The Epididymus is the site where the sperm mature and the Vas-derin carries the sperm from the testis to the urethra. The Urethra carries urine and sperm out of the body.

Q:What is internal fertilization and external fertilization?
A: External is where the gametes join outside the body where you need large number of gametes and water. Internal is where the gametes are joined inside the body where you need specialized organs and mating rituals.

Q: What is ectoderm,mesoderm, and endoderm?
A: Edoderm-living of digerstive, roproductive, and repiratory system
Mesoderm- muscles, blood, and the bones

Q: What is Tubal Ligation?
A: getting the fallopian tubes tied to prevent pregnancy

Other things to know for the test:

Endocine system- Regulates bodily function and maintains homeostasis and it signals secrete hormones into the bloodstream

Hormones- chemicals released into the bloodstream (ex. Estrogen)

Pituitary glad- secretes nine hormones and regulates other endocrine glands
