Chapter 20 part 1

Which vessels have the lowest pressure

• Capillaries

• Arteries

• Venules

• Veins

The following vessels have the greatest elastic recoil

• The great saphenous vein

• Inferior vena cava

• Aorta

• Radial artery

A predominance of oxygenated blood can be found in the

• Pulmonary artery

• Great saphenous vein

• Inferior vena cava

• Pulmonary vein

The primary difference between veins and arteries is the

• tunica intima

• tunica media

• tunica externa

• tunica adventitia

Blood flow (F) increases with

• decreased resistance

• increased resistance

• a smaller difference in pressure

• greater viscosity

Vascular resistance can be increased with

• vasodilation

• vasoconstriction

• decreased friction

• decreased vessel length

Auscultating a bruit is evident of

• a patent vessel

• turbulance due to plaque deposits

• laminar blood flow

• greater viscosity of blood

doubling the radius of a vessel results in a _____-fold increase in flow

• 2

• 4

• 8

• 16

A patient has a BP of 129/80. They have

• normal blood pressure

• elevated blood pressure

• stage 1 hypertension

• a hypertensive crisis
