Male RPS

• 2 Main functions of Male Reproductive System

  1. Produce male gametes (sperm cell).
  2. Introduce male gametes to female reproductive system.
• External parts of Male Reproductive System

  Penis and Scrotum
• Penis

  Used for sexual reproduction and urination
• Glans Penis

  is partially covered when uncircumcised.
• Shaft

  Long/short cylindrical part of the penis
• It comprised of erectile tissue

  Shaft
• A pair of loose and pouch-like that contains testes.

  Scrotum
• The passageway of both urine and semen

  Urethra
• Male primary sex organ

  Testes/Testis
• A narrow tube that stores sperm cells

  Epididymis
• This is where immature cells get matured.

  Epididymis
• Carries the sperm cell to urethra

  Vas Deferens
• Sperm cell + fluids

  Semen
• Glands

  Seminal Vesicles

  Prostate Gland

  Bulbourethral Gland (Cowper's Gland)
• Semen

  Sperm Cell + Fluids
• It acts as a climate control system for the testes.

  Scrotum
• Urethra

  Passageway of bot urine and semen
• Scrotum

  A pair of loose and pouch-like that contains testes
• Responsible for making testosterone

  Testes/Testis
• Responsible for producing sperm cell

  Testes/Testis
• Secrete fluids that make up most of the semen

  Seminal Vesicles
• Secretes fluids that nourishes and help the sperm cell to swim

  Prostate Gland
• Secretes a thick and clear mucus to lubricates and neutralizes the semen.

  Bulbourethral Glands
• It reaches its full size after puberty

  Penis
• Where sperm cells and testosterone are produced

  Testes
• Site of spermatogenes

  Seminiferous Tubules
• Where the output of a system amplifies the system (positive feedback) or inhibits the system (negative feedback) 


  Feedback Loops
• These are important because they allow living organisms to maintain homeostasis


  Feedback loops
• State of balance 


  Homeostasis
• 3 main components of Homeostasis

  Receptor

  Control Center and

  Effector
• A feedback mechanism resulting in the amplification or growth of the output signal


  Positive Feedback Loops
• Less common, but occur in specific situations


  Positive Feedback Loops
• Breakdown the homeostasis of the system


  Positive Feedback Loops
• Ex. Blood Clotting, Childbirth, Fruit Ripening


  Positive Feedback Loops
• A feedback mechanism resulting in the inhibition or slowing down of a process


  Negative Feedback Loops
• Always maintain the conditions of homeostasis 


  Negative Feedback Loops
• Occur more in the body, helping in maintaining various conditions of the body


  Negative Feedback Loops
• Ex. Regulation of body temperature, blood pressure and fluid content

  Negative Feedback Loops
