theories of aging - Coggle Diagram

- - - - bilogocial clock act through hormones that control the rate of aging
      - hormones decline with age
      - they assume if we restore the levels of these hormone it will be an anti-aging strategy
      - hormones like estrogen, growth hormone ,melatonin and testosterone
    - - it is said that the body is designed to wear out
      - the fibroblast can reproduce only 50 times
      - and after 50 times the tellers will be so short and replication cannot occur
    - - there is genes that switch on and off
      - there is biological clock that is controlled by our genes
      - fruit fly if have am not dead yet it will double the lifetime
    - - the immune system decline over age
      - the immune cells then cannot differentiate between the self and non self cells (autoimmune)
  - - - molecules who have free electron will react with healthy molecules
      - like hydroxy radical OH and nitric oxide radical
    - - molecules like proteins and DNA they will attach to each other and decrease the mobility and elasticity of these structures
    - - the cells will tear because of continued use
      - toxins, radiation and other stressors they will harm the DNA in the gene
    - - as mutations in the somatic DNA increase it will lead to the decrease of cellular function
    - - is than the human being once faster use of oxygen the shorter they live
      - have finite number of breaths and heartbeats
      - increased BMI will cause rapid aging and shorter lifespan
      - there is certain metabolic energy in person
