Consider the following statements : Statement I: The blood arteries have thick and rigid walls. Statement II: Arteries carry oxygen-rich blood from heart to various body organs under high pressure. In the light of the above statements, choose the correct answer from the options given below :
Artery Statements: Detailed Analysis
We will analyze the two statements regarding blood arteries to determine their correctness and relationship.
Statement I: Wall Properties
Statement I claims: "The blood arteries have thick and rigid walls." This statement is considered incorrect. While arteries do possess thick and strong walls to withstand high blood pressure, they are also highly elastic. This elasticity is crucial for them to stretch and recoil with each heartbeat, which helps maintain blood flow and pressure. The term 'rigid' does not fully encompass this vital elastic characteristic.
Statement II: Blood Transport Function
Statement II claims: "Arteries carry oxygen-rich blood from heart to various body organs under high pressure." This statement is correct. Arteries are defined as blood vessels that carry blood away from the heart. In the systemic circulation (the pathway to the body), arteries generally transport oxygenated blood. This blood is expelled from the heart at high pressure during ventricular contraction.
Final Conclusion
Based on the analysis:
- Statement I is incorrect because it overlooks the crucial elasticity of arterial walls, focusing only on thickness and rigidity.
- Statement II is correct, accurately describing the general function and pressure dynamics of arteries in the systemic circulation.
Therefore, the correct option corresponds to Statement I being incorrect and Statement II being correct.
