Cerebral circulation is the movement of blood through the network of blood vessels supplying the brain.

The goal of all of these is separating the pulmonary and the systemic circulation.

This is done to treat or prevent problems with distal circulation, or ventilation.

The amount of blood that the cerebral circulation carries is known as cerebral blood flow.

The brain's blood circulation is capable of disposing of excess heat by increasing local blood flow.

They are part of the Circle of Willis, which provides backup circulation to the brain.

Improving the circulation is important in treating skin ulcers, and patients are consequently usually recommended to exercise, stop smoking, and lose weight.

When wrapped around limbs and fins, it can cause circulation loss and amputation, especially as the animal grows.

When released into a person s circulatory system, hemoglobin in these higher oxidation states eventually self destructs, damaging molecules in surrounding tissue.

Neurohormones, released by neurosecretory cells, also have an effect on many brain regions via the circulatory system.

The leading cause of death (mortality) in 2002 was diseases of the circulatory system, with 53.1 per cent of the death rate.

Vascular grafting is the use of transplanted or prosthetic blood vessels in surgical procedures.

The intracellular components of the RBCs are released into the circulating blood and into tissues, leading to some of the characteristic symptoms of this condition.

The smallest blood vessels are called capillaries we've got 19 billion of them in our bodies.

Reticulocytes develop and mature in the bone marrow and then circulate for about a day in the blood stream before developing into mature red blood cells.

In developing countries, the major causes of death traditionally were infectious and parasitic diseases, whereas in industrialized countries, the major killers were diseases of the circulatory system.

The first pass effect (also known as first pass metabolism or presystemic metabolism) is a phenomenon of drug metabolism whereby the concentration of a drug is greatly reduced before it reaches the systemic circulation.

They are removed by the spleen, which leads to low platelet counts.

During the next day, its eye became obscured after the mountains of New Caledonia affected Rewa's circulation by creating a hot and dry Foehn wind.

(g) Haematology identification of how the human blood circulation system adapts to space flight and development of diagnostic criteria to evaluate the state of the human organism under extreme conditions

There is also irregular fibrosis of the blood vessels due to chronic vasculitis, leading to sometimes massive intimal fibrosis (fibrosis of the inner section of the blood vessels).

a) The bloody denouement of the protests on Tiananmen Square.

Some recent therapeutic possibilities include the co infusion of haptoglobin with hemoglobin in circulation or with vitamin C additives that hold promising implications for the development of safe and effective blood substitutes.

We get most of these blood vessels when we're actually still in the womb, And what that means is that as adults, blood vessels don't normally grow.

When blood vessels constrict, the flow of blood is restricted or decreased, thus retaining body heat or increasing vascular resistance.

Most of the illnesses in 2001 were circulatory system disorders, at 26.2 per cent, then respiratory tract disorders, at 18.3 per cent, followed by bone and muscular disorders, at 9 per cent.

He actually devised some of the same technologies used today for suturing blood vessels, and some of the blood vessel grafts we use today were actually designed by Alexis.

She has always had problems with the circulation in her hands and feet.

Groups of blood vessels form at the entrance of the dental papilla.

The new lung is then placed and the blood vessels reattached.

Nitroglycerine addresses the risk of circulatory collapse. In economic terms, that is what was needed following the 2008 global financial crisis.

The leading diseases in 2001 are circulatory diseases, with a structural index of 26.2 per cent, diseases of the respiratory system, 18.3 per cent and bone and muscular diseases, 9 per cent, etc.

They're basically fouling up Earth's respiratory and circulatory systems.

The new process involved injecting arsenic into the blood vessels of the corpse.

There are three major types of blood vessels the arteries, which carry the blood away from the heart the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues and the veins, which carry blood from the capillaries back toward the heart.

He also had a brain aneurysm which causes hallucinations.

While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system.

Reference ranges for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples.

It is evident that diseases of circulatory systems are first with 8,300 per 100,000 persons, while the rate of bone and muscular diseases is also increasing, followed by the diseases of digestive systems and mental and behaviour disorders.

It s not so much psychological, it s vascular, and nicotine makes your arteries constrict.

And, like a tumor, fat grows when blood vessels grow.

We did not know that you possess this rare group of blood.

Platelets are thought to speed the healing process.

He suggested that tumors emit a substance called tumor angiogenesis factor, which causes surrounding blood vessels to grow toward it, supplying nutrition and removing waste.
