Transvaginal ultrasound
When a transducer is placed in the vagina, most often in early pregnancy
Transabdominal ultrasound
When the transducer is moved over the abdomen
Specialized sonographic evaluation
More detailed evaluation when an abnormality is known or suspected
3D ultrasound
2-dimensional display of 3-dimensional data. Can help detect facial abnormalities or neural tube defects
Doppler ultrasound
Measures slight changes as waves bounce off of moving objects, like blood cells. Provides details about blood flow
Fetal echocardiography
Provides a detailed picture of a baby’s heart. Helps confirm or rule out congenital heart defect

Organogenesis
When and how the organs develop
When and how the organs develop
Organogenesis
Anything that causes a birth defect, and can influence the development of a baby
Teratogen
Teratogen
Anything that causes a birth defect, and can influence the development of a baby
What does amniotic fluid do?
Protects the fetus from injury, protects against infection, allows the baby to move and develop properly, controls the temperature.
What substance protects the fetus from injury, protects against infection, allows the baby to move and develop properly, controls the temperature.
Amniotic fluid
What does the amniotic sac do?
Helps protect from injury and regulate temperature
What is amnion?
Membrane that covers the fetal side of the placenta
This is the membrane that covers the fetal side of the placenta
Amnion
This is filled with amniotic fluid and amnion, and helps protect from injury and regulate temperature
Amniotic sac
Placenta
Provides metabolic interchanges between mother and fetus
