A pregnant woman should realize that her behaviour directly affects the fetus inside her. Blood cells are primarily responsible for transporting nutrients, oxygen and potential teratogens from the mother’s placenta to the fetus, via the umbilical cord. There are many such maternal factors like diet, physical activities, stress, sleep, disorders like diabetes, hypertension etc. which affects the fetus directly or indirectly.There are many harmful substances the mother can ingest or become exposed to that can have negative and harmful effects on the fetus, as well certain vitamins and minerals that can promote prenatal development. In some cases it may be very fatal. Hence, a lot of care should be taken during the pregnancy as it is the most critical period.
