Hyperemia is defined as which of the following?

Explanation:
Hyperemia means increased blood flow to a region, typically from dilation of the small arteries and arterioles. This rise in flow brings more oxygen and nutrients to the tissue and is usually visible as redness and warmth. It commonly occurs with inflammation or during physical activity when the tissue needs more blood. It’s different from reduced blood flow (ischemia) or from edema due to lymphatic blockage (lymphedema) or vessel constriction (vasoconstriction), all of which involve less blood flow or fluid buildup rather than an increase.
