Question

Which one of the following sentences is wrong?

• A. Small arteries are called arterioles
• B. When arterioles reach the capillaries blood pressure drops
• C. Blood pressure is lower in the arteries than in the arterioles
• D. Small arterioles regulate the flow of blood into each capillary

Answer 1

The correct option is C

Blood pressure is lower in the arteries than in the arterioles

Arterioles have muscular walls (usually only one to two layers of smooth muscle) and are the primary site of vascular resistance. The greatest change in blood pressure and velocity of blood flow occurs at the transition of arterioles to capillaries.
