Questions and Answers
  • 1. 

    The Urinary system consists of____?

    • A.

      Kidney, two ureters, bladder

    • B.

      Two kidneys, two uriteres, bladder and urethra

    • C.

      Two kidneys, uriter, bladder, and two urethras

    • D.

      Two kidneys, two uriters, bladder

    Correct Answer
    B. Two kidneys, two uriteres, bladder and urethra
    Explanation
    The urinary system consists of two kidneys, which filter waste products from the blood and produce urine. The urine then travels through two ureters, which are tubes that connect the kidneys to the bladder. The bladder stores urine until it is ready to be eliminated from the body through the urethra. Therefore, the correct answer is two kidneys, two ureters, bladder, and urethra.

    Rate this question:

  • 2. 

    Nephrons in the kidneys are responsible for____? 

    • A.

      Continueally regulating water,salts,glucose,urea and other minerals in the blood.

    • B.

      Remove excess electrolytes and other products that exceed the amount tolerated by the body.

    • C.

      Maintaining homeostasis.

    Correct Answer(s)
    A. Continueally regulating water,salts,glucose,urea and other minerals in the blood.
    B. Remove excess electrolytes and other products that exceed the amount tolerated by the body.
    C. Maintaining homeostasis.
    Explanation
    The nephrons in the kidneys are responsible for continuously regulating water, salts, glucose, urea, and other minerals in the blood. They also remove excess electrolytes and other products that exceed the amount tolerated by the body. By performing these functions, the nephrons help in maintaining homeostasis, which is the stable internal environment of the body.

    Rate this question:

  • 3. 

    The Nephrons preform three physiological activities as it produces urine.

    • A.

      Filtration

    • B.

      Reabsorpton

    • C.

      Secretion

    • D.

      Elimination

    • E.

      Storage

    Correct Answer(s)
    A. Filtration
    B. Reabsorpton
    C. Secretion
    Explanation
    The nephrons in the kidneys perform three physiological activities in the production of urine: filtration, reabsorption, and secretion. Filtration involves the removal of waste products, toxins, and excess substances from the blood. Reabsorption is the process of reclaiming useful substances such as water, glucose, and ions from the filtrate back into the bloodstream. Secretion involves the addition of substances, such as hydrogen ions and certain drugs, into the filtrate. These three processes work together to produce urine, which is eventually eliminated from the body. Storage of urine is not a physiological activity of the nephrons.

    Rate this question:

  • 4. 

    This occurs in the renal corpuscle, where water, electrolytes, sugar, amino acids, and other small molecules are forced from the blood in the glomerulus into Bowman capsule as a result of increased pressure.

    • A.

      Reabsorption

    • B.

      Filtration

    • C.

      Secretion

    Correct Answer
    B. Filtration
    Explanation
    Filtration is the correct answer because it accurately describes the process that occurs in the renal corpuscle. In this process, blood is forced from the glomerulus into the Bowman capsule due to increased pressure. This allows water, electrolytes, sugar, amino acids, and other small molecules to be filtered out of the blood and into the Bowman capsule.

    Rate this question:

  • 5. 

    The fluid that is filtrated through the nephrons is called?

    • A.

      Urine

    • B.

      Filtrate

    • C.

      Plasma

    Correct Answer
    B. Filtrate
    Explanation
    The fluid that is filtrated through the nephrons is called filtrate. This term refers to the fluid that passes through the glomerular filtration barrier in the kidneys, containing water, ions, glucose, amino acids, and waste products. It is the initial product of filtration before further processing occurs in the renal tubules to form urine.

    Rate this question:

  • 6. 

    ________ begins as filtrate passes through the four sections of the tubule. The Tubule reclaims needed substances from the filtrate and returns them to the body for reuses. Water, electrolytes and amino acids are returned to the peritubular capillaries, thus re-entering the circulating blood.

    • A.

      Reabsorption

    • B.

      Filtration

    • C.

      Secretion

    Correct Answer
    A. Reabsorption
    Explanation
    The process described in the passage is reabsorption. Reabsorption occurs in the tubule where needed substances such as water, electrolytes, and amino acids are reclaimed from the filtrate and returned to the body for reuse. This process helps maintain the balance of these substances in the body and prevents their loss through urine.

    Rate this question:

  • 7. 

    ____ occurs when substances in the capillaries surrounding the distal and collection tubule secrete ammonia, uric acid, and other substances directly into the tubule, a process that resembles reabsorption, but in the opposite direction. This fluid is now called urine.

    • A.

      Reabsorption

    • B.

      Filtration

    • C.

      Secretion

    Correct Answer
    C. Secretion
    Explanation
    Secretion occurs when substances in the capillaries surrounding the distal and collection tubule secrete ammonia, uric acid, and other substances directly into the tubule, a process that resembles reabsorption, but in the opposite direction. This fluid is now called urine.

    Correct Answer(s)
    A. Produce , maintain and transport sperm
    B. Produce male hormone (testosterone)
    C. Testosterone is essentioal to develope sperm and secondary sex characteristics.
    Explanation
    The purpose of the male reproductive system is to produce, maintain, and transport sperm. It also produces the male hormone testosterone, which is essential for the development of sperm and secondary sex characteristics.

    Rate this question:

  • 9. 

    The testies are located?

    • A.

      Under the bladder

    • B.

      Just behind the rectum

    • C.

      In the scrotum (external sac)

    Correct Answer
    C. In the scrotum (external sac)
    Explanation
    The testes are located in the scrotum (external sac). The scrotum is a pouch of skin that hangs outside the body, below the penis. It is responsible for housing and protecting the testes, which are the male reproductive organs. The scrotum helps to regulate the temperature of the testes, keeping them slightly cooler than the rest of the body, which is essential for sperm production.

