.....estrogen and progesterone are low
In women, menstrual flow occurs
as a result of the actions of some hormone between the pituitary gland in the
brain and the ovaries. Female sex hormones prepare the body for fertilization
every month and without fertilization there is menstrual flow. Menstruation is activated
by reduced levels of the hormones estrogen and progesterone at the end of the
previous menstrual flow.
<span>Hi,
The food is chewed and grinned up from the teeth and broken down from saliva, then the epiglottis shuts covering the trachea allowing food to travel
down the esophagus, once it travels down it reaches the stomach which is mechanically and chemically broken down from the stomach muscles and the hydrochloric acid. Then it goes into small intestine, then the large intestine where it is determined to be a solid, liquid, or gas and the liquid is normally drained out causing it to be solid, Then it is eventually stored in the rectum and released through the anus. There are three helping organs the liver, gallbladder, and pancreas which produce the digestive enzymes but arent part of the digestive tract,
