Levels of Organization Within an Organism
  • Cells Building block of both unicellular and
    multicellular organisms.
  • Tissues- A group of cells functioning together to
    perform an activity.
  • Organs- Groups of two or more tissues that
    function together.
  • Organ Systems- Cooperation among organs makes
    life function within an organism efficient.

Male Organs of Reproduction and Their Functions
  • The testicles The testicles produce the sperm
    cells that fertilize the females egg. The sperm
    are produced in the seminiferous tubules within
    the testicles. Testosterone is produced here.
    Testosterone is the hormone that makes the
    appearance and behavior of a male masculine.
  • The epididymis This is where the sperm are
    stored from the testicle to mature.
  • The scrotum The scrotum is a sac that contains
    and protects the testicles. It regulates the
    temperature to be a few degrees lower than body
    temperature since sperm like this lower
    temperature.
  • The vas deferens The vas deferens transports
    the sperm from the epididymis to the urethra.
  • The urethra A large muscular canal extending
    from the urinary bladder. This is the pathway
    through with urine and semen are excreted.
  • Accessory sex glands The seminal vesicles,
    prostate, and bulbourethral glands are a part of
    this category. They primarily add to the semen
    fluid to provide health and nutrition to the
    sperm.
  • The penis The organ of copulation. It is
    characterized by its spongy, erectile tissue. It
    provides the passage way for urine and semen.

Differences in the Poultry Male Reproductive
Organs
  • The testes are contained in the body cavity.
  • Each vas deferens opens into small papillae,
    which are located in the cloacal wall.
  • Male fowl have no penis but have a copulatory
    organ.
