Science

• Reproductive System

  ￫ Is responsible for the process of reproduction, or the creation of offspring of the same species. Main function is to reproduce.
• Functions of the MRS

  ￫ Produce sperm, Secrete male hormones (Testosterone), Deliver the sperm into the site of the fertilization
• Spermatogenesis

  ￫ The process of producing the sperm.
• Adolescence

  ￫ Capable to reproduce
• Penis

  ￫ A hollow tube that contains the urethra. Used for intercourse and urination.
• Scrotum

  ￫ A bag or pouch-like part that holds the testes.
• Testes (Testis = Singular)

  ￫ The gonads that produce gametes and testosterone it is responsible for production of sperm.
• Seminiferous Tubules

  ￫ Where the production of sperm and spermatogenesis occurs.

  ￫ Produces 1500 sperm cells every second.
• Head

  ￫ Encloses the nucleus, which carries the male’s genetic material.
• Middle piece

  ￫ Contains the mitochondria that provides energy for the sperm to move.
• Tail

  ￫ Used by the sperm cell for movement.
• Epididymis

  ￫ A comma-shaped part of the MRS where the newly formed sperms are conveyed from the Testes.

  ￫ This is where the sperm matures and are stored.

  ￫ It takes 14 days for the sperm to mature.

  ￫ It takes 2-4 days before the sperm gets released.
• Vas Deferens

  ￫ it is a long transport tube that carries the sperm from the epididymis to the ejaculatory duct.

  ￫ Also known as ductus deferens.
• Ejaculatory Duct

  ￫ Formed by the vas deferens and the seminal vesicle; carries the sperm to the urethra.

  ￫Pathway of sperm to urethra.
• Urethra

  ￫The passageway of both urine and semen.
• Seminal Vesicles

  ￫ Secretes an alkaline fluid that contains sugar, which provides energy to the sperm cell.
• Prostate Gland

  ￫ Releases a milky fluid that liquefies the semen, making the sperm move faster.

  ￫ It makes up 25% of the semen.
