Live physiology is a channel optimized for learning the fascinating biological science behind how the human organism sustains life. This channel provides a multitude of videos covering cellular and organismal control components that regulate homeostasis, a key principle in the study of human physiology. The foundations of the science of physiology are covered in a way that anyone studying biomedical science or any life science can benefit, whether studying nursing, a physician assistant program, exercise science, or any branch of biological sciences. Also, the material is straightforward enough, a curious member of the general public can gain insight into the biological mechanisms of systems biology and physiology. None of the videos presented on the YoutTube channel Live Physiology are for medical diagnosis purposes or for health advice. All videos on the RU-vid channel Live Physiology are for entertainment purposes only.
What is the cause that lets LDL cholesterol into intima of blood vessels and arteries? Also if it occurs only when LDL cholesterol is high, why doesn't it happen when the level is optimal. Thank you!
The process begins with damage to the wall of the blood vessel. Optimal levels of LDL are meant to decrease risk of atherosclerosis, but it is not an absolute guarantee that atherosclerosis will not happen. It simply decreases the risk.
