Learning from mistakes in the past and using that knowledge to improve the next time around is just a good rule of thumb to abide by in life. According to The Times of Israel, Israeli researchers have said that they have found proof that a woman's body can use this same concept while creating life. Per the research, a woman's body is able to learn from issues that arise in a first pregnancy and will attempt to avoid those same kinds of issues in the pregnancy or pregnancies that follow.
Researchers at Hadassah Medical Center and the Hebrew University of Jerusalem conducted a study over six years on the role of certain cells during the pregnancy period. The study was based on hundreds of samples of mucous membranes. In the results of six years of hard work, researchers found that the cells that are responsible for assisting fetuses implant in the womb and avoid diseases such as preeclampsia or intrauterine growth retardation are more active during a second pregnancy. This, the researchers claim, is because they remember the problems that arose the first time and are better trained to do their job more accurately during subsequent pregnancies.

"It is a known clinical fact that second pregnancies are more efficient than first," Professor Simcha Yagel, the head of the division of Obstetrics and Gynecology at Hadassah Medical Center said in a phone interview with The Times of Israel. "If we know why the second pregnancy is better than the first, then maybe we can do something to help women with high-risk first pregnancies — like after in vitro fertilization or who are older."
Yagel claims that fetuses are known to typically implant better during a second pregnancy and what's more, the babies are generally known to be born bigger and the mother is less prone to diseases such as preeclampsia.
For the most part, the researchers focused their study on "Natural Killer" cells, also known as NK cells. NK cells are present in the immune system of every human being. Their primary job is to be ready and prepared to combat viruses and tumors that may present themselves. The study found that NK cells are also present in the lining of the uterus at the start of a pregnancy. In fact, an estimated 70% of the cells found in the lining of the uterus are NK cells.
The role of these cells in the pregnancy is “very important" according to Yagel. The cells are thought to originate from the bone marrow of the mother and are set into motion during the start of a pregnancy with the purpose of helping the fetus to survive.
Our bodies are truly amazing machines -- and this is just further proof of that!
