When you cut down a tree, there are rings on the inside of the tree. You can count these lines to help determine how old the tree is.
The biochemical processes in the order in which they occur during the menstrual cycle.
- FSH and LH stimulate the follicles to develop and the oocyte to produce estrogen.
- Rising estrogen levels suppress FSH production and the development of other follicles.
- Elevated levels of progesterone maintain the endometrial lining of the uterus.
- An LH surge causes the follicle to rupture.
- The breakdown of the corpus luteum causes progesterone levels to drop.
- The endometrial lining breaks down and low estrogen levels stimulate the pituitary gland to release FSH and LH.
<h3>How is the menstrual cycle regulated?</h3>
The menstrual cycle is regulated by the complex interaction of hormones: luteinizing hormone, follicle-stimulating hormone, and the female hormones estrogen and progesterone.
With this information, we can conclude that progesterone is a hormone that is responsible for regulating a woman's menstrual cycle, preparing the uterus to receive the fertilized egg and preventing it from being expelled by the body.

<span>It can be aerobic respiration in the presence of oxygen or anaerobic respiration. Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. More emphasis here will be placed on eukaryotic cells where the mitochondria are the site of most of the reactions.</span>
