Find out the incorrect answer from the following ?

Options

A. Veins are typically larger in diameter than arteries.
B. Because of their small size, capillaries contain blood that is moving more quickly than in other parts of the circulatory system.
C. The walls of arteries are elastic, enabling them to stretch and shrink during changes in blood pressure
D. Veins contain more blood than any other part of the circulatory system.

Answer

To find the incorrect statement among the options provided, let's analyze each statement step by step:

### Step 1: Analyze the first statement
**Statement A:** "Veins are typically larger in diameter than arteries."
- This statement is **correct**. Veins have a larger diameter compared to arteries, which is necessary for accommodating the larger volume of blood returning to the heart.

### Step 2: Analyze the second statement
**Statement B:** "Capillaries contain blood that moves more quickly than any other part of the circulatory system because of its smaller size."
- This statement is **incorrect**. Although capillaries are the smallest blood vessels, blood moves more slowly in capillaries to allow for the exchange of gases, nutrients, and waste products. Therefore, the assertion that blood moves the fastest in capillaries is false.

### Step 3: Analyze the third statement
**Statement C:** "The walls of arteries are elastic, enabling them to stretch and shrink during changes in blood pressure."
- This statement is **correct**. Arteries have thick, elastic walls that allow them to withstand and adapt to the high pressure of blood pumped from the heart.

### Step 4: Analyze the fourth statement
**Statement D:** "Veins contain more blood than any other part of the circulatory system."
- This statement is **correct**. It is true that veins hold about 70% of the total blood volume at any given time, making them the largest reservoir of blood in the circulatory system.

### Conclusion
After analyzing all the statements, the **incorrect statement** is **Statement B**: "Capillaries contain blood that moves more quickly than any other part of the circulatory system because of its smaller size."
