Document Summary
Sperm & ovum form a zygote when they meet & egg become fertilized. Happens in the fallopian tubes but implants in the endometrium. Once the ovary has been released by ruptured follicle, follicle then continues to function in other ways. Corpus luteum secretes progesterone & moderate levels of estradiol to help w preparation of early pregnancy. Once ruptured, if the egg doesn"t become fertilized, then luteum turns into the albicans. Once embryo develops, placenta takes form; supplies nutrition of the developing fetus. Mucus plug forms in the cervix; formed by the uterus; function is to prevent any microbes or foreign materials from entering the uterine cavity. Embryo: is the developing pregnancy from conception to end of 8th week. Fetus is developing pregnancy from beginning of the 9th week till birth. Presence of hcg (human chorionic gonadotropin) in mom"s plasma or urine hcg is produced by chorionic villi. Lmp = 1st day you miss your period.
