Find out the incorrectyly matching pair w.r.t. the accessory excretory organs and the excretory wastes eliminated by them

Options

A. Liver-Bilirubin, biliverdin and cholesterol
B. Lungs-`CO_(2)and H_(2)O`
C. Salivary gland- Heavy metals, drugs, small amounts of nitrogenous wastes
D. Sudorfic gland-Sebum containing waxes, sterols and fatty acids

Answer

To find the incorrectly matching pair with respect to the accessory excretory organs and the excretory wastes eliminated by them, we can analyze each option provided:

1. **Liver**: The liver is known to excrete bile pigments such as bilirubin, as well as cholesterol. This is a correct match.

2. **Lungs**: The lungs are responsible for the excretion of carbon dioxide (CO2) and water (H2O) through respiration. This is also a correct match.

3. **Salivary Glands**: The salivary glands secrete saliva, which can contain small amounts of nitrogenous wastes, drugs, and heavy metals. This is another correct match.

4. **Sudoriferous Glands (Sweat Glands)**: These glands excrete sweat, which primarily consists of water, salts, and some metabolic waste. However, the option incorrectly states that they excrete sebum, which contains waxes, steroids, and fatty acids. Sebum is actually produced by the sebaceous glands, not the sudoriferous glands.

Thus, the incorrectly matching pair is the fourth option: **Sudoriferous Glands and Sebum**.

### Step-by-Step Solution:
1. **Identify the accessory excretory organs**: Liver, Lungs, Salivary Glands, Sudoriferous Glands.
2. **Determine the excretory wastes for each organ**:
- **Liver**: Excretes bile pigments (bilirubin) and cholesterol.
- **Lungs**: Excretes carbon dioxide (CO2) and water (H2O).
- **Salivary Glands**: Excretes saliva containing nitrogenous wastes, drugs, and heavy metals.
- **Sudoriferous Glands**: Excretes sweat (water, salts, metabolic wastes).
3. **Check for incorrect matches**:
- Liver: Correct
- Lungs: Correct
- Salivary Glands: Correct
- Sudoriferous Glands: Incorrectly matched with sebum.
4. **Conclusion**: The incorrect match is between Sudoriferous Glands and Sebum.
