Final answer:
Fetal development refers to the growth and maturation of a fetus during pregnancy. It consists of the embryonic stage and the fetal stage. Prenatal care is essential for monitoring the pregnancy and promoting healthy development. Known teratogens can cause birth defects and developmental issues.
Step-by-step explanation:
Fetal development refers to the process of growth and maturation of a fetus during pregnancy. It consists of several stages, including the embryonic stage and the fetal stage.
During this stage, which lasts from conception to 8 weeks of gestation, the major organs and body systems begin to form. The embryo develops a beating heart, a brain, and starts to develop limbs.
After the embryonic stage, the developing human is called a fetus. This stage lasts from 9 weeks of gestation until birth. In this stage, the fetus grows rapidly and continues to develop its organs and systems. By the end of the fetal stage, the fetus is fully formed and ready for childbirth.
Prenatal care refers to medical and health services provided to pregnant women to ensure the well-being of both the mother and the developing fetus. It is important because it allows healthcare professionals to monitor the pregnancy, detect any potential issues early on, and provide appropriate interventions or treatments to promote a healthy pregnancy and fetal development.
Teratogens are substances or factors that can cause birth defects or interfere with normal fetal development. Some known teratogens include alcohol, tobacco smoke, certain medications, infections, and radiation. These teratogens can cause a wide range of damage to the developing fetus, including physical abnormalities, cognitive impairments, and developmental delays.
