Why does dehydration result in a raised red blood cell concentration?
Dehydration reduces blood volume without changing the number of blood cells, so their concentration increases.
A person suffering from hyponatremia has a sodium ion concentration in the blood of 0.120 M and a total blood volume of 4.8 L?

What happened to the urine volume as the concentration gradient increased?
The urine volume decreased as the concentration gradient increased.
Why use plasma concentration rather than blood concentration in monitoring drug concentration in the body?
Most compounds are given as their concentration in blood plasma as well as with the conditions of collection. It is a form of standardization used in order to compare results across laboratories and over time. As blood volume and percent hematocrit (a measure of red blood cells) are fairly constant relative to body mass using the concentration in plasma ensures consistency in measurement. Another factor is that red blood cells are not equilibrated with the concentration of all compounds outside the cell equally. Transportation of compounds across the cell membrane is regulated.
Is the amount of a substance in a given volume the concentration of the substance?
Ye.. the concentration of a substance is measured as the amount of substance per unit volume. Accordingly, the amount of a substance in per unit volume is the concentration of the substance.
Blood Alcohol Concentration is the amount of alcohol in an individual's body measured by the weight of the alcohol in a volume of blood.?

Why does dehydration result in a raised red blood cell concentration?
Dehydration reduces blood volume without changing the number of blood cells, so their concentration increases.
What is hemo-concentration?
Hemoconcentration occurs when there is an increase in the concentration of blood cells as the result of the loss of plasma from the bloodstream. A decrease in volume of plasma and an increase in red blood circulating.
What is platelet concentrate?
Platelets are important in the human blood system. Platelet concentration is the amount of platelets in a measured volume of blood.
What effect does salt intake have upon urine salt concentration and volume?
The renal system (kidneys) is the main regulator of both blood volume and blood salt concentration, but the two factors are regulated somewhat independently of each other as both the volume of urine produced and it's salt concentration vary with their own hormone system.

What mass of sodium chloride would need to be added to the blood to bring the sodium ion concentration up to 0.140m assuming no change in blood volume?
5.8g of sodium chloride would need to be added to the blood to bring the sodium ion concentration up to 0.140m with no change in blood volume. This is also known as the Ionic strength.
What Blood alcohol concentration is a measurement of the level of alcohol in the bloodstream and is shown in milligrams of alcohol per how many milliliters of blood?
% volume
What is a concentration of a solution?
The concentration of a solution is basically how strong the solution is.
Is concentration typically given with the volume of solvent or the volume of solution?
The concentration of a solution is typically given in terms of the volume of solution, in liters.
What happened to the urine volume as the concentration gradient increased?
The urine volume decreased as the concentration gradient increased.
