Chapter 21 – Open Book Worksheet Questions

According to Poiseuille's law,

• blood flow is not related to resistance.

• pH of the blood influences flow.

• viscosity of the blood is not related to flow.

• if resistance increases, flow increases.

• if resistance increases, flow decreases.

Which of the following sequences is correct?

• external iliac vein, internal iliac vein, common iliac vein

• liver sinusoid, central vein, hepatic vein

• superior vena cava, azygos vein, posterior intercostal vein

• fibular vein, femoral vein, popliteal vein

• hepatic vein, hepatic portal system, inferior vena cava

The hepatic portal vein is formed by the union of the splenic vein and the

• superior mesenteric vein.

• inferior mesenteric vein.

• hepatic vein.

• renal vein.

• gastric vein.

The azygos vein drains blood from the _____ into the superior vena cava.

• head

• upper arm

• kidneys

• thorax

• abdominal wall

The longest vein in the body is the

• superior vena cava.

• inferior vena cava.

• hepatic portal vein.

• great saphenous vein.

• femoral vein.

Increased venous tone will

• relax the veins.

• help return blood to the heart.

• allow blood to pool in the veins.

• stabilize blood velocity in the veins.

• dilate the veins.

Which of the following is LESS likely to result in edema?

• increase in capillary permeability

• reduced plasma colloid osmotic pressure

• blockage of veins

• increased mean arterial pressure

• loss of protein molecules in urine through the kidneys

What creates the pulse?

• the diastole of the ventricles

• ejection of blood from the left ventricle into the aorta

• the compliance of the arteries

• constriction of the arterioles

A thrombus in the second branch (not including coronary arteries) off of the aortic arch would affect the flow of blood to the

• left side of the head and neck.

• myocardium of the heart.

• right side of the head and neck and right upper extremity.

• left upper extremity.

• right arm.

Systemic circulation

• carries blood from the right ventricle to the lungs.

• includes all arteries but the veins are part of the pulmonary circulation pathway.

• includes the aorta and all of its branches.

• ends in capillaries of the toes.

• includes blood flow to the body, but not the brain.
