100

•carry blood away from heart

arteries

100

•The force per unit area exerted on a vessel

blood pressure

100

blood flows into what atrium from the superior and inferior vena cava? 

right atrium 

100

Circulatory shock

•Any condition where blood vessels are inadequately filled

100

Hypovolemic shock

•result of large scale blood or fluid loss

•Hemorrhage, severe vomiting or diarrhea, extensive burns

200

veins 

•return blood to the heart

200

120 is a normal bp for 

systolic 

200

The QRS complex is: 

ventricular depolarization 

200

vascular shock 

•blood volume normal, but circulation reduced – result of extreme vasodilation

•Common cause – anaphylaxis or sepsis

200

•Angiotensin II – vasoconstrictor which increases blood pressure (ACE inhibitors are a common hypertension drug that prevent this hormone) would be an example of what kind of circulation control? neural, hormonal, or local 

hormonal 
300

– smallest vessels – exchange of gasses, nutrients, etc between blood and tissues

capillaries 

300

•Low blood pressure

•Below 90/60 mm Hg

hypotension 

300

The SA node is the cardiac rhythm maker. T/F

true

300

cardiogenic shock 

•heart can’t sustain adequate circulation, result of myocardial damage

300

prevent back flow of blood in veins

Venous valves

400

•relaxes smooth muscle, increases diameter

vasodilation 

400

hypertension 

•Chronically elevated blood pressure

•Above 140 mm Hg systolic or above 90 mm Hg diastolic

400

The pulmonary arteries are unique how? 

only arteries that bring blood away from heart 

400

•Accumulation of excess fluid in tissues

edema 

400

three controls of circulation 

hormonal local and neural 

500

Vasoconstriction

contracts smooth muscle, decrease diameter

500

diastolic blood pressure

during heart relaxation, vessel collapses again, 80 bpm 

500

The L ventricle is bigger because? 

it pumps blood to the whole body 

500

•Leaky vein valves

•Causes dilated, twisted veins

•Heredity, obesity, pregnancy, prolonged standing in one position can contribute

•Can lead to blood clots and swelling

varicose veins 

500

•Walls of arteries become thicker

•Causes hypertension

•Endothelium (inner lining of arteries) injured

atherosclerosis
