0. Summarize the effects of progesterone and estrogen
tino4ka555 [31]

Answer:

Estrogen and progesterone are both involved in preparing the endometrium for embryo implantation. Estrogen helps to ensure conception by increasing the amount of secretory glands in the uterus. Estrogen also increases blood supply to the endometrium.

Progesterone is crucial for embryo implantation and maintenance of pregnancy. Progesterone also enlarges secretory glands that produce carbohydrates, proteins and mucin that are required for embryo nourishment before implantation. Progesterone stabilizes endometrial muscles to prevent them from contracting during pregnancy.

Explanation:

  • Estrogen and progesterone are steroid hormones of the reproductive system. Estrogen helps in conception whereas progesterone maintains pregnancy.
  • Estrogen is secreted during the follicular phase of the menstrual cycle that promotes the growth and maturation of follicles in the ovary.
  • Estrogen also induces oestrous behavior in females.
  • Secreted by the corpus luteum, progesterone is also a steroid hormone, responsible for implantation of the embryo in the uterus.

Dahasolnce [82]

Answer:

Explanation:

A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. Once the fusion reactions begin, they exert an outward pressure.
