What best describes ischemic hypoxia?

Ischemic hypoxia is specifically characterized by insufficient blood circulation leading to inadequate oxygen supply to tissues. This condition arises when blood flow is reduced or obstructed, which can occur due to factors like blood clots, heart failure, or other cardiovascular issues. While anemia, high altitude, and respiratory arrest can all contribute to decreased oxygen levels in the body, they do not directly describe the condition of ischemic hypoxia. In ischemic hypoxia, the primary issue is the impaired delivery of oxygen-rich blood to tissues, making option related to insufficient blood circulation the most accurate description of this specific type of hypoxia.
