Which of the following tissues is most affected due to the deficiency of oxygen?

Options

A. Cardiac muscles
B. Visceral muscles
C. Hyaline cartilage
D. Long bones

Explanation

To determine which tissue is most affected by a deficiency of oxygen, we need to analyze the options provided and understand the role of each tissue in oxygen utilization.

### Step-by-Step Solution:

1. **Identify the Tissues**: The question presents several tissues, including cartilage, bone, cardiac muscle, and visceral muscle. We need to evaluate how each of these tissues responds to oxygen deficiency.

2. **Understand the Function of Each Tissue**:
- **Cartilage and Bone**: These are connective tissues that primarily provide structural support to the body. They have a lower metabolic rate and do not require a constant supply of oxygen for their function. While they contain living cells, they do not actively participate in respiration.
- **Visceral Muscle**: This muscle type is found in the walls of internal organs and is involved in involuntary movements. While it does require oxygen, it is not as critically dependent on a continuous supply as cardiac muscle.
- **Cardiac Muscle**: This muscle is found exclusively in the heart and is responsible for pumping blood throughout the body. Cardiac muscle cells have a high metabolic demand and require a constant supply of oxygen to function effectively.

3. **Analyze the Impact of Oxygen Deficiency**:
- If oxygen levels drop, the tissues that are most reliant on oxygen for their function will be affected first.
- **Cardiac Muscle**: A deficiency of oxygen in cardiac muscle can lead to serious consequences, including the heart's inability to pump blood, which would disrupt oxygen supply to all other tissues in the body.
- **Cartilage and Bone**: These tissues can tolerate lower oxygen levels without immediate adverse effects due to their lower metabolic activity.

4. **Conclusion**: Based on the analysis, the tissue most affected by oxygen deficiency is the **cardiac muscle**. If the cardiac muscle does not receive enough oxygen, it cannot function properly, leading to a failure in blood circulation and oxygen delivery to other tissues.

### Final Answer:
The tissue most affected due to the deficiency of oxygen is **Cardiac Muscle**.
