I.
Anatomy of Reproductive Tracts
A. Female





_______________: Primary reproductive organ
-
meiosis takes place
-
fertile eggs develop
_______________: Developing egg that has not yet been released
-
produce _____________________
-
mature follicle is ________________ and the egg is released
-
release of egg causes estrogen levels to ______________
__________________ ____________________ (CH)
-
____________________________
-
where follicle was released
Corpus ___________________(CL)
-
Yellow body
-
produces progesterone = _____________________
-
prevents new ______________development
Estrous cycle
-
____________________: when follicle is developing
-
____________________: when egg is released
* when female is receptive to the male
* “standing heat”
-
____________________: CL is actively producing progesterone
*if pregnant = CL remains active
-
____________________: CL recedes and a new follicle begins to
develop


Infundibulum
-
___________________________
-
where egg is released into
-
moves egg to oviduct
Oviduct
-

where _____________________ takes place
Uterus

________________

Attaches and develops until birth
__________________________


Path from ______________ to the outside of the animal

Sperm ____________________ here in some species

Seals off during ______________________
Vagina

Site on ________________________ in some species

B.
Visible part of the female reproductive tract
Male

_______________


____________________ ______________________




Surround seminiferous tubules

Produce ____________________
Rete testis
Where _____________________ sperm collect
__________________ ducts


Meiosis takes place here
_____________ cells


Primary male reproductive organ
Bigger storage area
Epididymis

Final sperm ___________________ site

3 parts of epididymis
-

During ______________________

Sperm travel from ____________, through vas ____________, to the
________________ and ____________ before being deposited in the
female


II.
Several glands add _______________ to the sperm
________________: sperm cells and fluid
The Reproduction Cycle
A. Fertilization

___________________________


Fluids from female “wash” sperm so make it capable of fertilization
Zona pellucida

_____________________ surrounding egg

Must be ______________________by sperm

Once a sperm has penetrated, no more are allowed to enter


“_______________ _______________”
Zygote

Diploid fertilized egg

Travels remaining distance to the uterus

Becomes an embryo
fetus
B. Pregnacy

__________________ follicle develop

Cervix develops a ___________________________ to keep out bacteria
C. Parturition

Fetus starts to secrete a hormone
prostaglandin

ruptures CL
causes mother to release
end of pregnancy
hormones released by mother

Milk _______________ is controlled by ____________________

Milk formation is controlled by ______________________

