recieves seminal secretions from testes and accessory glands.
drans execretory products from urinary bladder
seminal vesicles
secrete alkaline fluids that aid in neutralizing vaginal acidity and contain nutrients to promote sperm motility and viability and hormones to stimulate uterine contraction
bulbourethral glands
produce alkaline secretions that assist in lubrication and also aid in neutralization of vaginal acidity
preputial gland
secretes alkaline fluid to neutralize acidity of the vagina and provide lubrication
penis
deposits semen in female reproductive tract. expels urine from body
ovary
produces eggs
oviducts
recieves egg at ovulation
site of fertilizatrion
uterine horns
site of implantation and embryonic development
urethra
drains execretory products from urinary bladder
vagina
reieves penis during copulation
serves as part of birth canal
urogenital sinus
common champer formed by junction of the urethra and the vagina that drains urine from the body and serves as part of the reproductive canal during copulation and birth
papilla
develops into the clitoris
ductus arteriousus
short connection joining the pulmonary trunk with the aorta and allowing a portion of the blood from the pulmonary trunk to enter the aorta instead of flowing to the ungs
foramen ovale
re-routes blood to bypass the lungs
doudenum
recieves chyme from the stomach along with bile and digestive enzymes from the gallbladder and pancreas
chromosomes
consist of DNA and associated small particles known as histones
Genes lpcated at specific locations along the chromosome
Centromeres that serve as the points of attachment for 2 identical hromatids of each replicated chromosome
homologous chromosome
a chromosome that contains the same genes at the same location along the chromosomes
somatic cells
body cells such as skin and muscle cells
diploid
A cell or an organism consisting of two sets of chromosomes: usually, one set from the mother and another set from the father. In a diploid state the haploid number is doubled, thus, this condition is also known as 2n.
Germ cells
reproductive cells, including sec cells such as ova and sperm and spores.
contain only one member of each homologous chromosome pair, contain 23 chromosomes
Kinetochores along the centromere region of the chromosome.
haploid
cells having just one member of each chromosome pair
prophase
nuclear envelope dissolves
duplicaated chromosomes consense
kinetochores attach to the microtubules
metaphase
sister chromatids linr up in the center of the cells, along the metaphase plate
anaphase
sister chromatids start to separate from one another
telophase
nuclear envelopes srat to form around each group of seperated chromatids
