BIOL 129 Study Guide - Midterm Guide: Vas Deferens, Inguinal Hernia, Inguinal Canal
Document Summary
Scrotum: the sac that holds the testis, the inside of the scrotum connects to the abdominal cavity through the inguinal canal. An inguinal hernia is when the intestines push through the inguinal canal and enter the scrotum. Epididymis: series of hollow tubes that store mature sperm cells. Ductus (vas) deferens: when a male ejaculates (a series of peristaltic contractions of smooth muscle), sperm cells travel from the epididymis, through the ductus deferens, and into the urethra. In the ductus deferens, the sperm cells are suspended in a salt water solution (extracellular fluid) The sperm and fluid make up about 10% of the ejaculated semen. Seminal vesicle: gland that secretes a sticky yellowish/whitish fluid. Urethra: tube that transfers urine from the bladder to the outside of the body and transports sperm and semen from the reproductive organs to the outside of the body.
