Final answer:
The process of becoming pregnant involves interactions between hormones from the brain and ovaries that prepare the body for pregnancy.
Step-by-step explanation:
The process of becoming pregnant involves the release of hormones from the brain and ovaries that interact to prepare the body for pregnancy. The pituitary gland, located in the brain, releases follicle-stimulating hormone (FSH) and luteinizing hormone (LH) that stimulate the ovaries. These hormones promote the growth and maturation of eggs in the ovaries and the release of one mature egg during ovulation. Additionally, the ovaries produce estrogen and progesterone, which prepare the uterus lining for implantation of a fertilized egg.
