Excess consumption of ethanol causes damage to:

Options

A. Liver
B. Kidney
C. Lungs
D. Heart

Answer

### Step-by-Step Solution:

1. **Understanding Ethanol Consumption**: Ethanol is the type of alcohol found in alcoholic beverages. Excessive consumption of ethanol is commonly referred to as alcohol abuse.

2. **Effects on the Body**: When ethanol is consumed, it is primarily metabolized in the liver. The liver processes a significant amount of alcohol, and this can lead to various health issues.

3. **Liver Damage**: Continuous and excessive intake of ethanol puts a strain on the liver. The liver cells are responsible for metabolizing alcohol, and over time, this can lead to damage.

4. **Regenerative Ability**: The liver has a remarkable ability to regenerate. However, with chronic alcohol abuse, this regenerative capacity is inhibited. This means that the liver cells cannot repair themselves effectively, leading to further damage.

5. **Diseases Caused by Liver Damage**: Chronic ethanol consumption can lead to serious liver conditions such as hepatitis (inflammation of the liver), liver cirrhosis (severe scarring of the liver), and ultimately, liver cancer.

6. **Conclusion**: Therefore, the primary organ affected by the excess consumption of ethanol is the liver. While other organs may be indirectly affected, the liver is the most directly damaged.

### Final Answer:
Excess consumption of ethanol causes damage to the **liver**.
