Explanation

An arterial hyperemia is a typical form of violation of the local circulation, characterized by an increase in the blood supply of the organ or tissue due to increased blood flow through the arterial vessels (aorta, arterioles, arteries, and arterial capillaries). The affected tissue is pink or red in appearance and warm to the touch. In venous hyperemia (congestion), it's cold to the touch.
