Urinary System Anatomy Quiz - Quiz

Can you pass this urinary system anatomy quiz? The urinary system is tasked with removing liquid waste from the blood in the form of urine and producing erythropoietin, a hormone that aids the formation of red blood cells. The system plays a big role in regulating blood pressure. Test what else you understand about the system by taking the test below. Good luck to you with this test, and have fun!


Questions and Answers
  • 1. 

    Components of the urinary system include

    • A.

      2 kidneys

    • B.

      2 ureters

    • C.

      1 urinary bladder

    • D.

      1 urethra

    • E.

      All are correct

    Correct Answer
    E. All are correct
    Explanation
    The urinary system is composed of several components, including two kidneys, two ureters, one urinary bladder, and one urethra. Each of these structures plays a vital role in the excretion of waste products from the body. The kidneys filter the blood and produce urine, which is then transported through the ureters to the urinary bladder. The bladder stores the urine until it is expelled through the urethra during urination. Therefore, all of the given options correctly represent the components of the urinary system.

    Rate this question:

  • 2. 

    Which is not a function of the kidneys?           

    • A.

      Production and release of calcitriol and erythropoietin

    • B.

      Storage of urine

    • C.

      Regulation of blood composition and pH

    • D.

      Regulation of blood volume and pressure

    • E.

      Maintenance of blood osmolarity

    Correct Answer
    B. Storage of urine
    Explanation
    The kidneys perform several important functions in the body, including the production and release of calcitriol and erythropoietin, regulation of blood composition and pH, regulation of blood volume and pressure, and maintenance of blood osmolarity. However, storage of urine is not a function of the kidneys. Urine is produced in the kidneys and then transported to the bladder for storage until it is eliminated from the body through urination. Therefore, the correct answer is storage of urine.

    Rate this question:

  • 3. 

    If your pee is _______, it means you are hydrated.

    • A.

      Yellow

    • B.

      Colorless

    • C.

      White

    • D.

      Red

    • E.

      Brown

    Correct Answer
    A. Yellow
    Explanation
    If your pee is yellow, it means you are hydrated. The color of urine can vary depending on the concentration of waste products and the amount of water in the body. When a person is well-hydrated, their urine is usually pale yellow or straw-colored. This indicates that there is a good balance of water in the body and the kidneys are functioning properly to remove waste products.

    Rate this question:

  • 4. 

    ________ is not found in urinary system.

    • A.

      Bladder

    • B.

      Urethra

    • C.

      Ureters

    • D.

      Both B & C

    • E.

      Rectum

    Correct Answer
    E. Rectum
    Explanation
    The rectum is not found in the urinary system. The urinary system consists of organs such as the bladder, urethra, and ureters, which are responsible for the production, storage, and elimination of urine. The rectum, on the other hand, is part of the digestive system and is responsible for the storage and elimination of solid waste. Therefore, the rectum is not included in the urinary system.

    Rate this question:

  • 5. 

    The urinary system helps to

    • A.

      Keep the body dry

    • B.

      Keep the body wet

    • C.

      Get rid of the waste.

    • D.

      Keep the waste

    • E.

      None of these

    Correct Answer
    C. Get rid of the waste.
    Explanation
    The urinary system helps to get rid of waste. This system consists of the kidneys, ureters, bladder, and urethra, which work together to filter waste products from the blood and eliminate them in the form of urine. The kidneys filter waste and excess water from the blood, while the ureters transport the urine to the bladder. The bladder stores the urine until it is expelled through the urethra. This process helps to maintain the body's fluid balance and remove harmful substances from the body.

    Rate this question:

  • 6. 

    Urine is stored in ______.

    • A.

      Rectum

    • B.

      Kidney 

    • C.

      Heart

    • D.

      Bladder

    • E.

      None of these

    Correct Answer
    D. Bladder
    Explanation
    The correct answer is bladder. The bladder is a muscular organ located in the lower abdomen that stores urine before it is eliminated from the body. It receives urine from the kidneys through the ureters and expands to accommodate the increasing volume of urine. When the bladder is full, it sends signals to the brain, triggering the urge to urinate.

    Rate this question:

  • 7. 

    ________ carry urine from kidneys to bladder.

    • A.

      Tubulars

    • B.

      Rectum

    • C.

      Both A & B

    • D.

      None

    • E.

      Ureters

    Correct Answer
    E. Ureters
    Explanation
    The correct answer is Ureters. Ureters are thin tubes that carry urine from the kidneys to the bladder. They play a crucial role in the urinary system by transporting urine, which is produced in the kidneys, to the bladder for storage until it is eliminated from the body.

    Rate this question:

  • 8. 

    Each of the following is a waste product normally secreted by the kidneys except  

    • A.

      Urea

    • B.

      Bilirubin

    • C.

      Glucose

    • D.

      Ammonia

    • E.

      Creatine

    Correct Answer
    C. Glucose
    Explanation
    The kidneys are responsible for filtering waste products from the blood and excreting them in the urine. Urea, bilirubin, ammonia, and creatine are all waste products that are normally secreted by the kidneys. However, glucose is not considered a waste product and is typically reabsorbed by the kidneys to maintain blood glucose levels. Therefore, the correct answer is glucose.

    Rate this question:

  • 9. 

    The kidneys

    • A.

      Are retroperitoneal and are attached to the abdominal wall.

    • B.

      Are partially protected by ribs 6-9

    • C.

      Are surrounded by capsules of epithelial tissue

    • D.

      Are protected from mechanical trauma by a thick layer of loose CT

    • E.

      Have concave lateral borders.

    Correct Answer
    A. Are retroperitoneal and are attached to the abdominal wall.
    Explanation
    The kidneys are retroperitoneal, which means they are located behind the peritoneum, a membrane that lines the abdominal cavity. They are attached to the abdominal wall by connective tissue and are not covered by the peritoneum. This positioning helps to protect the kidneys from external trauma and provides stability to their location within the body.

    Rate this question:

  • 10. 

    The layer of the kidney superficial to the renal pyramids but deep to the renal capsule is the

    • A.

      Renal pelvis

    • B.

      Renal pyramid

    • C.

      Renal medulla

    • D.

      Renal lobe

    • E.

      Renal papilla

    Correct Answer
    C. Renal medulla
    Explanation
    The layer of the kidney that is superficial to the renal pyramids but deep to the renal capsule is the renal medulla. The renal medulla is located between the renal cortex (which includes the outer layer of the kidney) and the renal pelvis (which is the innermost part that collects urine before it enters the ureter). The renal pyramids are part of the renal medulla, and they contain the nephron tubules responsible for urine formation.
