Pregnancy can be an emotional roller-coaster. The hormones that run through your body affect your emotions, and a pregnancy can be a great experience. However, it can also cause complications, such as preeclampsia.

During pregnancy, the placenta and uterus grow. These tissues provide nutrients and protection for the foetus. In fact, the placenta is the primary source of nourishment for the fetus. It contains a thin, slender sac called the amniotic sac. This sac helps the fetus stay warm during the pregnancy.

It is important to keep a close eye on your health and the condition of your baby. If you feel like you have symptoms, it’s best to see your doctor right away.

While the placenta and uterus are preparing for the birth of a child, the immune system is dialed down to protect the baby. Some studies have linked maternal autoimmune disorders to having a baby. A pregnant mother is at higher risk of infection, and may have to undergo special care.

Despite the many changes to your body, it’s important to remember that pregnancy is also good for your brain. Various changes in your hormones and the growth of your arteries may improve your mental health.

Your arteries expand during pregnancy. This causes your blood pressure to rise. Keeping it low may help lower your risk of heart disease and diabetes.

The arteries in your body are small, twisting things that run in your uterine wall. They capture more of your blood, which means that your fetus has more of the nutrients it needs to grow.