    Rate this question:

  • 10. 

    Within the  _____, are numerous small tubes that twist and coil to form seminiferous tubules. These tubules produce_____?

    Correct Answer
    testes sperm, testes,sperm, testis sperm
    Explanation
    Within the testes, there are numerous small tubes called seminiferous tubules. These tubules are responsible for producing sperm.

    Rate this question:

  • 11. 

    The testes also secrete testosterone, which develops and maintains secondary sex characteristics.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the testes do secrete testosterone, a hormone that is responsible for the development and maintenance of secondary sex characteristics in males. These characteristics include deepening of the voice, growth of facial and body hair, increased muscle mass, and the development of male reproductive organs. Testosterone also plays a vital role in sperm production and sexual function.

    Rate this question:

  • 12. 

    What structure stores sperm after it leaves the seminiferous tubules?

    • A.

      Testies

    • B.

      Scrotum

    • C.

      Epididymis

    • D.

      Vas deferens

    Correct Answer
    C. Epididymis
    Explanation
    The epididymis is a structure that stores sperm after it leaves the seminiferous tubules. It is a tightly coiled tube located on the back of the testicles. Sperm are transported from the seminiferous tubules to the epididymis, where they mature and become capable of fertilization. The epididymis also helps in the storage and transportation of sperm to the vas deferens during ejaculation. Therefore, the epididymis is the correct answer.

    Rate this question:

  • 13. 

    The vas deferens is a narrow tube that passes through the inguinal canal into the abdominal cavity. It then extends over the top and down the posterior surface of the ______? 

    • A.

      Rectum

    • B.

      Large intestine

    • C.

      Bladder

    • D.

      Kidney

    Correct Answer
    C. Bladder
    Explanation
    The vas deferens is a narrow tube that carries sperm from the testes to the urethra. It passes through the inguinal canal, which is located in the lower abdomen. From there, it extends over the top and down the posterior surface of the bladder. This pathway allows the sperm to eventually reach the urethra and be ejaculated during sexual intercourse. The other options, such as the rectum, large intestine, and kidney, are not directly involved in the pathway of the vas deferens.

    Rate this question:

  • 14. 

    The union of the vas deferens with the duct from the seminal vesical forms the _____?

    • A.

      Ejaculatory duct

    • B.

      Ejaclatory vesicle

    • C.

      Prostate gland

    • D.

      Cowper gland

    Correct Answer
    A. Ejaculatory duct
    Explanation
    The union of the vas deferens with the duct from the seminal vesicle forms the ejaculatory duct. This duct plays a crucial role in the male reproductive system by transporting sperm from the vas deferens and seminal vesicle to the urethra during ejaculation. It is responsible for the release of semen into the urethra, allowing it to be expelled from the body during sexual intercourse.

    Rate this question:

  • 15. 

    The seminal vesicle contains nutrients that support sperm viability and secretes approximately ____% of seminal fluid that is ejaculated during intercourse.

    • A.

      20

    • B.

      40

    • C.

      60

    • D.

      80

    Correct Answer
    C. 60
    Explanation
    The seminal vesicle is responsible for providing nutrients to support the viability of sperm. It also secretes a significant portion of the seminal fluid that is ejaculated during intercourse. Therefore, it can be inferred that approximately 60% of the seminal fluid is secreted by the seminal vesicle.

    Rate this question:

  • 16. 

    The _______ gland is a triple -lobes organ fused at the base of the bladder.it secretes a thin alkaline substance that accounts for 30% of seminal fluid.

    • A.

      Testes

    • B.

      Vas deferens

    • C.

      Prostate

    • D.

      Cowper

    Correct Answer
    C. Prostate
    Explanation
    The prostate gland is a triple-lobes organ fused at the base of the bladder. It secretes a thin alkaline substance that accounts for 30% of seminal fluid.

    Rate this question:

  • 17. 

    The  ______ glands are located below the prostate and are connected by a small duct to the urethra,.They are pea-shaped glands that also provide alkaline fluid necessary for sperm viability.

    • A.

      Cowper or bulbourethral

    • B.

      Prostate

    • C.

      Urethra

    • D.

      Glans penis

    Correct Answer
    A. Cowper or bulbourethral
    Explanation
    The Cowper or bulbourethral glands are located below the prostate and are connected by a small duct to the urethra. These pea-shaped glands produce and secrete a clear, alkaline fluid that helps to neutralize the acidity of the urethra and provide lubrication during sexual arousal. This fluid also helps to enhance sperm viability by protecting the sperm from the acidic environment of the urethra and vaginal canal.

    Rate this question:

  • 18. 

    The cylindrical male organ composed of erectile tissue.

    • A.

      Urethra

    • B.

      Forskin

    • C.

      Penis

    • D.

      Prepuce

    Correct Answer
    C. Penis
    Explanation
    The correct answer is "penis." The question is asking for the cylindrical male organ composed of erectile tissue. The penis fits this description as it is a cylindrical organ that contains erectile tissue, allowing it to become erect during sexual arousal. The other options mentioned, such as the urethra, foreskin, and prepuce, are all parts or structures associated with the penis but do not fully encompass the entire organ itself.

    Rate this question:

  • 19. 

    The penis encloses the urethra. The urethra expels both semen and urine from the body.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the penis indeed encloses the urethra. The urethra is a tube that runs through the penis and is responsible for expelling both semen and urine from the body.

    Rate this question:

  • 20. 

    The urethra mixes urine and semen when expelled from the body. The urine provides the fluid for semen to travel in.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because the urethra does not mix urine and semen when expelled from the body. The urethra has two separate functions - one for the passage of urine and the other for the passage of semen. These functions are separate and do not occur simultaneously.
