Can you explain the answer of this question below:In older people heart pumps blood more forcefully than in younger persons because of:A:Decrease in O2content in blood.B:Fall in nutritional control of bloodC:Decrease in elasticity&rsquo;s of arteriesD:Increase in elasticity of arteriesThe answer is c.

Answer

Decrease in elasticity of arteries

When the heart pumps blood, it creates pressure that pushes the blood through the arteries and circulates it to various parts of the body. The arteries are responsible for carrying oxygenated blood from the heart to the rest of the body. However, as a person gets older, the arteries tend to lose their elasticity, becoming stiffer and less flexible.

Effects of decreased elasticity:

1. Increased resistance: As the arteries lose their elasticity, they become stiffer and less able to expand and contract. This leads to increased resistance against the flow of blood, requiring the heart to pump more forcefully to maintain adequate blood flow to the body's organs and tissues.

2. Higher blood pressure: The loss of elasticity in the arteries also contributes to an increase in blood pressure. When the arteries are less flexible, they cannot expand and contract efficiently, causing the blood pressure to rise. This puts additional strain on the heart, which has to work harder to overcome the increased resistance and pump blood effectively.

3. Reduced blood flow: The decreased elasticity of arteries can also lead to reduced blood flow to various parts of the body. The stiff arteries cannot expand as they should, resulting in a decrease in the amount of blood reaching organs and tissues. This can lead to reduced oxygen and nutrient supply, affecting their proper functioning.

Conclusion:

In older individuals, the decrease in elasticity of arteries puts additional strain on the heart, requiring it to pump blood more forcefully to compensate for the increased resistance. This can lead to higher blood pressure, reduced blood flow, and potential complications in various organs and tissues. Therefore, the correct answer to the given question is option 'B' - decrease in elasticity of arteries.
