This and my other scientific images have now been moved over to Sketchy Medicine.com, my new website dedicate exclusively to scientific and medical images!
I’m doing some more illustration for Sharing in Health, which is great because it forces me to get off my butt and do some art. This one is of placenta previa, a condition in which the placenta develops either over or dangerously close to the cervix. Being, in very very simple terms, a giant sac of blood, this isn’t the best place for the placenta since it’s kind of where the baby needs to go. The danger is that when a woman with placenta previa goes to delivery, the placenta gets all mucked up and she can bleed out. It’s one of the most common causes of maternal death in the world. The good news is that placenta previa can be detected by ultrasound and then a C-section can be preformed, preventing all this nasty bleeding business.
The illustration shows the normal location of a placenta, along with placenta previa and two not-quite-placenta-previa situations that should still be noted.
