To put it in the simplest terms, your body sees the fertilized egg as a parasite or an infection of microorganisms, because it has the combined DNA structure from both mother and father, so the body doesn't recognize it. Antibodies, cells that defend the body from foreign invaders, would destroy the zygote, or fertilized egg, if the uterus didn't develop a mucous lining to shield and protect it. This allows the zygote to stay implanted in the uterus and develop full-term into the baby that is born.
Human embryos develop in the uterus, specifically in the lining of the uterus called the endometrium. The fertilized egg implants itself into the endometrial lining where it will continue to grow and develop into a fetus.
The lining of the uterus
No, you need a hospitable environment for the pregnancy to develop.
The lining of the uterus is shed during the menstrual phase of the menstrual cycle. This is when the body sheds the built-up uterine lining in the absence of a fertilized egg, resulting in menstrual bleeding.
If implantation of a fertilized egg cell occurs in the uterus, the lining of the uterus will thicken and develop structures to support the early stages of pregnancy. This process is essential for the implanted embryo to receive nutrients and establish a connection with the maternal blood supply.
hormone that maintains the lining of the uterus?
The fertilized egg (which develops into a baby eventually) implants itself into the uterine wall/lining. The lining surrounds the egg as it matures and develops into a fetus and a placenta and amniotic sac surrounds the fetus eventually to nourish it.
The lining of the uterus breaking apart is the mucus lining that is usually formed so as to create a conducive environment for a fertilized egg to develop. If the ovum is not fertilized, the thick lining breaks apart which is what causes menstruation.
The lining of the uterus is what denigrates when your egg isn't fertilized and you get your period.
The lining of the uterus serves as a protection for the growing fetus.
No, implantation occurs in the uterus. After fertilization, the fertilized egg travels through the fallopian tube and implants into the lining of the uterus where it will develop into an embryo.
The process when an embryo attaches to the uterus is called implantation. During implantation, the embryo embeds itself into the lining of the uterus, where it will continue to develop and receive nourishment.
