Find images of the uterus on MedlinePlus, which is maintained by the U.S. National Library of Medicine, and on Wikipedia, which is an open-source online encyclopedia. The uterus is a muscular organ in the female pelvis where a fertilized embryo implants itself. It nourishes the developing fetus until the baby's birth.
MedlinePlus features two illustrations. The first one is a diagram that shows the location of the uterus in relation to nearby anatomical parts, such as the fallopian tubes, ovaries, internal orifice, external orifice and vagina. The second illustration shows the location of the uterus and its associated organs within the female body.
Wikipedia also features several images of the uterus in anterior, lateral and saggital views. The uterus has two parts: a body and a cervix, and it has three layers: the inner endometrium, the middle layer of smooth muscle known as the mesometrium and the loose outer connective tissue known as the perimetrium. The shedding of the endometrial lining is responsible for menstrual bleeding. The frontal view illustration also shows the position of several ligaments that hold the uterus in place inside the pelvis.
Wikipedia also shows an ultrasound image of uterine fluid accumulation in a postmenopausal woman. Another illustration details the organ's rich blood supply. Additional illustrations show how the uterus gradually expands during pregnancy and an image of an actual uterus with its labeled parts.
