Thysiology of Female Lep System The & rep system include diff parts. like elferine tube or Oviduct, cetereus. wix of uterus , rapina & vulva uterine tubes :- The e. tubes ore Oviduct tube extendedd They provide root on fallopian from etterus. for entry of sperm to reach ovum & treanmport the る。 cocyte & fertilised ora to reach into etcнии. The funnel-shaped structure present in each fallopian tube is called the infundibulum, which attaches to a finger-like projection called fimbriae. The widest part of the fallopian tube is called the Ampulla, and the portion that joints the ampulla to the fallopian tube, the term tabe, is called the Isthmus.
