HORMONES!
This organ takes over progesterone production from the corpus luteum during the first trimester
What is the placenta?
This measure of blood pumped per minute increases during pregnancy
What is cardiac output?
Delivery of the placenta causes this hormone to fall, allowing for full-fledged milk production
What is progesterone?
This hormone maintains the corpus luteum during early pregnancy
What is hCG?
An increase in this renal filtration measure lowers maternal serum creatinine
This posterior pituitary hormone strengthens contractions through increased intracellular calcium
What is oxytocin?
This hormone maintains the decidua and promotes uterine relaxation
What is progesterone?
Progesterone increases ventilation primarily by increasing this volume per breath
What is tidal volume?
Increased expression of these intercellular channels allows uterine smooth muscle cells to contract together
What are gap junctions?
This outer, multinucleated trophoblast layer secretes hCG
What is the synctiotrophoblast?
Reduced lower esophageal sphincter tone increases this common pregnancy symptom
What is GERD/Acid Reflux?
These locally produced lipid mediators ripen the cervix and stimulate uterine contractions
What are prostaglandins?
This placental hormone increases maternal insulin resistance, helping preserve glucose for the fetus
What is Human placental lactogen (hPL)
Changes to ventilation produces this primary acid–base disturbance during pregnancy
What is respiratory alkalosis?
Cervical stretch promotes oxytocin release through this positive-feedback reflex
