Arterial Function
Understanding Arterial Function
The Arteries transport blood rich in oxygen from the heart to the body under pressure equal to the Arterial Pressure measured by a blood pressure monitor. Arteries have three layers:
Inner Layer
An inner layer.
Middle Layer
A middle layer of muscles.
Outer Layer
An outer layer of connective tissue.
Ischemia
Ischemia is the reduction of arterial supply where the arteries that provide blood to a region of the body do not function adequately, resulting in decreased arterial blood and thus decreasing both oxygen and energy in that specific area.
The symptoms experienced by the patient are due to the dysfunction of this area and are more intense as the amount of blood reaching the tissues decreases. The damage caused by the lack of blood to the tissues of that specific area can be permanent or not, depending on the sensitivity of each area to oxygen deprivation (the nervous tissue, and more specifically that of the brain, is the most sensitive) as well as the duration of blood (oxygen) deprivation in that specific area.
Symptoms
The symptoms are more intense as the amount of blood reaching the tissues decreases and are due to the dysfunction of that specific area.
Tissue Sensitivity
The most sensitive tissue is the nervous tissue, and more specifically that of the brain. The damage depends on the duration of oxygen deprivation.
