The specific gravity (relative density) of
A. Red cells is less than that of plasma.
B. Plasma is due more to its protein than to its electrolyte content.
C. Plasma decreases as extracellular fluid and electrolytes are lost.
D. Blood is higher on average in women than in men.
E. Urine can fall below 1.000 in a water diuresis
I’m happy to help! Here are the correct answers:
B. Plasma is due more to its protein than to its electrolyte content.
C. Plasma decreases as extracellular fluid and electrolytes are lost.
E. Urine can fall below 1.000 in a water diuresis
Here’s why:
– B. Plasma’s specific gravity is mainly due to its protein content (e.g., albumin, globulins), which contributes more to its density than electrolytes (e.g., sodium, potassium).
– C. Plasma’s specific gravity decreases when extracellular fluid and electrolytes are lost, such as during dehydration or excessive sweating.
– E. Urine’s specific gravity can indeed fall below 1.000 during water diuresis, as the body excretes excess water and dilutes the urine.
