what is the significance of the viscosity of blood to health?

Blood viscosity (that increases with increasing HCT) is considered as an important determinant for oxygen transport and delivery. Increased number of erythrocytes can enhance platelet adhesion and endothelial deposition and could increase risk of thrombotic complications.

Viscosity depends strongly on temperature. In liquids it usually decreases with increasing temperature, whereas in gases viscosity increases with increasing temperature.

Viscosity rating is a measure of the oil's resistance to flow or thickness, and is the single most important characteristic of hydraulic oil. The viscosity index number indicates the extent of thickness, or resistance to flow, with temperature changes.

Some patients with anemia have low hematocrits, and therefore reduced blood viscosities. Another important factor that influences blood viscosity is temperature. Just like molasses, when blood gets cold, it becomes "thicker" and flows more slowly.

High hemoglobin levels could be indicative of the rare blood disease, polycythemia. It causes the body to make too many red blood cells, causing the blood to be thicker than usual. This can lead to clots, heart attacks, and strokes. It is a serious lifelong condition that can be fatal if it is not treated.

Blood brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.

Thus, decrease in hematocrit could possibly account for the faster fall of red blood cells and hence increased ESR observed during menstruation (Everett et al., 1978). Increase ESR during the menstrual phase could possibly explain decrease blood viscosity observed at this phase (Cheesbrough, 2000).

The three factors that contribute to blood pressure are resistance, blood viscosity, and blood vessel diameter.

Getting routine blood work is essential for diagnosing a number of diseases and conditions, as well as checking blood glucose and cholesterol levels. Although some diseases and medical problems can't be diagnosed via blood work, knowing your numbers can help you and your doctor learn more about your health.

Absolute viscosity - coefficient of absolute viscosity - is a measure of internal resistance. Dynamic (absolute) viscosity is the tangential force per unit area required to move one horizontal plane with respect to an other plane - at an unit velocity - when maintaining an unit distance apart in the fluid.

Viscosity and Specific Gravity of Liquids Viscosity - Property of a liquid that resists any force tending to produce flow. ... Specific Gravity - Direct ratio of any liquid's weight to the weight of water at 62 degrees F. Water at 62 degrees F weighs 8.33 pounds per gallon and is designated 1.0 sp.

The most important factor affecting BP is the diameter of the blood vessel, but vessel length and the viscosity of the blood are also factors. In addition, the greater the blood volume in the vessels, the greater the blood pressure.

Normal level In pascal-seconds (Pa·s), the viscosity of blood at 37 °C is normally 3 × 10−3 to 4 × 10−3, respectively 3 - 4 centipoise (cP) in the centimetre gram second system of units. Blood viscosity can be measured by viscometers capable of measurements at various shear rates, such as a rotational viscometer.

Compared to female blood, male blood had higher viscosity and RBC aggregation and lower RBC deformability. Oxygen Delivery Index, calculated as a ratio of hematocrit to blood viscosity, was found to be significantly lower in male blood.

Its most important function is vasodilation, meaning it relaxes the inner muscles of the blood vessels, causing them to widen and increase circulation. Nitric oxide production is essential for overall health because it allows blood, nutrients and oxygen to travel to every part of your body effectively and efficiently.

Certain measurements using viscosity can be a precisel to the average molecular size of a polymer sample in solution. The impact of a given amount of a polymer on the viscosity of a solvent is the effect which Einstein pointed out. The "inherent viscosity" is the fundamental determination made using this effect.

Viscosity is a fundamental material property when studying fluid flow for any application. ... Dynamic viscosity (also known as absolute viscosity) is the measurement of the fluid's internal resistance to flow while kinematic viscosity refers to the ratio of dynamic viscosity to density.
