Circulation

Front 1

What are the two parts of the Circulatory system?

Back 1

Pulmonary, Systemic

Front 2

Features of cardiac muscle

Back 2

cardiocytes, striated, intercalated discs, involuntary

Front 3

Three parts of the Pericardium

Back 3

Pericardial sac=parietal pericardium-tough outer layer

Visceral pericardium=epicardium-inner thin serous layer

Pericardial cavity-contains pericardial fluid

Epicardium=visceral pericardium

Front 4

Heart Wall Layers

Back 4

EPICARDIUM=Visceral pericardium-outer

simple squamous epith/connective tissue

MYOCARDIUM-middle thickest layer, muscle spirals, forceful contraction

ENDOCARDIUM-inner lining of the heart chambers, simple squamous, covers valves; continuous with blood vessel lining

Front 5

Mediastinum

Back 5

space in which the heart lies

Front 6

What are the three vessels that empty into the right atrium?

Back 6

Superior Vena Cava

Inferior Vena Cava

Coronary sinus

Front 7

What is systole?

Back 7

When the heart contracts

Front 8

What is diastole?

Back 8

When the heart relaxes

Front 9

What artery do you use to take a blood pressure?

Back 9

Brachial

Front 10

What ventricle is the largest?

Back 10

Left

Front 11

Where are the chordae tendinae found? What do they prevent?

Back 11

ventricles, regurge of blood into the atrium

Front 12

What is the purpose of the papillary muscles?

Back 12

to anchor the chordae tendinae

Front 13

Where does incoming deoxygenated blood return to?

Back 13

Right Atrium

Front 14

What vessels supply blood to the heart?

Back 14

Coronary Arteries

Front 15

The right coronary artery supplies blood to what portion of the heart? and where is it located?

Back 15

Blood supply to the SA and AV nodes; posterior

Front 16

How does the Left Coronary artery provide blood to the heart? Where is it located on the heart?

Back 16

It splits into two branches; supplies blood to the left ventricle; anterior

Front 17

What is anastomoses?

Back 17

When one vessel is blocked it has the ability to redirect

Front 18

What do the Coronary Sinus' do?

Back 18

Bring de oxygenated blood from the heart to the Right Atrium

Front 19

What are the three layers of vessel walls?

Back 19

Tunica externa

Tunica media

Tunica interna

Front 20

What layer of the vessel would plaque form?

Back 20

Tunica media

Front 21

vaso vasorum

Back 21

tiny blood vessels that com from the lumen to carry blood to and from walls of vessels.

Front 22

What is the endothelium?

Back 22

Layer next to the lumen

Front 23

What layer of the vessel is the vasa vasorum located?

Back 23

Tunica externa

Front 24

What layer of the vessel would you find smooth muscle?

Back 24

Tunica media

Front 25

What is the junction called where the aorta punctures the diaphragm?

Back 25

aortic hiatus

Front 26

What is a capillary bed?

Back 26

network of capillaries

Front 27

What happens before final venous drainage?

Back 27

blood from one capillary bed travels via vein to another capillary bed. (two capillary beds lie between arterial supply and venous drainage)

Front 28

What vessels lie within the carotid sheath?

Back 28

Interior jugular

common carotid

vagus nerve

Front 29

Most lateral superficial vein in the arm?

Back 29

cephalic

Front 30

Most proximal superficial vein in the arm?

Back 30

basilic

Front 31

Most common place for blood draw?

Back 31

median cubital (anticubital fossa)

Front 32

pectinate muscles are found where?

Back 32

Atrium
