Fetal Growth and Development

Fetal development refers to the process of growth and development of a fetus in the uterus from conception to birth. Understanding fetal development is important in neonatology, as it provides insight into the normal course of pregnancy and helps in identifying abnormalities or problems that may arise during the neonatal period.

Lesson 1: Fetal Development Stages

• The three stages of fetal development: germinal, embryonic, and fetal stages.
• Duration and key events during each stage of development.
• The role of the placenta and umbilical cord in fetal development.

Lesson 2: Fetal Circulation and Gas Exchange

• The fetal circulation system and how it differs from postnatal circulation.
• The role of the ductus arteriosus, foramen ovale, and ductus venosus in fetal circulation.
• The process of fetal gas exchange and how it differs from postnatal gas exchange.

Lesson 3: Factors Affecting Fetal Growth and Development

• Maternal factors that can affect fetal growth and development, such as nutrition, maternal age, and lifestyle choices.
• Fetal factors that can affect growth and development, such as genetic abnormalities and fetal distress.
• Environmental factors that can affect fetal growth and development, such as exposure to toxins and pollutants.
