Hyproxia corresponds to

Options

A. any change in the relative rates of development of different cell lines in body
B. hardening and loss of elasticity of arteries
C. deficiency of oxygen in body tissues
D. sudden interruption of blood flow to a portion of brain due to blockage of cerebral blood vessel

Answer

**Step-by-Step Text Solution:**

1. **Understanding Hypoxia**: Hypoxia is defined as a condition where there is a deficiency of oxygen in the body tissues. This can occur in specific parts of the body or can affect the entire body.

2. **Evaluating the Options**:
- **Option A**: This option describes heterochrony, which refers to any change in the relative rate of development of different cell lines. This is not related to hypoxia, so it is incorrect.
- **Option B**: This option mentions hardening and loss of elasticity of arteries, which is a characteristic of arteriosclerosis. This does not describe hypoxia, so it is also incorrect.
- **Option C**: This option states that hypoxia corresponds to a deficiency of oxygen in the blood tissues. This is the correct definition of hypoxia.
- **Option D**: This option describes a sudden interruption of blood flow to a portion of the brain due to blockage of cerebral blood vessels, which is known as cerebral hemorrhage. This is not related to hypoxia, making it incorrect.

3. **Conclusion**: After evaluating all the options, the correct answer is **Option C**, which states that hypoxia corresponds to a deficiency of oxygen in body tissues.
