What does the embryo attach itself to?
In humans, the embryo attaches itself to the uterine lining. This process is called implantation, where the fertilized egg burrows into the endometrium of the uterus for nourishment and development during pregnancy.
What is the fertilized egg called during implantation?
The fertilized egg is called a blastocyst during implantation. The blastocyst is a multicellular structure that forms from the fertilized egg as it develops and prepares for implantation in the uterine lining.
Why does a womens uterus thicken?
Progestrone causes the uterine lining to thicken in preparation of a fertilized egg. If no egg is fertilized, the thick lining is shed as a menstrual cycle.

What hormone secreted by the ovaries encourages the rebuild of the uterine lining?
The hormone secreted by the ovaries that encourages the rebuild of the uterine lining is estrogen. This hormone plays a crucial role in the menstrual cycle, stimulating the thickening of the uterine lining in preparation for potential implantation of a fertilized egg.
What does progesterone stimulate?
Progesterone levels rise after ovulation to protect the fertilized egg and to prevent the uterine lining from shedding.
When the fertilized ovum implants in the uterine lining it becomes?
The answer to your question is a zygote. From there, it develops to an embryo and a foetus. Happy science!!!
