Find the incorrect statement from the following

Options

A. veins are larger in diameter than arteries
B. wall of arteries are elastic, enabling them to stretch and shrink during changes in blood pressure
C. veins contain maximum amount of blood
D. because of their small size, capillaries contain blood that moves more quickly than in other part of circulation

Explanation

To find the incorrect statement among the provided options, we will analyze each statement one by one.

1. **Statement 1**: "Veins are larger in diameter than arteries."
- **Analysis**: This statement is correct. Veins typically have a larger diameter compared to arteries. They carry more volume of blood and have thinner walls than arteries.

2. **Statement 2**: "Walls of arteries are elastic enabling them to stretch and shrink during changes in blood pressure."
- **Analysis**: This statement is also correct. The walls of arteries contain elastic fibers and connective tissues that allow them to stretch and accommodate changes in blood pressure.

3. **Statement 3**: "Veins contain maximum amount of blood."
- **Analysis**: This statement is correct as well. Veins do contain a larger volume of blood compared to arteries due to their larger diameter and capacity to hold more blood.

4. **Statement 4**: "Because of their small size, capillaries contain blood that moves more quickly than in any other parts of the circulation."
- **Analysis**: This statement is incorrect. In fact, capillaries have the slowest blood flow compared to other parts of the circulatory system. As blood moves from arteries to arterioles and then into capillaries, its speed decreases significantly, allowing for nutrient and gas exchange.

**Conclusion**: The incorrect statement is the fourth one: "Because of their small size, capillaries contain blood that moves more quickly than in any other parts of the circulation."
