oviduct

 [o´vĭ-dukt]
2. in nonmammals, a passage through which ova leave the maternal body or pass to an organ communicating with the exterior of the body. adj., adj ovidu´cal, oviduc´tal.

u·ter·ine tube

[TA]
one of the tubes leading on either side from the upper or outer extremity of the ovary, which is largely enveloped by its expanded infundibulum, to the fundus of the uterus; it provides the path by which the ovum travels from ovary to uterus where, if it is fertilized in the tube, it will implant as a zygote; it consists of infundibulum, ampulla, isthmus, and uterine parts.

oviduct

(ō′vĭ-dŭkt′)
n.
A tube through which eggs pass from an ovary, such as a fallopian tube in a mammal.

o′vi·duc′tal adj.

oviduct

Medspeak
Fallopian tube; tuba uterina [NA6].
  
Zoology
The duct through which eggs pass to an animal’s exterior.

u·ter·ine tube

(yū'tĕr-in tūb) [TA]
One of the tubes leading on either side from the upper or outer extremity of the ovary, which is largely enveloped by its expanded infundibulum, to the fundus of the uterus; it consists of infundibulum, ampulla, isthmus, and uterine parts.
Synonym(s): salpinx (1) [TA] , fallopian tube, gonaduct (2) , oviduct.

oviduct

a tube that carries the egg to the exterior or, in the case of mammals, to the lower part of the tube, the UTERUS, where it becomes implanted in the wall lining (ENDOMETRIUM) if FERTILIZATION has occurred. Usually oviducts are paired, but only one is present in birds. In higher mammals it is divided into an upper FALLOPIAN TUBE, which is ciliated, and into which the egg passes from the COELOM, a middle uterus, where the embryo develops, and a vagina leading to the exterior.

Patient discussion about oviduct

Q. She had an infection in her fallopian tubes. She is recovering now, but can she get pregnant again? My sister had a very bad pregnancy where she had lost her first child. She had an infection in her fallopian tubes. As it was an ectopic pregnancy, she had an operation where they made a small incision in the fallopian tube and removed the embryo. She was depressed for quite a while as she was looking forward to enjoying her new baby. She is recovering now, but can she get pregnant again?

A. i think that was an ectopic pregnancy. of course she can get pregnant again, although the past history of tubal pregnancy increases the risk of developing another ectopic pregnancy in the future. but don't worry, all your sister need to is always consult her health and future-pregnancy condition with her ob-gyn specialist.

i believe that what happened to your sister was non-complicated ectopic pregnancy, because the doctor was just doing the minimal invasive surgery in her fallopian tube. it still has the risks of having another ectopic one in her future pregnancy, but with a complete medical check-up and work-up, i'm sure she will just be doing well.

i just wrote a brief note about ectopic pregnancy, in case you want to read that :

The oviduct is a dynamic organ comprising different anatomical and functional regions that may show differences in mRNA expression levels and in the synthesis and secretion of various proteins (Maillo et al., 2016).
The mRNA expression levels of yak ERs were predominant in the mammary gland, uterus, and oviduct and showed low expression in the liver, heart, spleen, lung, kidney, and testis.
The mesoderm-derived dorsal region moved close to and became continuous with the oviduct. The main change was the extensive reduction of the dense layer.
In an atypical fish, the feminization process is probably completed at a physiological level, but the channel associated with the oviduct is not properly formed and the genital papilla retain its male form.
The females with vaginal plug were sacrificed and the zygotes were transferred in to the isolated oviduct at 20 hpi.
The connection of the spermathecal reservoir to the common oviduct is made via a short muscular duct with circular muscles (Figure 2E, F).
Strong expression of LIN28B mRNA was found in the hypothalamus, pituitary, ovary and oviduct; moderate expression was found in the spleen, kidney and liver; weak expression was found in the heart; and no expression was found in the lungs.
The skin was incised and the mass exposed and confirmed to be a developing egg within the oviduct that had herniated through the left lateral body wall (Fig 3).
Neurons and small ganglia were identified in the UVJ of the turkey and chicken oviduct, and nerve fibres appeared to terminate on individual sperm storage tubules (Freedman et al., 2001), suggesting that neural factor may regulate sperm storage in and release of spermatozoa from the SST of hens.
Besides, lymph and a few lymph nodes are also included.13 Sensory nerves of the uterus and oviduct enter pelvic plexus through sacrospinous ligament and cardinal ligament.
(A) Female reproductive system of Scyphophorus acupunctatus formed by 2 ovaries (ov), germarium (g), vitellarium (v), oocyte (o), lateral oviduct (lo), common oviduct (co), spermatheca (s), and genital chamber (gc); (B) Distal part of the germarium (g) with bulky appearance possibly with trophocytes, prefollicular cells, and oogonia, terminal filament (tf), trachea (tr), tracheoles (trl); and (C) Approach to the onset of vitellarium with oocytes in development, germinal vesicle (gv), interfollicular tissue (tif), trachea (tr), and tracheoles (trl).
The fallopian tubes or oviducts are two muscular tubes which extend from uterus to the ovaries.
