### Step 1: Define the Problem
Identify which option is not a function of the kidneys.

### Step 2: Break Down the Problem
Examine each option to determine if it is a known function of the kidneys.

### Step 3: Apply Relevant Concepts
- **(A) Removal of waste products from the blood:** The kidneys filter waste products from the blood, which is a primary function.
- **(B) Maintenance of blood pH:** The kidneys help regulate blood pH by excreting hydrogen ions and reabsorbing bicarbonate.
- **(C) Regulation of water content of the blood:** The kidneys regulate the body's water balance by adjusting urine concentration.
- **(D) Maintenance of homeostasis:** The kidneys contribute to homeostasis by regulating electrolytes, blood pressure, and red blood cell production.
- **(E) Excretion of carbon dioxide:** Carbon dioxide is primarily excreted by the lungs, not the kidneys.

### Step 4: Analysis, Verify and Summarize
Verify each function against known kidney functions. The kidneys do not excrete carbon dioxide; this is the role of the respiratory system.

### Final Answer
(E) excretion of carbon dioxide.
