Blood pressure is controlled by various anatomic structures - match the structure to the aspect of BP they control...

• arterioles

• Rate (bpm) & Cardiac output (L/min)

• venules

• Blood volume

• heart

• resistance

• kidneys

• Capacitance (ability to increase blood volume w/o a large increase in BP
