Explain why venipuncture is a common clinical procedure for obtaining blood for examination
What will be an ideal response?
In venipuncture, blood is collected from a superficial vein. Venipuncture is a common clinical procedure because superficial veins are easy to locate, the walls of veins are thinner than comparable sized arteries, and blood pressure in the venous system is relatively low, so the puncture wound seals quickly.
