Question

If the amount of urine produced were different in the two conditions, how would that affect your calculation? Explain.

Short answer

Yes, if the amounts are not the same regarding urine production, it will change the value of the ratio. If the value of the urine osmolality is lower than the blood osmolarity, it means in the blood, the number of solutes is higher than urine and vice versa.

Step-by-step solution

Osmotic homeostasis

Temperature and weather conditions influence osmotic homeostasis. Osmoregulation is the condition where the water levels and the amount of salt in the blood will get maintained.

The process of osmoregulation is vital to maintain the equilibrium of the concentrations (both inside and outside of the cell).

Urine composition

Urine has many components, including i) urea, ii) water, iii) creatinine, iv) inorganic salts, v) ammonia, vi) uric acid, and vii) different ions. Urochrome is a pigment for which the color of the blood is yellowish.

Urine is essential because it removes excess water and unnecessary waste materials. The urinary tract drains urine from the kidney and is vital for the regulation of homeostasis.

Urine production for different conditions

More urine production can decrease the osmolality of urine because the blood has an excess amount of water or fluid content. When the body gets dehydrated or has a lower amount of fluids, the urine osmolality will increase.

Increased urine osmolality will trigger the body to produce antidiuretic hormone. If the urine osmolality is higher than the standard value, it may indicate some conditions, including Addison disease and others.

Hence, if conditions and urine production are different, it also affects the calculations.
