Grade 12 Human Reproduction
The          uterus          is also known as the womb.

The           ovaries           produce the egg inside a woman.

The            scrotum             contains the male's testes.

The                  prostate gland                  lies beneath the bladder, and secretes a fluid that gives semen its characteristic odor and texture.

Prenatal development begins with the union of the egg and the sperm, this union is also known as              conception             .

The sex cells are also called           gametes          .

The pattern of cell division that is responsible for transmitting traits from both parents to the developing child is called           meiosis          .

Once the two sex cells combine, that cell now has      46      chromosomes. This new cell is called a          zygote         .

The baby will be a girl if the          father          transmits a                X chromosome               , and the baby will be a boy if a                Y chromosome                is transmitted.

Chromosomes carry         genes         which are key to a person's uniqueness.

The period of the          embryo          is from week 3 to 8. During this period, the cells of the embryo form a root-like structure called a            placenta           , that attaches to the spongy wall of the uterus. The                amniotic sac                is also formed around the baby for protection.

The period of the         fetus         is from week 8 until birth. During the ninth month, the baby moves his/her head down into the birth canal. This process is called              lightening             .

A baby is considered full term between      37      and      42      weeks.
