Fallopian/Uterine Tube
Synonyms : fallopian tubes, Uterine tubes, salpinx (pleural  :  salpinges)
Two very fine tubes that extend laterally from  near the fundus towards the ovaries for the purpose of collecting the ovum  released by the ovary at the time of  ovulation

Different parts of the tube  : infundibulum with fimbrae, ampulla, isthmus that connects the ampulla to the uterus, interstitial part (intramural part that traverses the uterine musculature)
The ostium is the point where the tubal canal  meets the peritoneal  cavity
Uterine opening is the entrance into the uterine cavity, the uterotubal junction

Four distinct layers:
Serosa - derived from visceral peritoneum
Subserosa - loose adventitious tissue, blood vessels, lymphatics, an outer longitudinal and inner circular smooth muscle coats
Lamina propria - vascular connective tissue
Mucosal  layer - the inner most layer of the  Fallopian tube (oviduct) has both simple  and ciliated columnar epithelium, the latter predominantly

The fimbriated end Captures the ovum (secondary oocyte) which is released  by the ovary.
Transmits the ovum to the ampulla where sperms meet it and fertilize and then the zygote is passed on to the uterine cavity
The peg cells in the tube produce  tubular fluid which contains nutrients for spermatozoa, oocytes and  zygotes
The secretions of the tube promote capacitation of the sperm  by removing glycoproteins and other molecules from the plasma menbrane of the sperm
Tubal fluid flows against the action of the ciliae, that is toward the fimbrial end

Applied Anatomy
Tubal block by infections like gonorrhoe etc leads to infertility
Embedding of the zygote in the tube itself instead of the uterine cavity leads to tubal pregnancy (ectopic pregnancy), consequent rupture of the tube and hemoperitonium, and the serious outcome that follow.
Tubectomy : bilateral tubectomy done to sterilize the patient in family planning
