Decreased tissue blood flow due to occlusion will result in metabolic vasodilators accumulating in the extracellular fluid. The arterioles will hence dilate but the occlusion will still prevent normal blood flow. The occlusion is then removed and decreased resistance will increase blood flow. As the vasodilators are washed away, the arterioles constrict, and the blood flow returns to normal.

What is reactive hyperemia?
Reactive hyperemia is the transient increase in blood flow that occurs after a temporary obstruction of blood supply to a tissue. When blood flow is restored, the affected area experiences a surge of blood, delivering oxygen and nutrients while helping to remove metabolic waste. This phenomenon is often observed after the release of a pressure applied to a limb or following ischemia. It plays a crucial role in tissue recovery and maintaining homeostasis.
What is the plural of hyperemia?
The noun 'hyperemia' is an uncountable noun, a word for a physical condition.

What is increased blood supply in part of the body?
Hyperemia
What is hyperemia of mucous membrane?
Hyperemia of the mucous membrane refers to an increased blood flow to the mucous lining of a specific area in the body. This can result in redness, swelling, and irritation of the mucous membrane due to increased blood supply. Hyperemia can be caused by various factors such as inflammation, infection, or irritation.
What is the difference between erythema and hyperaemia?
Erythema is the physical sign of redness of an ectodermal structure like skin or the exocervix. It is caused by Hyperemia, which is the presence of increased blood flow to a particular structure. Erythema is a physical sign, while Hyperemia is a physiologic process. Hyperemia can also occur in other parts of the body like in a myocardial infarct.
What can cause hyperemia?
Hyperemia can be caused byaldosterone hormone (which increases blood volume, therefore, icreases blood pressure). Either way by physical exercise -when someone is training,working out- which activates sympaticus and parasympaticus.
What is it abnormal focal hyperaemia?
Abnormal focal hyperemia refers to an increased blood flow to a specific localized area in the body. This can be a sign of inflammation, infection, or tissue damage in that particular region. It is important to identify the underlying cause of the abnormal hyperemia to determine the appropriate treatment.
What is vaginal hyperemia?
Vaginal hyperemia refers to an increased blood flow to the vaginal tissues, often resulting in swelling, redness, or a feeling of fullness in the area. This condition can occur due to various factors, including hormonal changes, arousal, or inflammation. While it is typically a normal physiological response, persistent hyperemia may indicate underlying issues that require medical attention.
What is reactive volt amps?
volt ampere reactive is the unit of reactive power.It is the power which does no useful work but is required to assist in performing work,such as setting up magnetic fields in motors and transformers.It is also called as imaginary power.It occurs in purely reactive circuit i.e. purely inductive or capacitive.The inductance absorbs the reactive power and capacitance injects the reactive power.In inductance,reactive power is utilised to develop the flux while in the capacitance,the reactive power's function is to store the charge.
The redness and heat of an inflamed area are due to a local hyperemia caused by?
chemicals released by the injured tissue cells and leukocytes cause the VASODILATION of the arterioles in the injured area and cause the local hyperemia to form accounting for the redness and heat.
What is hyperemia along the proximal tibial metadiaphysis?
Hyperemia is basically the increase of blood flow to a particular organ in the body. Therefore concerning an injury to the tibial metaphysis, excessive blood will migrate towards joints. It is also known to cause excessive bone growth.
