Why is human blood viscous fluid?
The viscosity of the blood is due to the internal friction between the flow. It incorporates the effects of the suspended particles present in the blood, inclusive of RBCs, WBCs, and platelets.
What determines the viscosity of blood?
Blood viscosity is determined by plasma viscosity, hematocrit (volume fraction of red blood cell, which constitute 99.9\% of the cellular elements) and mechanical properties of red blood cells.
What happens when human blood is acidic?
The affinity that hemoglobin has for oxygen is decreased when the pH of the solution is decreased. So the oxygen carrying capacity of the hemoglobin will decrease if human blood becomes acidic.
What is the amount of blood in human body?
Children: The average 80-pound child will have about 2,650 mL of blood in their body, or 0.7 gallons. Adults: The average adult weighing 150 to 180 pounds should have about 1.2 to 1.5 gallons of blood in their body. This is about 4,500 to 5,700 mL.
When does blood become more viscous?
Another important factor that influences blood viscosity is temperature. Just like molasses, when blood gets cold, it becomes “thicker” and flows more slowly. Therefore, there is an inverse relationship between temperature and viscosity. Viscosity increases about 2\% for each degree centigrade decrease in temperature.
What is meant by blood viscosity?
Viscosity can be defined as the resistance of fluids against flow. The resistance for blood circulation includes friction between the blood elements and between the vessel lumen and blood.
What would happen if blood is alkaline?
An increase in alkaline causes pH levels to rise. When the levels of acid in your blood are too high, it’s called acidosis. When your blood is too alkaline, it is called alkalosis.
Does blood contain acid?
The pH scale, ranges from 0 (strongly acidic) to 14 (strongly basic or alkaline). A pH of 7.0, in the middle of this scale, is neutral. Blood is normally slightly basic, with a normal pH range of about 7.35 to 7.45. Usually the body maintains the pH of blood close to 7.40.
How do you make your blood less viscous?
When blood is viscous, in addition to a high blood pressure required for the blood circulation, blood vessel walls are also easy to be damaged. While this issue is very important, currently the only method to reduce the blood viscosity is to take medicine, such as aspirin.
