Responsible for producing gametes that fuse together with the opposite sex

Sperm

Male Sex Cells

Egg

Female sex cells

Reproductive system

responsible for the hormones being produced for development

Scrotum

houses the testes in males

Testes

Sperm production is in the ______

retract the testes closer to the body to be warmer

2 degrees Celsius

Temperature is important (needs to be cooler)- Human testes are _____ cooler

Cremasteric Pouches

Testes are enclosed in the ____________ _______

Spermatic Cord

Cranially connected to the testes is the _________ ____

Spermatic Cord

Contains the vas deferens, spermatic artery and vein, nerves, and lymphatic vessels

Epididymis

coiled to the side of each teste

Seminiferous tubules

Sperm production is within the ________ ______ (be specific)

Epididymis

Sperm is stored in the ___________

leave the epididymis, into the vas deferens, and towards the urethra

Sperm ejaculation pathway

Yes

Do both woman and men have a urethra?

Vagina

Sperm are highly alkaline to fight the high acidity of the _______

Bulbourethral Glands and Preputial Gland

The 2 glands that produce the alkaline secretions that keep Sperm basic

Seminal vesicles

secrete a viscous fluid to keep the sperm from drying out

Vas deferens and urethra

Seminal vesicles are located at the junction of what 2 features?

Seminal vesicles

Fluid contains Fructose for energy and hormones to promote sperm motility in the female

Testicle

Epididymis

Sperm pathway/Vas deferens

Bladder

Seminal vesicle

Prostate

Penis

Female Reproductive System

Ovaries are paired, and located caudal to the kidneys

Oviduct

coiled “communications” to each ovary

Oocytes (eggs)

What does the oviduct carry during ovulation?

Oviduct

No physical connection; use “finger-like” projections to sweep eggs into the oviduct

Fertilization

occurs in the upper third of the oviduct

Implantation

occurs further in the Uterus

Nucleus

Egg

Egg leaves ovary and enters fallopian tube

Step 1

Ovary

Sperm enters egg and unites with nucleus

Step 2

Fallopian tube

Fertilized egg divides

Step 3

Uterus

Cells attach to uterus

Step 4

Uterine Horns

In Pigs, the Uterus is divided into ___________ ____, where embryonic development of the fetus occurs

Uterine Body

In pigs, where the Uterine Horns converge on the cervix

Uterine Horns

In humans, the ______ _____ reduced and the zygote implants and develop in the body of the Uterus

Cervix

construction of semi- cartilaginous tissue

Vagina

extends caudally from the Cervix

Urethra

Vagina and Cervix are joined by the _______

Urogenital Sinus

Vagina and Urethra open up to a common chamber called the

Urogenital sinus

• Handles both reproductive and urinary systems

• Opens to the outside of the body through the Urogenital Opening

• Humans will NOT have a single opening, they are separate, but they are in proximity of each other

Fimbriae

Uterine Tube

Fundus

Endometrium

Inside wall

Myometrium

Outside wall

Cervix

Vagina

Ovary

Genital Papilla

On the fetus, the finger-like projection outside the body

Genital Papilla

• Like the male penis

• Sends sensations to the brain

• Covers the Urogenital Opening

Penis

Preputial gland

Bulbourethral gland

Seminal vesicles

Urethra

Vas deferens

Epididymis

Oviduct

Uterine horns

Urethra

Vagina

Urogenital Sinus

Genital pappila

Ovaries

will be swollen due to hormone sinuses. Scars from released eggs can be seen

Infundibulum

Opening of the oviduct that receives eggs from the ovary

Mesosalpinx

Holds the coils of the oviduct and contains the blood vessels for the oviduct tissues

grow in size
