The term «vascular recruitment» or «capillary recruitment» usually refers to the increase in the number perfused capillaries in skeletal muscle in response to a stimulus. The most important stimulus in humans is regular exercise. Vascular recruitment in skeletal muscle is thought to enhance the capillary … See more Vascular recruitment is the increase in the number of perfused capillaries in response to a stimulus. I.e., the more you exercise regularly, the more oxygen can reach your muscles. Vascular … See more Vascular recruitment in the brain is thought to lead to new capillaries and increase the cerebral blood flow. See more Vascular recruitment in the lung (i.e., in the pulmonary microcirculation) may be noteworthy to healthcare professionals in emergency medicine, … See more The existence of vascular recruitment in response to a stimulus has been disputed by some researchers. However, most researchers accept that vascular recruitment exists. See more WebWe have also observed pulmonary capillary recruitment in normal humans during exercise (unpublished data). Recruitment is a normal physiological process, and it is impaired in many types of PH. As we move forward in our understanding of exercise PH and its physiology, precise definitions and semantics will be critical. Footnotes

WebAug 22, 2013 · The results imply that capillary recruitment, as observed in the hamster cremaster preparations, can occur as a consequence of local control of arteriolar tone and the resulting nonuniform changes in red blood cell fluxes, and provide an explanation for observations of sequential recruitment of individual capillaries in response to modulation ... WebOct 30, 2024 · Importantly, the capillary regions that constricted were invested with pericytes and capillary de-recruitment was prevented in a transgenic mouse model featuring partial pericyte depletion. This was the first direct in vivo visualization of hyperemia-induced capillary de-recruitment distal to an arterial stenosis and the results … knocks me off my feet original singer
