The corpus spongiosum, and two corpus cavernosa.
What are the four components of semen?
secretions from the seminal vesicles, prostate gland, bulbourethral gland and sperm cells.

What are the ovaries?
these are oblong 3-4cm organs that produce oocytes.
What is the stroma? (Female)
This is the background substance in the ovaries.
What are the fallopian (uterine) tubes?
The oocytes move to these from the ovaries during ovulation/
What are the fallopian (uterine) tubes?
The oocytes move to these from the ovaries during ovulation.
What is the gamete-producing organ of the female reproduction system?
The ovaries.
What are the structures of the vulva?

What are the three layers of uterus from superficial to deep?
perimetrium
myometrium
endometrium

What is the hormone detected in pregnancy identification?
HCG (human chorionic gonadotropin)
What are the changes in hormone levels during menstruation?
This is the loss of the endometrial layer of a womans uterus after the levels of estrogen and progesterone drop during the menstrual cycle.
What is the process of ovulation and the change in hormone levels?
d
What is the process of ovulation and the change in hormone levels?
This is the process of a mature egg traveling from the ovary down the fallopian tubes to the uterus for a chance to be fertilized
.FSH stimulates the maturation of eggs in follicles. one will, and will release a mature egg. The maturing follicles release estrogen, and the increase in estrogen will cause increase in levels of lutenizing hormones (LH), this causes the egg to burst through the ovary.

What is the process of a vasectomy?
An incision is made on each side of the scrotum and both vas or ductus deferens are cut, all the free ends are tied which prevents the travel of sperm from the testes to the spermatic cords.
What is the function of FSH?
This stimulates the follicles to mature into oocytes.
What is the function of HCG?
This hormone tells the corpus luteum to keep producing progesterone, which keeps the lining of the uterus thick for a healthy pregnancy. until the placenta takes over at 10 weeks producing progesterone.
What is the function of HCG?
This hormone tells the corpus luteum to keep producing progesterone, which keeps the lining of the uterus thick for a healthy pregnancy. until the placenta takes over at 10 weeks producing progesterone.
What is the function of Lutenizing hormone?
lutenizing hormone triggers ovulation and the development of the corpus luteum.
What is the function of progesterone?
Progesterone promotes the thickening of the lining of the uterus.
What is the process of tubual ligation?
This is where the fallopian tubes are burned clipped cut or tied.

ovary
fallopian tube
uterus

What is an allele?
One of several different forms of a gene that is present on a specific location on a specific chromosome.
What is a blood type allele?
These are the different alleles that correspond with each blood type. 4 phenotypes and 3 genotypes that pair to make each phenotype.
What is a blood type allele?

How does a punnett square work?
This is the determining of dominant of recessive traits from the mother and father.
What is heterzygous?
There are two different alleles for one trait.
What is homozygous?
There is only one type of allele for a specific trait.
What is phenotype?
The observable characteristics that result from the interactions of the genotype.
What is genotype?
The set of alleles responsible for a particular trait.
What is a karyotype?
This is a visual of all the chromosomes in an individual.
What is a gamete?
These are the sperm and egg cells that each have half the chromosomes of our bodies. reproductive cell.

When there is half the full contingency of chromosome. (23) n
What is diploid?
When there is the full contingency of chromosomes. (46) 2n
What are autosomal chromosomes?
These are all chromosomes not related to the sex of the organism. (44)
What are sex linked traits?
This the 23rd chromosome of each the mother and father that help determine the sex of the offspring. MOM IS ALWAYS X, DAD CAN BE X OR Y. XY = male XX= female
Describe the human genome project?
This is a project that has a goal of determining the sequence of chemical base pairs on DNA, and being able to map the genes of a genome from a physical and functional standpoint.
What is a genome?
This is the complete set of genes in a cell or organism.
