Untreated Depression and Shortened Telomeres Untreated depression creates biological changes that accelerate aging and increase the risk of life-threatening diseases. Major Depressive Disorder (MDD) can shorten the length of telomeres. A team led by Owen Wolkowitz, MD, professor of psychiatry at UC San Francisco (UCSF) has been studying the biological link between chronic depression and an enzyme called telomerase which is linked to shorter telomeres.
The major organs of the body are simply the most well known organs but may not be important if they work alone, as they need to work in co-ordination with all other organs in the body.Starting at the top of the human body, the brain processes information and is the bodyâs control center.It handles the processes of the central nervous system and cognition. The eyes detect light and convert it into electrical signals which the brain interprets as vision. The chest cavity contains some major organs.The heartâs main function is to use the circulatory system to pump blood through out the body. The lungs oxygenate blood through the intake of air and filter out any contaminants from the air which they consider harmful to the bloodstream.tarting at the top of the human body, the brain processes information and is the bodyâs control center.

Systems of the human body. Skin and nails are part of the integumentary system that helps protect the body. Earthworms have organ systems that help them move, breathe, and digest food. The endocrine system is responsible for producing and regulating hormones in the bloodstream to control bodily functions.The urinary system is a type of organ system that allows the body to rid itself of waste. The respiratory system is made up of the mouth, throat, nose, sinuses, bronchial tubes, and lungs.The torso houses many of the human body's organ systems.n biology, an organ system is a group of organs that work together for one purpose. Their interdependency on one another is critical for normal life functions, and if any one were to fail, it would subject the others to stress, possibly causing the whole group to shut down, with fatal results.
