BMS100 PHGY STUDYSET EXAM
cardiovascular vital signs - Answer - blood pressure 90/60 - 140/90
- heart rate: 60-100 bpm at rest
- repiration rate 12-20 bpm
- major pulses
cardiovascular system components (4) - Answer - heart: L oxygenated
- arteries: flexible muscular vessles taking away from heart
- capillaries: 1 cell thick for gas and nutrient exchange
- veins: take blood back to heart without back flow
pulmonary circulation def - Answer - deoxydenated blood from right side of heart to lung
- moderate pressure
- pulmonary artery -> pulmonary capillaries -> pulmonary vein
systemic circulation - Answer - oxygenated blood from left side of heart to body
- high pressure
- systemic artery -> systemic capillaries -> systemic vein
parallel system - Answer - blood from digestive capillaries go to liver for detox via portal
vein
superior and inferior vena cava - Answer - vein that bring deoxygenated blood from
head and body back to heart
heart phases - Answer - diastole: relax, low pressure and draw blood from veins
- systole: contraction, pressure and eject blood into arteries
arteries pressure - Answer - have internal and external elastic vesicles
- during disatole potential energy is stored in elastics to pressuer do not drop below 80
ish
, arterioles - Answer - Small arteries that deliver blood to capillaries
- constrict and dialate and have sphincter to control flow
heart chambers and actions - Answer - L atrium systole: from P vein to ventricle adding
5% volume
- L ventricle systole: from L atrium to aorta
- R atrium: from vena cava to R ventricle
- R ventricle: to pulmonary arterie
heart cycle - Answer - ventricular diastole: atrium and ventricle refelling
- atrial systole: atrium -> ventricles
- ventricular systole: contraction and ejection to arteries
isovolumetric relaxation/contraction - Answer contraction: ventricular systole when all
four valves are closed
relaxation: all four valves are closed and only atrium are filling
inspiration - Answer - more volume -> less pressure -> air comes in
- diaphragm contracts down
- external intercostal muscles contract out
expiration - Answer - less volume -> more pressure -> air out
- diaphragm relaxese up
- external intercostal muscles relax in
stoke volume - Answer volume of blood pumped with each contraction
- SV x heart rate = flow
baroreceptor - Answer - pressure sensors
- carotid sinous and aortic arch (under clavical)
- lower pressure -> message to brainstem -> sympathetic nervous system -> epinephrine
-> constriction and heart rate
cheomoreceptors - Answer - gas sensors for CO2 O2 and pH
- peripheral: same location as baroreceptor
- central: in the brain
