If kidneys fails to reabsorb water, the effect on tissue would

Options

A. remain unaffected
B. shrink and shrivel
C. absorb water from blood plasma
D. take more `O_(2)` from blood

Explanation

**Step-by-Step Solution:**

1. **Understanding Kidney Function**: The kidneys play a crucial role in maintaining water balance in the body by reabsorbing water from the filtrate back into the bloodstream. This process helps regulate blood volume and plasma concentration.

2. **Effect of Kidney Failure on Water Reabsorption**: If the kidneys fail to reabsorb water, the body will not retain enough water, leading to a decrease in blood volume. This results in an increase in plasma concentration (the concentration of solutes in the blood).

3. **Consequences of Decreased Blood Volume**: With less water in the blood, the kidneys will produce more dilute urine, leading to frequent urination. As the body loses more water, the tissues will start to experience a deficiency of water.

4. **Impact on Tissues**: The tissues in the body rely on adequate hydration to function properly. When the tissues lose water, they undergo dehydration, which causes them to shrink and shrivel due to the lack of sufficient fluid.

5. **Conclusion**: Therefore, if the kidneys fail to reabsorb water, the primary effect on the tissues would be that they will shrink and shrivel due to dehydration.

**Final Answer**: The effect on tissue would be that they shrink and shrivel.
