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.
The largest on record measured 12 metres in length. But thereâs no need to panic â this gentle giant is a plankton eater. Not only is the whale shark the largest living shark, itâs also the largest living fish period. A typical whale shark measures 5.5 to 10 metres in length. The largest on record, caught off Pakistan in 1947, was over 12.5 metres in length. It weighed 25,400kg â around 4 times larger than a large male elephant!
