Web1 de ene. de 2024 · Here regulation of HR and BP is presented for both static and dynamic exercise in humans. The events taking place during the transition from rest to exercise are addressed, and the dramatic acute changes in cardiovascular control that underpin these changes are described. WebRegulation of renal blood flow is important to maintaining a stable glomerular filtration rate (GFR) despite changes in systemic blood pressure (within about 80-180 mmHg). In a mechanism called tubuloglomerular feedback , the kidney changes its own blood flow in response to changes in sodium concentration.
