Which of these local chemical factors will NOT cause vasodilation of arterioles

Question

Quizplus · Accepted Answer

Decreased K⁺ does not cause vasodilation; instead, it can lead to hyperpolarization and potentially reduce cellular excitability. Increased CO₂, increased acid, and decreased O₂ are all factors that can lead to vasodilation as they are indicators of increased metabolic activity or hypoxia, signaling the need for increased blood flow.
