a fertilized ovum usually implants in the fundus part of the uterus.
in what part of the uterus does a fertilized ovum usually implant in?
fundus
the uterus or womb is a hollow, muscular organ where a fertilized egg (ovum) will implant itself and grow into a fetus. the uterus lies in the pelvic cavity between the bladder and the bowel, and above the vagina. it is usually positioned in a 90-degree angle tilting forward, although in about 20% of women it tilts backwards. the uterus has three layers; the innermost layer is the endometrium, where the egg is implanted. during ovulation, this thickens for implantation. if implantation does not occur, it is sloughed off during menstruation. the cervix is the narrow end of the uterus. the broad part of the uterus is the fundus.
human sexuality
the reproductive function of the uterus is to accept a fertilized ovum which passes through the utero-tubal junction from the fallopian tube. the fertilized ovum divides to become a blastocyst, which implants into the endometrium, and derives nourishment from blood vessels which develop exclusively for this purpose. the fertilized ovum becomes an embryo, attaches to a wall of the uterus, creates a placenta, and develops into a fetus (gestates) until childbirth. due to anatomical barriers such as the pelvis, the uterus is pushed partially into the abdomen due to its expansion during pregnancy. even during pregnancy the mass of a human uterus amounts to only about a kilogram (2.2 pounds).
