NCSF- cardiovascular
physiology with correct
question and answers
2025/2026
activities that require greater intra-abdominal pressure for spinal stability will cause contracting
muscles to compress arteries causing ? - correct answersperipheral resistance
alveoli - correct answersa tiny, thin walled, capillary-rich sac in the lungs where the exchange of
oxygen and carbon dioxide takes place
aorta - correct answersThe largest artery in the body; it conducts freshly oxygenated blood from
the heart to the tissues.
aortic valve - correct answersa heart valve that has 3 flaps which guards the passage from the
left ventricle to the aorta and prevents the backward flow of blood
approximately how much of the 4 grams of iron contained in humans is found attached to
hemoglobin? - correct answers66%
arterioles - correct answersare the smallest of the arteries
arteriosclerosis - correct answerschronic condition characterized by the thinking and Harding of
the arteries and the build up plaque on the arterial walls
, causes- obesity, smoking, high cholesterol, physical inactivity and hypertension all increase risk
at rest how many of the capillaries are open? - correct answers20-25%
atherosclerosis - correct answersa stage of arteriosclerosis in which arteries become clogged
atria - correct answersthe two upper chambers in the heart which receive blood from the veins
and push it into the ventricles
atrium - correct answerstop chamber of the heart
barorecptors - correct answersdetect BP; can send messages to the central nervous system(CNS)
to increase or decrease total peripheral resistance and CO ( cardiac output)
bicarbonate - correct answersa salt of carbonic acid in which one hydrogen atom has been
replaced
bicuspid valve - correct answersa valve of the heart
blood leaving the heart first enters the large arteries that branch repeatedly into ? - correct
answerssmaller arteries
blood pressure (BP) is measured by ? - correct answersbaroreceptors located in the aorta and
the cardioid arteries
BP is determined by? - correct answersCO(cardiac output) x PR( peripheral resistance= BP(blood
pressure)
