USS Hatteras 3D Map Shows Civil War Warship 150 Years After It Sank. On this day (Jan. 11) in 1863, a Union warship was sunk in a skirmish with a Confederate vessel in the Gulf of Mexico. Exactly 150 years later, a new 3D map of the USS Hatteras has been released that shows what the remains of the warship look like.
Arteries are blood vessels that supply blood to the tissues of body. They carry the blood away from heart and because the blood inside them is oxygenated, they appear red in color.
ANSWER: Arteries usually carry oxygenated blood from heart to all the parts of the body whereas a coronary artery carries oxygenated blood and supplies it to the heart muscle-myocardium (for its functioning!) and that's where usually angina results as a result of artery thickening.
