Precapillary sphincters, found at the entrance of capillary beds, regulate blood flow by constricting or relaxing. When these sphincters are closed, blood flow is redirected to other tissues, often in response to factors like low oxygen levels or high metabolic demand. Conversely, they open in response to increased tissue activity or signals such as elevated carbon dioxide levels, allowing for enhanced nutrient and gas exchange in active areas. This dynamic regulation helps maintain homeostasis and efficient circulation throughout the body.
