Blood vessel 2.0

_______capillaries have pores within each endothelial cell.

Fenestrated

Which statement accurately compares filtration & reabsorption?

Filtration involves bulk flow of fluid out of the blood, whereas reabsorption is bulk flow back into the blood.

Which carries blood from the liver to the inferior vena cava?

Hepatic veins

The artery that bifurcates into the right subclavian artery & the right common carotid artery is the:

brachiocephalic artery

Valves in veins:

cause venous blood flow to go in only one direction

High carbon dioxide levels & low pH in blood of the carotid arteries will stimulate:

chemoreceptors to activate the vasomotor center

The end of the aorta occurs when the vessel bifurcates into the:

common iliac arteries

Systolic blood pressure is recorded in:

in arteries and is the maximal pressure that is recorded during ventricular contraction.

Increased cardiac output ______ the blood pressure.

increase

Excitation of the vasomotor center results in:

increased sympathetic activity and predominantly more vasoconstriction than vasodilation.

Which statement is accurate about veins?

the largest tunic in a vein is the tunica externa

An increase in will result in an increase in blood flow to an area.

vessel diameter

Blood pressure is lowest in:

veins

If someone's blood pressure were listed as 141/90 mmHg, then their pulse pressure would be:

51

Which can be used to characterize blood flow in the human body? There is a unidirectional blood flow. Arteries always carry oxygenated blood. Veins always carry deoxygenated blood. Arteries carry blood away from the heart. Veins carry blood toward the heart.

A D E

The aorta contains specialized sensory nerve endings that respond to stretch of the vessel wall. These pressure-sensitive structures are called aortic arch ______

Baroreceptors

The _______ vein runs alongside the lateral aspect of the upper limb & eventually drains into the axillary vein.

Cephalic

Which path of arteries would a blood cell follow on its way from the thigh to the ankle?

External iliac a., femoral a., popliteal a., anterior tibial a.

A portal system:

blood flows through two consecutive capillary networks before returning to the heart

The popliteal artery supplies the:

knee joint

Aldosterone & atrial natriuretic peptide have ________ effect(s) on blood pressure.

opposite

The hepatic _____ system is a venous network that drains the GI tract & delivers blood to the liver

portal

Blood colloid osmotic pressure is largely due to the:

proteins in the blood, & it promotes reabsorption

considering the bulk flow that occurs at capillary beds, the lymphatic system is needed to:

reabsorb excess fluid from the interstitial fluid.

Circulation to the spleen goes directly to it then back to the heart. This demonstrates a(n):

simple pathway, as one artery delivers blood & one vein drains the organ

At a capillary bed, a vasoconstrictor:

stimulates precapillary sphincters and decreases local blood flow.

The artery that arises from the descending aorta & is immediately inferior to the celiac trunk is the _____ artery

superior mesenteric

Angiotensin II causes:

vasoconstriction, decrease urine formation, and increased thirst.

Atrial natriuretic peptide stimulates:

vasodilation, increased urine output, and therefore decreased blood pressure.
