A structure connecting the fetus to the placenta, containing vessels and protective gel.

A gelatinous substance found in the umbilical cord, providing cushioning and protection to vessels.

The blood vessel in the umbilical cord that carries oxygenated blood from the placenta to the fetus.

The blood vessels that carry deoxygenated blood from the fetus back to the placenta.

Identical twins formed from a single fertilized egg that splits into two embryos.

Fraternal twins formed from two separate fertilized eggs during the same pregnancy.

Gestations involving two or more fetuses, often referred to as twins, triplets, etc.

Increased health risks associated with pregnancies that have multiple fetuses.

The attachment of the blastocyst to endometrial epithelium about 6 days post-fertilization.

Outer cells of the blastocyst that differentiate into two layers: cytotrophoblast and syncytiotrophoblast.

Inner layer of mononucleated cells in the trophoblast.

Multinucleated outer layer of the trophoblast, highly invasive with no cell boundaries.

Transformation of endometrial stromal cells due to implantation events.

A hormone secreted by syncytiotrophoblast that supports the pregnancy.

The layer of the endometrium that undergoes changes during the menstrual cycle and supports implantation.

Process where the blastocyst becomes deeper in the endometrial layer, confirmed by day 11-12 after fertilization.

Cells derived from the endometrium after implantation that aid in supporting the embryo.

The functional endometrium during pregnancy, involved in nourishing the embryo and immune protection.

Part of the decidua located deep to the embryo, anchoring the villi.

Part of the decidua that forms a capsule over the implanted embryo.

The remaining part of the decidua, excluding the basalis and capsularis.

Stage of trophoblast development where vacuoles merge to form lacunae after implantation.

Dilated, thin-walled maternal capillaries that are eroded by the trophoblast.

Structures formed by the proliferation of cytotrophoblast cells into the syncytiotrophoblast.

Villi that form when the embryonic mesoderm invades primary villi.

Developed villi that contain capillaries and blood cells, crucial for nutrient exchange.

Medications like oxytocin that help control bleeding after childbirth by promoting uterine contractions.

Premature separation of the placenta from the uterine wall, causing bleeding and possible complications.

A pregnancy condition characterized by high blood pressure, protein in urine, and edema.

Severe complication of preeclampsia marked by convulsions in a pregnant woman.

A placenta consisting of two distinct lobes.

A condition where umbilical vessels attach to the amnion before reaching the placenta, leading to risks.

When the umbilical cord slips through the cervix during labor, potentially causing fetal hypoxia.

A condition in MZ twins with unequal blood distribution leading to size discrepancies.

A condition in identical twins caused by incomplete splitting of the embryo, resulting in twins connected by tissue.

A hematoma that forms behind the placenta during placental abruption.

Amniotic fluid supports fetal growth, protects against injury, and aids development.

The fetus swallows amniotic fluid, aiding digestion and lung development.

Waste products from fetal blood are transferred to maternal blood via the placenta.

Aqueous solution containing fetal cells, salts, proteins, and waste by-products.

Fetal kidneys excrete excess water into the amniotic sac as urine.

Helps maintain a constant temperature for the developing fetus.

Amniotic fluid forms a hydrostatic bag aiding in cervix dilation during labor.

Membrane formed by fusion of the amnion and chorion, surrounding the amniotic cavity.

Metabolism, endocrine secretion, and placental transfer between mother and fetus.

The process of substances moving between maternal and fetal blood across the placenta.

Blood flow from the fetus to the placenta through umbilical arteries and back through the umbilical vein.

Blood circulation in the intervillous spaces from maternal blood supply to the placenta.

Finger-like projections that extend from the chorion into the placenta for blood exchange.

Clear fluid surrounding the fetus within the amniotic cavity, essential for protection and development.

Changes from 30ml at 10 weeks to 800-1000ml at term, replenished every 3 hours.

Production of hormones by the placenta, including hCG, progesterone, and estrogen.

The placenta is discoid with a diameter of 15-25 cm and thickness of 3 cm.

Spaces between chorionic villi filled with maternal blood for nutrient exchange.

Breaking of the amniochorionic membrane at labor onset, signaling that labor has begun.
