base of aorta

...

You can expect children to have Lower blood pressure than adults on average because

their blood vessels length is less

A temporary loss of consciousness due to a decrease in blood flow to the brain is termed

fainting

Each of the following will lead to a decrease in blood pressure except

release of renin

Fear can result in

increased stimulation of the cardioaccelerator center by higher brain centers.

Elevated levels of the the natriuretic peptide hormones ANP and BNP will produce increased

salt and water loss through the kidneys

Which of the following conditions is least likely to lead to rein release ?

Hypertension

Baroreceptors are located in the:

carotid sinus

popliteal

The vessels that receives blood from the head , neck , chest , shoulder, and arms is the

Superior Ven Cava

What are the layers of the blood vessels from outside to inside?

tunica externa, tunica media, tunica interna

What is the primary reason for cardiovascular diseases affects older women and not younger women ?

Older women lack estrogen

A genetic condition that leads to the inability to absorb and recycle cholesterol in the liver ?

Familial hypercholesterolemia

Which of the following is not a commonly palpable arterial pressure point ?

Femoral

Which vessel has only the tunica intima layer ?

Capillaries

Resistance is a force that

decreases blood flow

As blood travels from arteries to veins,

pressure drops

Blood pressure is determined by

estimating the pressure needed to close off an artery with an external pressure cuff.

In what vessels is blood pressure the highest?

Artery

Blood pressure increases with all the following expect increased

Parasympathetic innervation

The main concept of peripheral resistance occurs in the

Arteriole

Clinically, the term blood pressure usually refers to

arterial pressure

Average over few hearts beats venous return is ____cardiac output

Somewhat lower than

Blood pressure is lowest in the

veins

If blood pressure doubled, the blood flow through a vessel would be

doubled

Compared to arteries, veins

have thinner walls

Capillaries that have a complete lining are called

continuous capillaries

The smallest arteries branches are called

arterioles

The layer between the tunica media and the tunica externa in a large artery is the

external elastic membrane

Which of the following layers of vessels contains collagen with scatted bands of elastic fibers ?

Tunica. Externa

After blood leaves the capillaries, it enters the

venules

Which layer of a blood vessel contains concentric sheets of smooth muscle tissue?

tunica media

The large vessels that return blood to the heart are called

veins

In arteries, the thick layer of elastic fibers associated with the tunica intima is called the

internal elastic membrane

Which of the following is the innermost layer of a blood vessels ?

tunica interna

Venoconstriction ________ the amount of blood within the venous system, which ________ the volume in the arterial and capillary systems.

reduces; increases

Venous vales are responsible for

Prevent blood from re entering a ventricle

Vena cave are the largest of what type of vessels?

Veins

Which of the following vessels change diameter most readily to local conditions or SNS stimulation?

Arteroles

Of the following which is an elastic artery?

subclavian

A sample of tissue displays many large flattened spaces lined by fenestrated endothelium. Blood moves slowly through these spaces. This tissue sample most likely came from the

liver

These vessels may be continuous or fenestrated.

capillaries

What structure do RBC's move thought single -file ?

Capillaries

Capillaries with a perforated lining are called

fenestrated capillaries

Exchange between a blood vessel and the cells that surround it can occur only in

capillaries

Which kind of vessel is also called a resistance vessel?

arteriole

Blood flow through a capillary is controlled by the

precapillary sphincter

The common iliac artery is an example of which type of artery ?

elastic

Venoconstriction reduces the diameter of which vessel?

vein

The brachial and femoral arteries are examples of which type of artery?

muscular

What vessels contain elastic fibers in the walls that are stretched during systole?

arteries

Which of the following is mostly likely to result from an aneurysm in the brain artery ?

Stroke

arteriosclerosis can lead to all the following except

diabetes

Which of the following are the smallest venous vessels?

venules

Blood moves forward through veins because of all of the following, exctept

Pumping by the smooth muscle in the wall of the vein

What is the correct order for the sequence of blood vessels that blood would travel in the systemic circuit starting at the aorta ?

4, 7, 2, 3, 1, 5, 6

The main concept of peripheral resistance occur in the

Arterioles

Multiple arteries joined in order to serve a single capillary network are called

collaterals

The direct interconnected of two arteries is called an arterial

Anastomosis

In the condition know as ____ the wall of an artery becomes thicker and stiffer
