Rationale 1:Constricted arteries increase the peripheral resistance, causing higher blood pressure.
Rationale 2:The lower the peripheral resistance, the lower the blood pressure.
Rationale 3:Higher pressure, by way of constricted arteries, causes an increase in the blood pressure and not lower blood pressure.
Rationale 4:There is a relationship to peripheral resistance and blood pressure.
Global Rationale: As blood flows at high speed through the vascular system, it bumps and drags across the walls of the vessels. The dragging or friction in the arteries is called peripheral resistance. Arteries have smooth muscles in their walls and when constricted, will cause the inside diameter or lumen to become smaller, creating more resistance and higher pressure.
