• Anucleated


  loses nuclei as they age
• 120 days

  -act as a filter against microbes
• lymph nodes


  creates or release lympocytes

  -the colorless fluid in lymph

  -travel through lymph vessels
• thymus gland

  lower than 120
• Atherosclerosis


  loses the arteries elasticity

  "bad" form of cholesterol that can leave deposits on the walls of your blood vessels
• high density lipoprotein


  "good cholesterol";transports cholesterol from the arteries to the liver
• aneurysm


  bulge in the arteries
• stent
