Arteries supplying the same territory are often merged with one another, forming arterial anastomoses.

• A. True
• B. False
• C. Only in certain organs
• D. Not a common feature

Answer: (A)

Arteries that supply the same tissue region often connect with each other to form arterial anastomoses, creating collateral pathways. This arrangement provides alternate routes for blood flow if one vessel becomes narrowed or blocked, helping to maintain tissue perfusion. For example, the Circle of Willis links the major cerebral arteries, the palmar arches connect the radial and ulnar arteries in the hand, and mesenteric arteries can form collateral routes in the abdomen. There are exceptions—some organs have end arteries with limited or no anastomosis, so occlusions there can cause ischemia—but overall, arteries feeding the same territory commonly form these connections, so the statement is true.
