How does the fetal pig structure compare with the male human structure?
In comparison to a human uterus, the pig uterus is greatly diminished in size, and acts as part of the birth canal rather than housing the developing fetuses. It is formed by the joining of the two uterine horns at the midline of the body.
Where are the gonads located in the fetal pig?
Male reproductive organs: The location of the male gonads, the testes, in a mammal depends on the animal’s age. In young pigs, the testes are in the lower abdomen posterior to the kidneys. As the pig matures, the testes drop into the scrotal sacs, which are ventral to the anus.
How are fetal pigs and humans different?
Uterus – The fetal pig uterus is of a type called bicornate, compared to the simplex human uterus. This means that the pig uterus has two large horns in addition to the body. These horns are sometimes confused with the much smaller Fallopian tubes.
How is the pig anatomy similar to the human?
Pigs share a number of surprising comparable traits with humans. For instance, we both have hairless skin, a thick layer of subcutaneous fat, light-colored eyes, protruding noses and heavy eyelashes. Pig skin tissues and heart valves can be used in medicine because of their compatibility with the human body.
What is the difference between male and female pigs?

Where are the testes located in a fetal pig?
scrotal sacs
The testes are housed in the scrotal sacs which are located in the posterior pelvic cavity. The testes are the site of sperm production and maturation. Lying directly on top of the testes is the coiled epididymis where mature sperm is stored prior to ejaculation.
What structure can be found in both the male and female urogenital systems?
So here we can see that kidney, ureter, urinary bladder and urethra. These four structures are common in male and females.
How can you tell if a fetal pig is male or female?
Examine the fetal pig and locate the external features shown above. o Female: The urogenital opening in the female is immediately ventral to the anus and has a small genital papilla marking its location. o Male: The scrotal sac is ventral to the anus and a urogenital opening is just posterior to the umbilical cord.
Where are the testes located in the male pig?
Do male pigs have uterine horns?
Ovaries are the site of oocyte production and maturation. In pigs, each ovary is attached to a highly coiled uterine horn (similar to a human’s fallopian tubes). Unlike human fetuses which develop in the uterus, pig fetuses develop in the uterine horns.
Which female reproductive structures are different when comparing humans and pigs?
Comparison of the gross anatomy and epithelium in the genital tract in women and pigs. The porcine uterus differs macroscopically from the human simplex uterus by having bilateral horns (bicornuate) [23]. The porcine cervix displays a characteristic feature, not found in women; the cervical pulvini (red arrow) [23].

Where are the testes in a fetal pig?
What is the reproductive system of a pig?

What are male testes?
Listen to pronunciation. (TES-tis) One of two egg-shaped glands inside the scrotum that produce sperm and male hormones. Also called testicle.
How are male and female reproductive systems functionally different?
The male reproductive system produces male gametes while the female reproductive system produces female gametes. Male gametes and female gametes unite during the sexual reproduction and form a diploid cell called zygote. This is the key difference between male and female reproductive system.
What are the similarities of male and female reproductive system?
Comparing Male and Female Reproductive Systems Both systems have gonads that produce (sperm and egg or ovum) and sex organs. And both systems experience maturation of their reproductive organs, which become functional during puberty as a result of the gonads secreting sex hormones. Table 3.
