Normal blood vessel (left) vs. vasodilation (right) Vasodilation, also known as vasorelaxation, is the widening of blood vessels. [1] It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins, large arteries, and smaller arterioles. [2]
High blood pressure Stage 1 is defined as 130-139 over 80-89 mm Hg. The best ways to reduce high blood pressure—and your risk for its consequences like heart attacks and stroke—is to eat a ...
Substances called vasoconstrictors can reduce the size of blood vessels, thereby increasing blood pressure. Vasodilators (such as nitroglycerin) increase the size of blood vessels, thereby decreasing arterial pressure. If the blood viscosity increases (gets thicker), the result is an increase in arterial pressure.
Over 100 reported cases of malignant transformation have been reported at a rate reported as 0.4% to 1% [15] [dubious – discuss] Severe bleeding from minor trauma, of particular concern in the elderly [11] Blood clotting within affected veins, termed superficial thrombophlebitis. [11]
Over time, high blood pressure can cause damage to the arteries that can lead to health conditions including stroke, heart disease, kidney problems and dementia. There are multiple risk factors ...
“Studies have found that including unsaturated fats in your diet not only positively influences blood cholesterol and risk of heart disease, but also body fat distribution,” she says. 2. Full ...
Blood viscosity is a measure of the resistance of blood to flow. It can also be described as the thickness and stickiness of blood. This biophysical property makes it a critical determinant of friction against the vessel walls, the rate of venous return, the work required for the heart to pump blood, and how much oxygen is transported to tissues and organs.
Exercise is one of the best ways to combat some of the most common perimenopause symptoms, including mood changes, weight gain, body aches and fatigue. Even during the busy holiday season, try to ...
