Study Notes

Cellular Aging

  • As cells age, their function declines.
  • Cell death is a normal part of the body's functioning.

Organ Aging

  • A decline in one organ's function can affect another organ's function.
  • Atherosclerosis, a condition that narrows blood vessels, can decrease blood flow to the kidneys, impacting their function.

Aging Cells

  • Cells age, their functions decline over time.
  • Old cells die as part of normal body function.

Aging Organs

  • Decline in one organs function can affect another.
  • Reduced blood flow to kidneys from narrowed blood vessels (atherosclerosis) can impact kidney function.
