Blood Vessels Quiz (M3)

Front 1

Blood pressure is highest in _____.

Back 1

arteries

Front 2

Blood velocity is slowest in ____

Back 2

capillaries

Front 3

Most of the blood in the cardiovascular system is found in ____.

Back 3

veins

Front 4

Vasoconstriction of arteries will bring about an ____ in blood pressure.

Back 4

increase

Front 5

The circulatory shock as a result of a myocardial infarction.

Back 5

cardiogenic shock

Front 6

The circulatory shock that results from a bacterial infection.

Back 6

septic shock

Front 7

increases blood vessel diameter

Back 7

vasodilation

Front 8

What tissue makes up the below blood vessel tunics
tunica media
tunica interna
tunica externa

Back 8

tunica media - elastic fibers, smooth muscle

tunica interna - simple squamous epithelium

tunica externa - elastic and collagen fibers

Front 9

How would the below factors affect blood vessel resistance and blood pressure?
vasodilation of arteries
losing weight
an increase in a hematocrit
the valsalva maneuver
polycythemia

Back 9

vasodilation of arteries - BP decreases; blood flow increases

losing weight -

an increase in a hematocrit - raises velocity of blood, increases resistance to flow and makes the blood more difficult for heart to pump

the valsalva maneuver - increased viscocity of blood & increases BO

polycythemia - increases resistance & BP

Front 10

The pressure in the arteries when the heart is contracting.

Back 10

systolic pressure

Front 11

This pressure is the afterload.

Back 11

diastolic pressure

Front 12

3 differences between arteries and veins.

Back 12

1. veins have thinner walls
2. veins carry blood to heart/arteries carry blood away from heart
3. lumen of a vein is larger than artery

Front 13

2 mechanisms that occur to bring about decompensated (progressive) shock.

Back 13

1. depression of cardiac shock
2. depression of vasoconstriction

Front 14

When you stand up after lying down the increased demand due to gravity stiulates the baroceptors of _____ & _____ and results in increased ______ stimulation that results in _____; BP _____.

Back 14

arch of aorta
carotid sinus
sympathetic
vasoconstriction
increases

Front 15

2 mechanisms that help maintain normal BP during compensated shock.

Back 15

1. activation of renin-angiotensin-aldosterone system
2. secretion of ADH

Front 16

How do the below factors influence blood vessels?
histamine
angiotensin II
atrial natriuretic peptide
antidiuretic hormone
epinephrine

Back 16

histamine - vasodilator
angiotensin II - potent vasoconstrictor
atrial natriuretic peptide - causes vasodilation
antidiuretic hormone - vasoconstriction
epinephrine - vasoconstriction of arterioles, veins & vasodilation of arterioles in cardiac and skeletal muscle; constrict blood vessels

Front 17

This vein returns blood to the right atrium from the heart itself.

Back 17

coronary sinus

Front 18

This artery supplies blood to the liver and stomach.

Back 18

celiac artery

Front 19

This vein drains blood from the leg

Back 19

great saphenous vein

Front 20

This vein carries blood from the kidney

Back 20

renal vein

Front 21

This vessel carries deoxygenated blood to the lungs

Back 21

pulmonary arteries

Front 22

this artery supplies blood to the heart

Back 22

marginal artery

Front 23

this artery supplies blood to the small intestine

Back 23

superior mesenteric artery

Front 24

this vein drains blood from the forearm

Back 24

basilic vein

Front 25

this is the artery commonly used for blood pressure tests

Back 25

brachial artery

Front 26

this is the vein that carries blood carrying the products of digestion to the liver

Back 26

hepatic portal vein

Front 27

4 differences between the adult and fetal circulatory system.

Back 27

1. ductus arteriosus -> ligamentum arteriosum

2. foramen ovale -> fossa ovalis

3. ductus venosus -> ligamentum venosum

4. umbilical vein -> ligamentum teres

5. umbilical arteries -> medial umbilical ligaments

Front 28

What is a portal circulatory pathway?

Back 28

blood passes from one capillary network into another thru a portal vein.

Front 29

What is a regular circulatory pathway?

Back 29

blood passes from heart and then in sequence to the arteries, ,arterioles, capillaries, venules, veins and back to heart.

Front 30

Example of portal pathway & why setup the way it is?

Back 30

hepatic portal circulation.
so the capillaries of gastrointestine organs & spleen can deliver nutrient rich blood directly to liver via hepatic portal vein.
