A species makes offspring
Reproductive System
In the testes, the exocrine gland produces (1), and the endocrine gland produces (2).
1. sperm
2. testosterone
Sperm travels via?
Seminiferous tubules-->Epididymus-->Vas deferens-->Ejaculatory duct-->Urethra-->Penis
The sac of the reproductive system?
Scrotum
The Scrotum (____)
Lowers temperature for sperm production.
Sperm develop in the?
Seminiferous tubules
What nurses sperm?
Sertoli cells
in between ST, produce testosterone?
Interstitial cells
Interstitial cells are in between ST, and they produce (____).
Testosterone
Male urethra parts?
Prostatic (prostate)
Membranous (diaphragm)
Spongy (penis)
What are the male accessory glands?
Seminal vessicles (nourish sperm)
Prostate (milky, activate sperm)
Bulbourethral gland (clear, basic, protect sperm)
male accessory gland that nourishes sperm?
Seminal vesicles
male accessory gland that is milky, and activates sperm?
Prostate
male accessory gland that is clear, basic, and protects sperm?
Bulbourethral gland
In the ovaries the exocrine gland produces (1), and the endocrine gland produces (2).
1. eggs
2. estrogen and progesterone (into blood)
The egg travels via?
Ovary-->Fallopian tube-->Uterus-->Cervix-->Vagina
The fallopian tube is for egg?
fertilization
The uterus in for egg?
implantation
fertilized egg
zygote
An egg is penetrated by sperm. They form a single nucleus.
fertilization
3 days. Solid ball of cells.
Morula
hollow ball. 1 week implants into the Uterus.
Blastula
3 germ layers. 2 weeks. Implantation is complete.
Gastrula
9 weeks. Growth, tissue and organ specialization.
Fetus
uterus wall closest to base
Decidua basalis
region of the uterus wall surrounding the rest of the blastocyst.
Decidua capsularis
chorionic villi and uterus tissue. All nutrient exchange here.
Placenta
encloses fluid sac (amniotic cavity).
Amnion
If pregnant what secretes HCG?
blastocyst
=inheriting traits.
Genetics
(before fertilization)- a cell (an egg) has 23
chromosomes. n
Haploid
(after fertilization)- a cell has 46 chromosomes. 2n
diploid
2 different copies of the same chromosome (one from mom and one from dad)
homologous chromosomes
there are genes on all chromosomes. In regards to homologous chromosomes (the copies), we now have 2 copies of each gene (one copy on each chromosome), called?
alleles
once the follicle releasses the developing egg, the follicle is then called a?
corpus luteum
what does the implanted blastocyst release during embryonic development?
HCG (stimulates follicle)
maternal arteries and veins exchange with fetal chronic villi together making up the?
Placenta
leads to Umbilical Cord
allantois
first blood/germ cells
yolk sac
form skin and NS
ectoderm
forms internal organs
mesoderm
forms dig. and resp. tracts and glands
endoderm
during embryonic development, where does the blastula implant?
endometrium - decidua basalis/d. capsularis
forms embryonic membranes
ICM
only forms chorion
trophoblasts
what secretes enzymes to allow implantation?
trophoblasts during the blastula stage.
what stimulates the ovary?
LH and FSH
what does the ovarian follicle secrete?
estrogen and progesterone
what does estrogen do in the ovarian follicle?
thickens uterine lining
what does progesterone do in the ovarian follicle?
inhibits other follicle growth
