Carotid artery. Carotid artery disease is caused by a buildup of plaques in arteries that deliver blood to your brain. Plaques are clumps of cholesterol, calcium, fibrous tissue and other cellular debris that gather at microscopic injury sites within the artery. This process is called atherosclerosis.
One of the biggest great white sharks ever caught on tape. Before you go, we thought you'd like these... Nicknamed 'Deep Blue,' this great white is almost as long as the 22-foot-long boat the researchers were aboard near Guadalupe, Mexico, nearly 165 miles away from mainland.
According to the Guinness Book of Records, the two largest great white sharks ever found were 36' and 37' feet long. The 36' foot shark was captured off Port Fairy in South Australia in the 1870s, while the 37' shark was caught in New Brunswick, Canada, in the 1930s.
