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.
