Physiology of Female Reproductive System

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. Werus combat The uterus serves al the site for emplantation of fertilised evum A der of factus during pregnancy If there is no fertilization on To foctal puauith the uterus involves in the process called mestrual eyele. Cervix of etenus :- → The Secretory colus of cervix produce melosal fened containin neater, Slycoproten, enzyme, Lipid & inorganic salt 7 Both cerevix & Cervical mucous protect the Sperm from phagocyto Vaginai It is a long, fibromuscular cand lined uith mucous leade into the uterine cervix membrane whit The inside of the muscular layer of those cetares consists of the cew Triple layer Outer endomakrium, myomatericum, and fen parimaterian.

The pressure exerted by the fluid deads to reupture of graffian fourcle. At the same time, in the uterus, there is the repair of endomakrium. Because of estrogen, the endomaterial lining thickens to 4-10mm in diameter teamed as the proliferative phase, or preovulatory phase. Orculation:- 14" day of mentrucat the 14 cycle ruptures lof graffian follicle leads to 2 oocyte release of in the form of ora called ovulation.

If fertilization doesn't occer the level of estrogen & preagesterone decline due to depeneration of corpus lenteun. The withdrawl estrogen & progestre reads to menstrevation.
