C: Veins
Answer: C: Veins 
Explanation: The largest compliance in the circulatory system is of veins. Vascular compliance/capacitance is the total quantity of blood that can be stored in a given poion of the circulation for each mmHg pressure rise. vascular compliance= Distensibility * Volume The compliance of a systemic vein is about 24 times that of its corresponding aery because it is about 8 times as distensible and has a volume about 3 times as aery (8*3=24) Ref: Guyton and Hall 13th edition Pgno: 179
