Congrats, Queen Bey, on your babies, from our uterus to yours!
Birth is an incredible process directed by hormones and carried out by your organs. Typically, childbirth is kicked off by stress -- at the end of gestation, baby is running out of room and wants to get out. Corticotropin-releasing hormones and cortisol from baby's adrenal glands send an evacuation notice to mom's body: "GET ME OUTTA HERE!" The cortisol then pumps up estriol, a type of estrogen present during pregnancy. Estriol slows down progesterone made by placenta and helps co-ordinate uterine contractions. As estrogen starts contractions, the uterus makes prostaglandins, which also force progesterone levels down. Prostaglandins also make you poop and, along with the hormone relaxin (yes, this is a real, actual hormone name) from the ovaries, get the cervix to soften and dilate to let baby through to the vaginal canal. And that's just the beginning!
ENTs and OBGYNs alike will rejoice in four new plush pals -- introducing cervix plush (she's a real pap star), sinus stuffie (it truly puts the "stuffed" back into "stuffed animal"), muscle plush (we're bringing flexy back) and inner ear plushie (fear the ear)! Grab a gut for your gym rat friend, your gyno, your favorite Ear Nose and Throat doc. Each comes with an XL hangtag packed with details about the organ.
