In addition to the myoglobinuria, two other mechanisms contribute to kidney impairment: low blood pressure leads to constriction of the blood vessels and therefore a relative lack of blood flow to the kidney, and finally uric acid may form crystals in the tubules of the kidneys, causing obstruction.
The increased acid concentration allows the iron from the aggregate protein to be released into the surrounding renal tissue. [13] Iron then strips away molecular bonds of the surrounding tissue which eventually will lead to kidney failure if the tissue damage is too great.

Kidney ischemia is a loss of blood flow to the kidney cells. Several physical symptoms include shrinkage of one or both kidneys, [19] renovascular hypertension, [20] acute renal failure, [19] progressive azotemia, [19] and acute pulmonary edema. [19] It is a disease with high mortality rate and high morbidity. [21]
Below are several examples of differing types of local blood flow regulation by specific organ type or organ system. In each case, there is a specific type of intrinsic regulation occurring in order to maintain or alter blood flow to that given organ alone, instead of creating a systemic change that would affect the entire body.
Many small blood vessels and capillaries sit dormant until you get your heart rate up during exercise, and nitric oxide enables blood to flow to these areas to allow your muscles to work, hence ...
During exercise increased flow to the working muscles is often balanced by reduced flow to other tissues, such as kidneys, spleen, and liver. [5] Blood flow to the muscles is lower in cold water, but exercise keeps the muscle warm and flow elevated even when the skin is chilled. Blood flow to fat normally increases during exercise, but this is ...
A study review published in Frontiers in Nutrition showed that people who consumed beetroot juice daily for anywhere from three to 60 days reduced their systolic blood pressure by five more points ...
Ischemia, meaning insufficient blood flow to a tissue, can also result in hypoxia in the affected tissues. This is called 'ischemic hypoxia'. Ischemia can be caused by an embolism, a heart attack that decreases overall blood flow, trauma to a tissue that results in damage reducing perfusion, and a variety of other causes.
