Circulatory Lab Quiz

Front 1

arteries

Back 1

leave the heart

aorta and pulmonary

Front 2

veins

Back 2

enter the heart

superior vena cava
inferior vena cava
pulmonary veins

Front 3

umbilical cord

Back 3

umbilical arteries and a single vein

Front 4

leucocytes
know how to draw them

Back 4

neutrophils, lymphocytes, monocytes, eosinophils, basophils

Front 5

how many chambers does the heart have? what are they?

Back 5

four
two atria and ventricles
each atrium and ventricle is separated via an AV valve

Front 6

what chamber is on the right?
is its blood oxygenated or deoxygenated?

Back 6

tricuspid

deoxygenated

Front 7

what chamber is on the left?
is its blood oxygenated or deoxygenated?

Back 7

bicuspid

oxygenated

Front 8

what are heart sounds caused by?

Back 8

blood flowing through the AV valves and the closing of the semilunar valves

Front 9

are pulse rate and heart beat the same?

Back 9

yes

Front 10

what two numbers is blood pressure recorded as?

Back 10

systolic pressure: the contraction of the ventricles

diastolic pressure: pressure in the arteries as the ventricles relax

Front 11

EKG

Back 11

electrocardiogram: a recording of the electrical impulses detected at the body's surface

Front 12

what is the first sound heard when determining blood pressure?

Back 12

the blood beginning to flow through the brachial artery

Front 13

SA node

Back 13

sinoatrial node

a bundle of nervous cells known as the pacemaker of the heart

the contractions are electrical impulses

Front 14

where is the SA node located

Back 14

in the right atrium and cause both the left and right atria to contract

Front 15

AV node

Back 15

sends impulses to the Bundle of His, a bundle of conducting fibers, then to the ventricles which causes them to contract

Front 16

where is the AV node located?

Back 16

the right atrium

Front 17

how long does each heart beat last?

Back 17

.8 of a second

Front 18

aorta

Back 18

leaves the left ventricle and carries oxygenated blood

Front 19

coronary

aka cardiac artery

Back 19

first branch of the aorta

supplies the cardiac muscle tissue cells of the heart with oxygen right blood

Front 20

pulmonary artery

Back 20

leaves the right ventricle of the heart and carries deoxygenated blood to the lungs where the hemoglobin the red blood cells combines with the oxygen.

the oxygenated blood is then carried back to the left atrium by the pulmonary veins

Front 21

difference between fetus pulmonary artery and adult

Back 21

in fetus the pulmonary artery doesnt carry blood to the lungs because the lungs arent functional.

the pulmonary artery is connected to aorta via the arterial ducts or ductus arteriosus

Front 22

when does the ductus arteriosus close?

Back 22

when baby is born and begins to breath through its lungs

Front 23

what are the veins that carry deoxygenated blood back to the right atrium?

Back 23

superior vena cava
inferior vena cava

Front 24

where does the superior vena cava carry blood from?

Back 24

should and head area

Front 25

where does the inferior vena cava carry blood from?

Back 25

pelvic and abdominal area

Front 26

what do the subclavian arteries do?

Back 26

carry blood to the shoulder and forelimb area

Front 27

what do the illiac arteries do?

Back 27

carry blood to the legs or hindlimb area

Front 28

what do the renal arteries do?

Back 28

carry blood to the kidneys

Front 29

whats a difference btw fetal or and newborn circulation?

Back 29

umbilical arteries carry deoxygenated blood from fetus to mother's placenta and an umbilical vein carries oxygenated blood back to the heart of the fetus. (these blood vessels replace the pulmonary artery and veins in a newborn)

Front 30

neutrophils
(a leococyte)

Back 30

-phagocytic
-can leave the blood stream, squeezing btw the capillary walls and engulf bacteria at the site of an infection
-they have an amoeboid action

Front 31

monocytes

Back 31

same action as a neutrophil except they leave the blood stream only in chronic infections and when neutrophils cannon combat the invading organisms

Front 32

lymphocytes

Back 32

product antiobiotics which aid your immune system

Front 33

eosinophils

Back 33

-produce antihistamine in allergic responses
-have bright red granules in they cytoplasm and are quite numerous when the body is reacting to allergens and histamine is produced

Front 34

basophils

Back 34

-produce an anticoagulant called Herapin
-normally found in blood, which prevents the blood from clotting wtihin the blood vessels

Front 35

what kind of muscle is the heart?

Back 35

cardiac muscle

Front 36

what gets oxygenated blood first? the heart or the brain?

Back 36

heart

Front 37

what happens in capillaries

Back 37

an exchange of CO2 and oxygen

where veins and arteries connect

Front 38

what are the five major vessels that leave the heart

Back 38

superior vena cava
inferior vena cava
pulmonary artery
pulmonary vein
aorta

Front 39

how does the fetal circulation differ from that in the adult pig?

Back 39

umbilical cord
lungs dont work (ductus arteriosus)
