When the oxygne supply to the tissue is inahequaate the condition is

Options

A. asphyxia
B. apnea
C. dyspenea
D. hypoxia

Answer

To solve the question "When the oxygen supply to the tissue is inadequate, the condition is:", we need to analyze the given options: asphyxia, apnea, dyspnea, and hypoxia.

### Step-by-Step Solution:

1. **Understanding Asphyxia**:
- Asphyxia refers to a condition where there is a deficiency of oxygen supply to the entire body. This usually occurs due to abnormal breathing patterns.
- **Conclusion**: Asphyxia is related to overall oxygen deficiency but not specifically to tissue oxygen supply.

2. **Understanding Apnea**:
- Apnea is defined as the complete cessation of breathing. In this condition, there is no inhalation or exhalation, leading to a lack of airflow.
- **Conclusion**: Apnea indicates a lack of breathing rather than a specific deficiency of oxygen in the tissues.

3. **Understanding Dyspnea**:
- Dyspnea refers to shortness of breath. It can occur due to various reasons such as airway blockage or lung inflammation.
- **Conclusion**: While dyspnea indicates difficulty in breathing, it does not specifically denote inadequate oxygen supply to tissues.

4. **Understanding Hypoxia**:
- Hypoxia is characterized by a deficiency of oxygen in the tissues. This condition can arise even when oxygen is present in the environment but is not effectively delivered to the tissues (e.g., due to carbon monoxide poisoning).
- **Conclusion**: Hypoxia directly refers to inadequate oxygen supply to tissues.

5. **Final Answer**:
- Based on the definitions and explanations, the correct answer to the question is **Hypoxia**.
