In both instances, epithelium serves the general functions of protection, absorption, secretion, and specialized functions such as movement of substances through ducts, the production of germ cells, and the reception of stimuli. If it were not for the neuromuscular waves of propulsion initiated in the heart that are transmitted along the aorta and other major arteries and arterioles, the contractive force of the ventricles would be irrelevant. That is, because the circulatory system is hundreds of miles in length, a strong heart in a severely vasospastic or atherosclerotic arterial system will soon be bankrupt. DNA and RNA are the cellular components controlling heredity, and the subsequent ability of the body to keep reproducing its genetic pattern. These strands of acid within the cell nucleus govern all life processes in health and disease.
Several studies report excellent results by using a dietary regimen rich in nucleic acids.
While dosage varied, it was usually 3.5 grains of RNA daily for five days a week. In this study, changes noticed during the first week were first recognized in the skin of older patients.
