Constructed Response

1.    A = urinary bladder
       B = urethra
       C= penis
       D= vas deferens
       E= testes
       F = scrotum
       G= ovary
       H= oviduct
       I= uterus
       J= urinary bladder
       K = vagina

2.   Urinary bladder serves to temporarily store urine.
      The urethra transports semen and urine from the body.
      The penis is an adaptation for internal fertilization.
      The vas deferens carries sperm away from the testes.
      The testes makes sperm and testosterone.
      The scrotum is a pouch housing the testes which keeps them 2 C -4 C degrees
      cooler than the body.
      The ovary produces eggs and estrogen.
      The oviduct or fallopian tube carries the egg from the ovary and is the site of internal
      fertilization and initial cleavage in humans.
      The uterus is where development of the embryo/fetus is completed.
      The urinary bladder serves to temporarily store urine.
      The vagina or birth canal is where the baby is born and where sperm are initially
      deposited in the female.

3.   Gametogenesis is the production of gametes.   This occurs in the ovaries in females and in the
testes in males.   The zygote is the diploid structure formed in the oviduct by the union of egg and sperm. This process is called fertilization.   Cleavage refers to the initial mitotic cell divisions of the zygote.   The hollow ball structure composed of a single cell layer eventually formed from these cleavages is called the blastula.  This blastula continues to develop and indents to form a two and
then a three cell layered gastrula.   This gastrula develops into specific structures in the embryo in a
process called differentiation.

(Other explanations of this process may be acceptable.)

4.  The follicle stage involves the final maturation of the egg in a pouch in the ovary called a
follicle.   Ovulation is the release of this egg.   The yellow tissue which forms in this follicle
once the egg is released is referred to as being the corpus luteum stage.   When the uterine
lining is sloughed off and released, the final stage of the menstrual cycle called menstruation
occurs.

FSH (follicle stimulating hormone) produced by the pituitary stimulates the final maturation of
the egg in the follicle.  LH (luteinizing hormone) is also produced by the pituitary gland.  It
stimulates the development of the corpus luteum or yellow tissue in the empty ovarian follicle
once the egg is released.   The hormone estrogen produced by the ovaries initiates the thickening
of the uterine lining and stimulates the development of female secondary sex characteristics.
The corpus luteum produces the hormone progesterone which maintains the thickness of the
uterine lining which estrogen has already begun.
