In the exchange of materials—the metabolism of food and oxygen, and the removal of waste—which goes on between the living tissues and the blood, the capillaries have an important part. Despite the recognition of this fact it cannot be said that the condition of the blood in the capillary...
The heart is a pump that provides the force needed to move blood around your entire body and return it back to the heart. Blood moves around your body through a series of blood vessels, called arteries, veins and capillaries.

Blood pressure is caused by the beating of the heart, as the heart contract and forces blood out into the arteries they stretch to take in the new blood volume and blood pressure rises. As blood moves away from the heart and into arterioles and capillaries the blood pressure drops....

Controlled hypotension in neurosurgical practice has been used for decades, the aims being 1) to decrease blood loss during surgery, 2) to provide a dry surgical field and 3) to diminish the risk of intraoperative aneurysm rupture. The benefits of contro
The dermal vessels of men who express a familial predisposition to high BP exhibit increased minimum resistance and capillary rarefaction. Defective angiogenesis may be an etiological component in the inheritance of high BP. 展开 关键词: Humans Capillaries Blood Pressure Vascular Resistance Vasodilation ...
