an excess of blood in an area or part of the body
P,S Hyperemia occurs when arterial and arteriolar dilatation produces an increased flow of blood into capillary beds. In other words, hyperemia is an active process. As would be expected, there is increased redness in the affected area. The arterial and arteriolar dilatation is brought about by sympathetic neurogenic mechanisms or the release of vasoactive substances. Cutaneous hyperemia occurs whenever excess body heat must be dissipated, such as in exercise and febrile states. Blushing is another example of hyperemia induced by neurogenic mechanisms. In veterinary medicine, the most common cause of hyperemia is that associated with vasoactive substances released in inflammatory processes.
Excessive presence of blood, usually arterial; and the resultant increase in heat and metabolic rate. Hyperemia can be a pathology, blowing out blood vessels and the like; used here to describe the chronic or subclinical condition of functional vascular excess and excitation.
Excess of blood in a body part.
Reddening caused by increased blood flow.
congestion of blood in a body part.
increased blood in an organ or other body part
increased blood flow to an area
Excess blood (engorgement) in a localized area.
Increased blood flow to a body part; enlargement of organ due to increase of blood; swelling. Ice therapy is usually the recommended treatment for swelling.
Increased volume of blood in an organ caused by increased arterial flow.
Increase in quantity of blood flowing through the body or part of the body characterized by heat, redness: Vasodilatation
Excessive amount of blood in a part due to overactivity of vaso-dilator neural units.
An increased amount of blood in a part with distention of blood vessels.
an excessive amount of blood forming in an area
An unusual amount of blood in a part, congestion.
The presence of an increased amount of blood in a part or organ.
Abnormally increased blood flow
Excess of blood (circulation) in any part of the body
Increased blood flow; may cause dental sensitivity to temperature and sweets; may precede an abscess
The presence of excess blood in a tissue area.
An excess of blood in an area or body part; usually indicated by red, flushed color or heat in the area.
An excess of blood in a part of the body
condition of increased blood accumulation in a portion of the body, due to inflammation, obstruction to blood flow, or local relaxation of arterioles
