Study Notes
Signs of Healthy Development on Ultrasound
- Fetal Heart Rate typically ranges from 120 to 160 beats per minute; a consistent rhythm indicates normal development.
- Fetal Movements, such as limb flexion and extension, suggest a healthy nervous system.
- Measurement of Gestational Age uses the size of the baby's head, abdomen, and femur to estimate age and ensure appropriate growth.
- Placental Position and Thickness should reflect proper attachment to the uterine wall and adequate thickness for nutrient and oxygen exchange.
- Amniotic Fluid Levels must be sufficient to indicate healthy kidney function and fetal swallowing processes.
- Organ Development includes assessing the heart, brain, kidneys, and bladder to confirm proper formation and functionality.
- Umbilical Cord Blood Flow is evaluated via Doppler ultrasound to ensure adequate oxygen and nutrient supply to the fetus.
Role of the Placenta
- Nutrient and Oxygen Transfer occurs through the placenta, linking the mother and baby for essential nutrient delivery and oxygen exchange via the umbilical cord.
- Waste Removal enables the elimination of waste products, such as carbon dioxide and urea, from the baby's bloodstream back into the mother's circulation.
- Hormone Production is essential for maintaining pregnancy, with the placenta generating hormones like human chorionic gonadotropin (hCG), progesterone, and estrogen.
Substances Crossing from Mother to Baby
- Oxygen is essential for fetal development and crosses the placenta from the mother's bloodstream to the baby.
- Nutrients, including glucose, amino acids, fatty acids, vitamins, and minerals, are transferred from mother to baby to support growth and development.
- Antibodies are maternal antibodies that provide passive immunity to the baby during early life stages.
- Hormones such as insulin and thyroid hormones influence fetal growth and metabolism by crossing the placenta.
