Document Summary
Anatomy 216 (reading material: chapter 27: pages 735-743) Waste removal for the developing embryo and fetus. Uterus: location shape and size anteverted, anteflexion vs retroflexion body. 90% of the mass of the uterus perimetrium: outer layer (visceral peritoneum) Secretes nutrients to baby from uterine gland, this occurs in uterine phase to keep embryo alive. glandular mucosa lining of the uterus. Continues from menarche (first menstrual cycle) to menopause. Shed entire functional layer of uterus in day 0-7 (layer that was thickened in previous cycle) Making endomertrial glands open up and prepare functional zone. Endometrial glands are opened up and are secreting nutrients to help embryo. Rising levels of progesterone and estrogen (if have high estrogen, progesterone will stay low and vice versa) Uterine artery arcuate artery > radial artery > straight or spiral artery. Baby interacts with spiral artery, 6-7% of pregnancy has preeclemsia. -cells from fetus modify spiral artery to be widened!
