Study Notes
Uterus and Fetus
- The uterus is a strong, muscular organ present in women, providing the environment for the developing fetus.
- During childbirth, the mother is encouraged to push down on the uterus to help deliver the baby.
Amniotic Fluid
- The fetus resides in amniotic fluid, which offers a protective and nurturing environment.
- For approximately nine months, the fetus swims in this fluid, leading to questions about oxygen and nutrient intake.
Fetal Needs
- Essential needs for the fetus include:
- Oxygen: Required for survival, yet the fetal lungs are filled with amniotic fluid.
- Nutrients: Such as glucose, needed for energy.
- Waste Removal: Challenges in eliminating waste products like carbon dioxide.
Role of the Placenta
- The placenta serves as a crucial interface between mother and fetus, facilitating nutrient and gas exchange.
- Fetal blood vessels, known as umbilical arteries and an umbilical vein, connect the fetus to the placenta.
Umbilical Cord
- The umbilical cord consists of two umbilical arteries (low in oxygen) and one umbilical vein (rich in oxygen).
- Umbilical veins are depicted as red due to being oxygenated blood returning to the heart, while arteries are blue to indicate deoxygenated blood moving away from the heart.
Wharton's Jelly
- The vessels in the umbilical cord are surrounded by Wharton's jelly, providing support and protection.
