Cardiovascular System — Flashcards

Capillary refill time becoming faster is typically indicative of a _____ compromise

In _____ hypoxia, blood flow is very low; so, more oxygen is extracted causing an increase in reduced hemoglobin cyanosis.

Thin-walled and delicate vessels like capillaries are less prone to rupture and this can be explained by _____

In normally flowing blood in venules, _____ cells are confined to a central axial column

Baroreceptors provide _____ feedback in responses to changes in blood pressure

The main site of peripheral vascular resistance is precapillary _____

Height of contraction in a preloaded muscle contraction is _____ than afterloaded muscle contraction

Effect of valvular diseases on PV loop:The pressure-volume curve is tall with steep slope in _____

The presence of hemoglobin in normal arterial blood increases its O2 concentration approximately by _____ times

Activation of chemosensitive vagal C fibers located in the cardiopulmonary region, causing bradycardia, hypotension, and apnea followed by rapid shallow breathing, is known as _____ reflex
