OVERVIEW OF CIRCULATION Flashcards
one pump propels blood through the lungs for exchange of oxygen and carbon dioxide
pulmonary circulation
pump that propels blood to all other tissues of the body
systemic circulation
in the __________ arteries, frictional resistance is relatively small, and pressures are only slightly less than those in the aorta
large arteries
the resistance reaches a maximal level in the ______, which are sometimes referred to as the stopcocks of the vascular system
arterioles
the total cross sectional area of the _______ is very large despite the fact that the cross-sectional area of each capillary is less than that of the arteriole
capillary bed
pressure within these vessels progressively ________ until the blood reaches the right atrium
decreases
in the patient with ____________(Grave’s disease), basal metabolism is elevated and often associated with arteriolar vasodilation
hyperthyroidism
velocity of blood flow is _________ related to the cross-sectional area at any point along the vascular system
inversely related
