Question

Imagine that you have been drinking a large amount of relatively pure water over the course of the day, enough to drop the osmolarity of your body fluids down from a normal level (300 mOsm) to an abnormally low level (295 mOsm). Soon after this, which of the following statements do you predict will be true? Select ALL that will be true.
A) Following this you will produce urine with a U/P ratio < 1.

B) Following this you will produce hyperosmotic urine.

C) Following this you will temporarily be less thirsty than usual.

D) Following this you will temporarily generate metabolic water at a slower rate than usual.

E) Following this you will temporarily lose water via evaporation across your lung epithelia at a faster rate than usual.

Answer 1

Answer:

the correct answer is C

Explanation:

Faced with this situation, there is hyposmolarity that excessively increases the solvent and the solute is found in a lower concentration in the solution, in this case when speaking of the organism we would be speaking of blood.

The blood volume will increase, the blood pressure too, therefore the glomerular filtration will be higher and the urine will be increased but with less concentration of solutes, therefore hyposmolar.

In the case of the respiratory system, part will excrete as water vapor and another will excrete the epithelium as perspiration.

For all this that occurs in the body, the person will then be less thirsty than usual until equilibrium is reached, since the pressure will be increased, the osmolarity will be decreased and the renal excression will also be increased until the moment they reach the volemia and the balanced osmolarity. system
