Mammalian Reproduction System🐾 Flashcards
What are the three layers that consists within the uterus?
- Perimetrium
- Myometrium
- Endometrium
What consists within the male reproductive system?
- Testes (where sperm is produced)
- Epididymis (where sperm mature and stored)
- Vas Deferens (tubes that carry sperm away from testes)
- Urethra (tubes that carry sperm/urine/semen out of body)
- Penis (semen and urine can pass through)
- Prostate gland (secretes fructose and enzymes to sperm which forms semen)
- Bulbus glandis (Erectile tissue)
What consists within the female reproductive system?
- Cervix- (protecting the tract from infection)
- Vagina- (produces acidic mucus to kill bacteria to fight infection)
- Oviducts- (where fertilisation occurs)
- Ovaries- (produces ova/oestrogen/progesterone)
- Vulva- (swells during oestrous)
- Uterus- (stretching to fit growing foetus)
- Uterine horn- (can allow for the development of several offspring at once)
What are the functions of female reproductive tract?
- Lactation- produce milk
- Birth- Expulsion of foetus
- Nourishment- housing and nourishment for fertilisation and embryo
- Ova- production of ova
What is Placenta?
- Temporary organ attached to uterus, develops with foetus
- Occurs when pregnancy is established
- Provide connection between foetus and maternal tissue to provide nutrition, respiration, protection and excretion
- Contains both foetal (from umbilical cord (from uterine wall) blood vessels
What is the uterus like in certain types of mammals?
- Duplex (Rabbit)
• two uterine horns
• two cervices
• one vagina - Bicornuate (pig,cat and dog)
• two long uterine horns
• common uterine body
• one cervix - Bipartite (cow)
• small uterine horn
What is the function of the testes? - Male
- Where sperm is produced
What is the function of the Epididymis? -Male
- Where sperm is matured and stored
What is the function of the Vas Deferens?- Male
- Tubes that carry sperm away from the testes
What is the function of the urethra? -Male
- Tubes that carry sperm, urine and semen out of the body
What is the function of the penis? -Male
- Located on the outside of the body, semen and urine can pass through; containing three columns of erectile tissue
What is the function of the prostate gland?- Male
- Adds secretions (fructose and enzymes) to the sperm to form semen
What is the function of the bulbus glandis? -Male
- Erectile tissue that swells up during copulation to lock the male to the female
What happens during Copus Cavernosum
- Penis fills with blood
What happens during Copus spongiosum?
- Prevents the collapse of the urethra during erection
What is the function of the cervix? -Female
- A muscular barrier sealing the uterus; maintaining a sterile environment and protecting the tract from infection
What is the function of the vagina? -Female
- Shaped to fit the penis during mating and produces acidic mucus to kill bacteria and prevent infection
What is the function of oviducts? -Female
- Known as a Fallopian tube; where fertilisation occurs
What is the function of ovaries? -Female
- Where ova are produced as well as oestrogen and progesterone
What is the function of the vulva? -Female
- External part of the tract; can swell during oestrous to show receptivity to the male (ready to mate)
