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.
When blood leaves a ruptured blood vessel, the red blood cell dies, and the hemoglobin of the cell is released into the extracellular space. Phagocytic cells (of the mononuclear phagocyte system) called macrophages engulf (phagocytose) the hemoglobin to degrade it, producing hemosiderin and biliverdin. Excessive systemic accumulations of ...

Edible thickeners are commonly used to thicken sauces , soups , and puddings without altering their taste; thickeners are also used in paints , inks , explosives , and cosmetics .
Polycythemia in newborns is defined as hematocrit > 65%. Significant polycythemia can be associated with blood hyperviscosity, or thickening of the blood. Causes of neonatal polycythemia include: Hypoxia: Poor oxygen delivery (hypoxia) in utero resulting in compensatory increased production of red blood cells (erythropoeisis). Hypoxia can be ...
Bread Flour. Comparing bread flour versus all-purpose flour, the former has the highest protein content of the refined wheat flours, clocking in at up to 14 percent.
Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
“Too much visceral fat has been linked to high cholesterol, insulin resistance and high blood pressure, as well as increased risk for heart disease, stroke and type 2 diabetes.”
The donations were first reported by the Wall Street Journal. Amazon joins another tech giant, Meta Platforms, in donating to the Jan. 20 Trump inauguration. Meta will also give $1 million, a ...
