxygenated blood into each kidney, allowing for the filtration and removal of waste products from the blood.

  • 2. 

    Can get into the bladder and urethra and cause painful infections.

    • A.

      Bacteria

    • B.

      Kidney Stones

    • C.

      Kidney Disease

    • D.

      Cells

    Correct Answer
    A. Bacteria
    Explanation
    Bacteria can enter the bladder and urethra and cause painful infections. Bacterial infections in the urinary tract are common and can occur when bacteria from the digestive tract enter the urethra and travel up to the bladder. This can lead to symptoms such as pain, burning sensation during urination, frequent urination, and cloudy or bloody urine. Prompt treatment with antibiotics is necessary to clear the infection and prevent complications.

    Rate this question:

  • 3. 

    When salts and wastes collect inside the kidney it forms?

    • A.

      Kidney Disease

    • B.

      Urine

    • C.

      Bacteria

    • D.

      Kidney Stones

    Correct Answer
    D. Kidney Stones
    Explanation
    When salts and wastes accumulate inside the kidney, they can crystallize and form solid masses called kidney stones. These stones can vary in size and can cause severe pain and discomfort when they pass through the urinary tract. Kidney stones are typically composed of calcium, oxalate, or uric acid, and their formation can be influenced by factors such as dehydration, certain medical conditions, and dietary habits. Treatment options for kidney stones include medication, lifestyle changes, and in some cases, surgical intervention.

    Rate this question:

  • 4. 

    As the water content of the blood drops, the salivary glands produce less?

    • A.

      Evaporation

    • B.

      Dioretics

    • C.

      Antidioretic

    • D.

      Saliva

    Correct Answer
    D. Saliva
    Explanation
    When the water content of the blood drops, the salivary glands produce less saliva. This is because saliva is primarily composed of water, and when there is a decrease in the overall water content in the body, the salivary glands are unable to produce a sufficient amount of saliva. Saliva plays a crucial role in lubricating the mouth, aiding in digestion, and maintaining oral health. Therefore, a decrease in saliva production can lead to dry mouth, difficulty in swallowing, and other related issues.

    Rate this question:

  • 5. 

    The kidneys react by following more water to stay in the nephrons and leave the body as?

    • A.

      Fluids

    • B.

      Urine

    • C.

      Hormones

    • D.

      Sweat

    Correct Answer
    B. Urine
    Explanation
    When the kidneys react by following more water to stay in the nephrons, it means that they are reabsorbing water from the filtrate in order to maintain the body's water balance. This process occurs in the renal tubules of the nephrons. The water that is reabsorbed combines with waste products, such as urea and excess salts, to form urine. Therefore, urine is the correct answer as it is the final product that is excreted from the body through the urinary system.

    Rate this question:

  • 6. 

    What is the process of removing waste products from the body?

    • A.

      Excretion

    • B.

      Body Cells

    • C.

      Carbon Dioxide

    • D.

      Kidney

    Correct Answer
    A. Excretion
    Explanation
    Excretion is the process of removing waste products from the body. It involves the elimination of metabolic waste such as carbon dioxide, urea, and excess water through various organs and systems, including the kidneys, lungs, skin, and digestive system. The kidneys play a crucial role in excretion by filtering the blood and removing waste products in the form of urine. Overall, excretion is essential for maintaining homeostasis and ensuring the proper functioning of the body's systems.

  • 7. 

    Sometimes, salts and other collects inside the kidneys and form kidney stones.

    Correct Answer
    waste
    Explanation
    The statement suggests that salts and other substances can accumulate in the kidneys and result in the formation of kidney stones. Kidney stones are solid masses made up of waste materials that have not been properly filtered and excreted by the kidneys. These waste materials can include minerals, salts, and other substances that are normally dissolved in urine. When these substances become concentrated and form crystals, they can stick together and form kidney stones. Therefore, the presence of waste materials in the kidneys can lead to the formation of kidney stones.

    Rate this question:

  • 8. 

    Damage can prevent normal kidney functioning and can lead to kidney disease.

    Correct Answer
    Explanation
    Damage to the kidneys can interfere with their ability to filter waste products and excess fluids from the blood, leading to kidney disease. The kidneys play a crucial role in maintaining the balance of electrolytes, regulating blood pressure, and producing hormones that stimulate red blood cell production. When the kidneys are damaged, these functions can be impaired, resulting in a buildup of waste products and fluid in the body. Over time, this can lead to the development of kidney disease, which may require medical intervention such as dialysis or a kidney transplant to manage.

    Rate this question:

  • 9. 

    Some beverages contain caffeine, which is a?.

    Correct Answer
    diuretic
    Explanation
    Caffeine is a diuretic because it increases urine production and promotes the excretion of water from the body. This can lead to increased frequency of urination and potentially contribute to dehydration if not enough fluids are consumed.

    Rate this question:

  • 10. 

    The _______contains the organs that remove waste products from your blood.

    Correct Answer
    urinary system
    Explanation
    The urinary system is responsible for removing waste products from the blood. It consists of organs such as the kidneys, ureters, bladder, and urethra. The kidneys filter waste products, excess water, and toxins from the blood, producing urine. The urine is then transported through the ureters to the bladder, where it is stored until it is eliminated from the body through the urethra. Therefore, the urinary system is the correct answer as it performs the function of removing waste products from the blood.

    Rate this question:

  • 11. 

    The_________are a pair of organs that constantly clean the blood.

    Correct Answer
    kidneys
    Explanation
    The kidneys are a pair of organs that constantly clean the blood. They filter waste products, excess water, and toxins from the bloodstream, producing urine as a result. The kidneys also help regulate the body's fluid balance, electrolyte levels, and blood pressure. Their continuous filtration process ensures that the blood remains clean and free from harmful substances, maintaining overall health and well-being.
