A. Conjoined twins occur every 200,000 live births, according to the University of Maryland Medical Center, but about 40-60% of them are still born and only about 35% survive one day. Conjoined twins have identical genetics, which also means they are always the same sex. They develop from the same fertilized egg, amniotic cavity, and placenta. 70% of conjoined twins are girls and girls tend to live longer. Conjoined twins happen when a woman produces a single egg, but does not fully separate after fertilization. The embryo starts to split into identical twins but stops before the process is complete. Surgery is very difficult and rare for conjoined twins and only about half survive.
B. Brittany and Abby are conjoined twins with one body and two heads. They have two separate brains, hearts, and set of lungs, but share everything else. Abby controls the right side of the body and Brittany controls the left. When one gets sick, so does the other. They may share the same body but they are completely different people. Abby is more outspoken, and Brittany is more laid back and has a weird sense of humor. One thing these two strongly dislike is when people stare at them and take pictures.
C. When you watch this video you will see how we'll they work together through everyday challenges. In this video they just turned 16, but now they are healthy 22 year olds, and graduated from Bethel University. ***Show video***
Conclusion: Today I told everyone some facts about conjoined twins, a little bit about Brittany and Abby Hensel, and showed a short video. Hopefully...
