Pregnant Woman at Week 16 of Gestation, Lateral View (Caucasian Skin)

Description

This lateral projection of a pregnant woman's torso renders the maternal abdominal wall and pelvic outline semi-transparent so that the gravid uterus and its contents remain the focus. A fetus at approximately 16 weeks of gestation lies in a flexed attitude within the amniotic sac, the head directed anteroinferiorly and the limbs drawn toward the trunk, with the umbilical cord looping from the ventral abdominal wall of the fetus to the placental disc applied to the uterine wall. The uterine fundus has risen above the pelvic brim toward the level between the symphysis pubis and umbilicus, displacing loops of small intestine superiorly and posteriorly. The sigmoid colon and rectum are visible behind the uterus, while the urinary bladder sits anteroinferior to it, compressed against the pelvic floor. The side view is the most economical way to demonstrate how second-trimester uterine growth remodels the maternal abdomen and pelvis. It shows the anatomical basis of fundal height measurement, the upward displacement of bowel that contributes to constipation and reflux, and the anterior bladder compression that explains increased urinary frequency. Placental position relative to the uterine wall, as depicted here, underpins discussion of placental localisation on mid-trimester ultrasound and of anomaly screening performed around this gestational age, when fetal biometry and gross morphology become reliably assessable. The image suits obstetric and midwifery teaching sequences that track gestation week by week, antenatal class handouts, and patient-facing material explaining what is happening at the sixteenth week. It also serves textbook and journal figures on maternal adaptation to pregnancy, app and website timelines, and pharmaceutical or device communications aimed at prenatal care. As one frame in a matched weekly series, it allows educators to compare fetal size, position and maternal contour across gestation using consistent anatomy.
