Male Reproductive Anatomy (p.321) Scrotum- it’s the pouch of the pouch of the skin that encloses the testes. Testis- It produces the sperm and sex hormones. seminal vesicles- They contribute nutrients and fluid to semen. Epididymis- They are ducts where sperm mature and some sperm are stored. vas deferens (also called ductus deferens)-they conduct and store sperm. Urethra- conducts sperm bulboourethral gland-they contribute mucus-containing fluid to semen. prostate gland- contributes fluid to semen. Penis- the organ of sexual intercourse.

Sperm production anatomy seminiferous tubules- long, coiled structure contained within chambers of the testis; where sperm are produced. sertoli cells-cell associated with developing germ cells in seminiferous tubule, secretes fluid into seminiferous tubule and mediates hormonal effects on tubule. sperm (head, middle, tail)-mitochondria in the middle piece provide energy for the movement of the tail, which is a flagellum. The head contains a nucleus covered by a cap called the acrosome; male gamete having a haploid number of chromosomes and the ability to fertilize an egg, the female gamete. acrosome-cap at the anterior end of a sperm that partially covers the nucleus and contains enzymes that help the sperm penetrate the egg.

Female Reproductive System Ovary-produces eggs and sex hormones. Fimbria- small bristlelike fiber on the surface of a bacterial cell, which attaches bacteria to a surface. oviducts (also called fallopian tubes, uterine tubes)- conduct eggs; location of fertilization (uterine or fallopian tubes) uterus- houses developing fetus endometirum- lines the uterus participating in the formation of the placenta, which supplies nutrients needed for embryonic and fetal development. Vagina- receives penis during sexual intercourse; serves as birth canal and as an exit for menstrual flow. Cervix- contains opening to uterus Vulva- external genitals of the female that surround the opening of the vagina.
