Fallopian Tube
The function of the Fallopian tube or oviduct is to convey the ovum from the ovary to the uterus by peristalsis .
Fertilisation of the ovum generally takes place in the upper portion of the Fallopian tube ( ampulla ) .
Each Fallopian tube ( 10-20 cm ) consists of four parts : ( i ) Infundibulum : Funnel shaped free end of the oviduct bearing finger like processes called fimbriae which help in collection of liberated ovum after ovulation ; ( ii ) Ampulla : The widest and longest part of the Fallopian tube ; ( iii ) Isthmus : Short , narrow , thick - walled portion follow ampulla ; and ( iv ) Uterine part : Passes through the uterine wall and communicates with the uterine cavity .
Uterus
It is an inverted pear - shaped highly elastic large part of female reproductive system where development of fetus takes place
Uterine wall have three layers : Perimetrium , an outer thin covering of peritoneum ; myometrium , middle thick layer of smooth musde fibres that shows strong contraction during delivery of the baby and endometrium , inner glandular layer lining the uterine cavity .
Uterus is differentiated into three regions - The upper dome - shaped region called fundus , the broad main part called body and a small , narrow , cylindrical inferior extremity called cervix . Cervix connect to the vagina through external os .
Vagina The vagina is a tube, about 10 cm long , that extends from the cervix to the outside of the body . It provides a passage for the menstrual flow , serves as the receptacle for sperm during intercourse and forms part of the birth canal during labour .
The opening of the vagina is called the vaginal orifice . It is partially covered in virgins by a perforate membrane called hymen .
External Genitalia . The female external genitalia include the mons pubis , labia majora , labia minora , clitoris , vestibule of the vagina , and vestibular glands . External genitalia are collectively called vulva.
