IN an aging person ,there is a

Options

A. Increase in mucopolysaccharide cement of connective tissue
B. Gradual alteration in components of connective tissue
C. Increasing collagen rigidity of connective tissue
D. Both B and C

Answer

To answer the question regarding changes in an aging person, let's break down the information step by step.

### Step-by-Step Solution:

1. **Understanding Aging Changes**: As a person ages, various physiological changes occur in the body, particularly in connective tissues. This includes alterations in the composition and structure of these tissues.

2. **Mucopolysaccharide Cement**: Aging is associated with an increase in mucopolysaccharide cement in connective tissues. Mucopolysaccharides are important for maintaining the structural integrity and hydration of connective tissues.

3. **Gradual Alteration in Connective Tissue**: With age, there is a gradual alteration in the components of connective tissue. This means that the proteins and other molecules that make up these tissues may change in quantity and quality, affecting their function.

4. **Collagen Rigidity**: One of the significant changes in aging connective tissue is the increasing rigidity of collagen. Collagen is a major structural protein in connective tissues, and as it becomes stiffer, it can lead to reduced flexibility and increased susceptibility to injury.

5. **Conclusion**: Based on the analysis, the correct answer to the question is option D, which states that both B (gradual alteration in components of connective tissue) and C (increasing collagen rigidity of connective tissue) are correct.

### Final Answer:
In an aging person, there is both a gradual alteration in components of connective tissue and an increase in collagen rigidity of connective tissue (Option D: Both B and C).
