Which of the following statements about hormones is incorrect ?

Options

A. Glands that produce them are ductiess glands
B. They are produced only by organs called endocrine organs
C. Some are water soluble and some are not
D. They often maintain steady-state conditions

Answer

To determine which statement about hormones is incorrect, we will analyze each option provided:

### Step-by-Step Solution:

1. **Evaluate Option 1**:
- The statement claims that glands that produce hormones are ductless glands.
- **Analysis**: This is true. Endocrine glands, which produce hormones, do not have ducts and release hormones directly into the bloodstream.
- **Conclusion**: Option 1 is correct.

2. **Evaluate Option 2**:
- The statement claims that hormones are produced only by organs called endocrine organs.
- **Analysis**: This is incorrect. While endocrine glands are the primary producers of hormones, other organs can also produce hormones. For example, the kidneys produce erythropoietin, which is a hormone involved in red blood cell production, even though the kidneys are not classified as endocrine organs.
- **Conclusion**: Option 2 is incorrect.

3. **Evaluate Option 3**:
- The statement claims that some hormones are water soluble and some are not.
- **Analysis**: This is true. Hormones can be classified based on their solubility; some are hydrophilic (water-soluble), while others are hydrophobic (water-insoluble). Examples include protein-based hormones (hydrophilic) and steroid hormones (hydrophobic).
- **Conclusion**: Option 3 is correct.

4. **Evaluate Option 4**:
- The statement claims that hormones often maintain a steady state condition.
- **Analysis**: This is true. Hormones play a crucial role in maintaining homeostasis, which is the steady state condition in the body.
- **Conclusion**: Option 4 is correct.

### Final Conclusion:
After evaluating all options, the incorrect statement about hormones is **Option 2**: "They are produced only by organs called endocrine organs."
