Answer 1

Step 1: hCG (Human Chorionic Gonadotropin).
Source: Secreted by the placenta.
Function: hCG stimulates the corpus luteum to continue producing progesterone, which is necessary to maintain the pregnancy.
Step 2: FSH (Follicle Stimulating Hormone).
Source: Secreted by the anterior pituitary.
Function: FSH stimulates the growth and maturation of ovarian follicles and the secretion of estrogen.
Step 3: LH (Luteinizing Hormone).
Source: Secreted by the anterior pituitary.
Function: LH triggers ovulation and the formation of the corpus luteum, which secretes progesterone.
Step 4: Relaxin.
Source: Secreted by the ovaries and placenta.
Function: Relaxin helps relax the uterine muscles and soften the cervix to facilitate childbirth.
