Reproductive System Anatomy

Male Reproductive System

• The male reproductive system consists of:
  • Testes: produce sperm
  • Epididymis: stores and transports sperm
  • Vas deferens: muscular tube that transports sperm
  • Ejaculatory ducts: connect vas deferens to urethra
  • Urethra: tube that carries sperm and urine out of the body
  • Penis: male genital organ
  • Scrotum: sac of skin and muscle that protects testes

Female Reproductive System

• The female reproductive system consists of:
  • Ovaries: produce eggs
  • Fallopian tubes: connect ovaries to uterus
  • Uterus: muscular organ that supports fetal development
  • Cervix: lower part of uterus that opens into vagina
  • Vagina: muscular tube that connects cervix to outside of body
  • Vulva: external female genital area

Anatomy of Penis

• The penis consists of:
  • Root: attaches to abdomen
  • Shaft: long, thin part of penis
  • Glans: sensitive tip of penis
  • Foreskin: layer of skin that covers glans
  • Urethra: tube that carries sperm and urine out of body
  • Corpus cavernosum: two cylindrical bodies of erectile tissue
  • Corpus spongiosum: single cylindrical body of erectile tissue surrounding urethra

Anatomy of Vagina

• The vagina consists of:
  • Introitus: opening of vagina
  • Vaginal canal: muscular tube that connects cervix to outside of body
  • Fornix: upper part of vaginal canal
  • Vulva: external female genital area
  • Hymen: thin membrane that partially covers introitus
  • G-spot: area of sensitive tissue on front wall of vagina
  • Bartholin's glands: produce mucus to lubricate vagina

Urogenital System

• The urogenital system is a combination of the urinary and reproductive systems
• Shared structures:
  • Urethra: carries both urine and reproductive cells
  • Perineum: area between anus and genitals
  • Pelvic floor muscles: support both urinary and reproductive organs
• The urogenital system is responsible for:
  • Urination
  • Reproduction
  • Sexual function
