|what do testes produce?||They produce sperm cells and male sex hormones testosterone|
|How much sperm can the testes produce?||The testes can produce as many as 12 trillion sperm in a male's lifetime, and about 400 million in a single ejaculation|
|where are testes located?||They are located in a hollow sac of the scrotum|
|How long in diameter is each testes?||About 1.5 to 2 inches long along its axis and around 1 inch in diameter|
|How are testes connected to the ventral body cavity?||Testes are connected to the vital organs of the ventral body cavity through the spermatic cords|
|what does the spermatic cord transport?||Nerves, blood vessels, and lymphatic vessels travel through the spermatic cords to support the testes|
|what wraps around the testes?||The testes are wrapped by the tunica vaginalis, an extension of the peritoneum of the abdomen, and the tunica albuginea, a tough, protective sheath of dense irregular connective tissue.|
|The testes are divided into segments called?||Lobules. Each of the Lobules contains several tightly coiled tubes called seminiferous tubules|
|what divides testes into segments?||Testes are divided into segments by invaginations of the tunica albuginea|
|what does the walls of the seminiferous tubules contain?||They contain the germ cells, Sertoli cells, and Leydig cells that give the testes their function|
|The germ cell in the walls of the seminiferous tubules differentiate to produce?||Spermatocytes|
|what do Spermatocytes develop into?||Spermatides and eventually into spermatozoa or sperm cells|
|what is the function of sertoli cells?||They support and protect the immature cells as they travel through the seminiferous tubules and slowly mature|
|what is the function of the Leydig cells?||They produce the male hormone testosterone that produces the secondary sex characteristics associated with males.|
|How long does it take each sperm to mature?||It takes each sperm cell 72 days to mature|
|what is the function of the scrotum?||It helps keep the testes and sperm at the correct temperature|
|why does the scrotum lie outside the body?||Spermatogenesis requires a temperature that is three to five degrees Fahrenheit below body temperature. This makes it being outside the body an optimal place to be|
