Estrogen :thickens the endometrium,inhibits the action of FSH & LH Progesterone :thickens the endometrium ,inhibits the action of LSH&LH in the luteal phase and stimulated LH secretion in follicular phase
Uterus lining (endometrium ) thickens during the proliferative phase of the cycle due to progesterone,if there’s no pregnancy the level of progesterone and estrogen decreases (due to breakdown of corpus luteum ) hence resulting into degeneration of the endometrium (Ischemic phase )
Estrogen and Progestrone harmone help in the thickening of the inner wall of the uterus i.e. endometrium layer,for the reception of fertilized eggs and their development.
Progestrone prepares the uterus for a fertilizef egg to implant.
The uterus lining sheds if no fertilization occured because the sperm passes through the uterus so.the lining of the uterus again starts to break down and shed ,and new mestural period begins
In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxygen.
