,### 1. Which of the following statements is true regarding nephrons?
- It is divided into an outer medulla and an inner cortex
- It has 1 source of blood supply
- The glomerulus filters the blood while the tubule reabsorbs needed nutrients
Correct Answer: The glomerulus filters the blood while the tubule reabsorbs needed
nutrients
Verified Explanation:
The glomerulus acts as the primary site for filtration of the blood, while the nephron
tubules are responsible for selective reabsorption of essential substances and water.

### 2. Excess accumulation of fluid within the interstitial compartment is
characteristic of which of the following fluid imbalances?
- Dehydration
- Water intoxication
- Edema
Correct Answer: Edema
Verified Explanation:
Edema is defined as the pathological accumulation of fluid in the interstitial space,
resulting from imbalances in hydrostatic, oncotic, or permeability dynamics.
### 3. Each of the following statements are true regarding control over the GFR
except:
, - The kidney can maintain a constant GFR despite variations in the arterial blood
pressure of the rest of the body.
- The sympathetic nervous system can supersede the renal autoregulatory system.
- The RAA responds when blood pressure rises above normal limits.
- The RAA responds when blood pressure drops below normal limits.
Correct Answer: The RAA responds when blood pressure rises above normal limits.
Verified Explanation:
The renin-angiotensin-aldosterone (RAA) system is activated in response to decreased
blood pressure, not increased. Its primary function is to restore perfusion pressure by
promoting vasoconstriction and sodium/water reabsorption.

### 4. Which of the following statements is FALSE regarding ADH?
- Elevated levels of ADH will lead to a small volume of concentrated urine.
- Decreased levels of ADH will lead to dilute urine.
- Alcohol increases ADH levels.
- Elevated levels of ADH will lead to dilute urine.
Correct Answer: Alcohol increases ADH levels.
Verified Explanation:
Alcohol actually inhibits the release of antidiuretic hormone (ADH), resulting in
increased urine output and potential dehydration. Therefore, stating alcohol increases
ADH is incorrect.

### 5. ADH levels will rise under which of the following circumstances?
