Document Summary
A system of ducts that are specialized to transport or house the gametes after they are produced. In the abdomen during development and descend into the scrotum during the 7th month of gestation. The organ used to deposit semen into the female. The accessory glands (secrete fluid into the reproductive tract) Each testicle is separated from the other by a septum (protects against the spreading of infection) The temperature of the testis is carefully regulated by moving them closer to or farther away from the body. Two muscles are responsible for this movement: dartos muscle. Smooth muscle below the skin of the scrotum. In a cold environment, the dartos contracts and pulls the entire scrotum toward the body (wrinkled appearance) In the connective tissue between the seminiferous tubules. Takes about 20 days for sperm to reach the tail. Secretes an alkaline fluid that neutralizes the acidity of the vagina. Clear slippery fluid to lubricate the head of the penis.
