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.
You might not be brave enough to dive with this 20-foot-long shark, but filmmakers have. And the footage is incredible. Deep Blue, believed to be the largest ever filmed, was found near Mexicoâs Guadalupe Island, a volcanic island that lies approximately 150 miles off the west coast of Mexicoâs Baja California Peninsula.
