Aging is a natural process of structural decay that all living organisms undergo. It is caused by intrinsic processes (e.g., genomic instability and telomeric attrition) and interactions with the environment (e.g., exposure to sunlight and toxins). As aging is related to and dependent upon living and interacting with the environment, it has been associated with chronology since antiquity.
As human beings get older, the aging process results in many organic changes that must be anticipated and differentiated by the physician from the actual manifestations of a disease. For example, deposition of materials in the arterioles over the years can slightly increase systemic vascular resistance and ultimately blood pressure. On the other hand, the processes related to aging can play a major role in the pathophysiology of degenerative conditions such as Alzheimer’s disease, Huntington’s disease, and Parkinsonism.
For optimal comprehension, the medical student should be familiarized with organelles and their functions, genome replication, epigenetics, the basics of stem cells, and intercellular communication.
Muy bien explicado y presentado por la presentadora, además de diapositivas muy explicitas.
Very interesting lectures. I really injoy the way you explain the topic. Thanks a lot!
It was an effective method to aquire the knowledge required for that interesting topic; thanks so much indeed for such fascinating and entertaining lectures even though I wish you could increase the number of them as I really enjoyed every minute spent learning that session.
Reviewing for my NP certification and this is an excellent resource.
