Statement 1: Arteries carry blood towards the heart from various body parts. Statement 2: Arteries have thick and elastic walls. A) Statement 1 is true but Statement 2 is false B) Statement 1 is false but Statement 2 is true C) Both Statement 1 and Statement 2 are true D) Both Statement 1 and Statement 2 are false
Question 21 Choose the correct statement that describes arteries. (a) They have thick elastic walls, blood flows under high pressure; collect blood from different organs and bring it back to the heart. (b) They have thin walls with valves inside, blood flows under low pressure and carries blood away from the heart to various organs of the body. (c) They have thick elastic walls, blood flows under low pressure; carry blood from the heart to various organs of the body. (d) They have thick elastic walls without valves inside, blood flows under high pressure and carries blood away from the heart to different parts of the body.
Arteries have thick walls as they carry oxygenated blood with high pressure from the heart to all body parts. Veins on the other hand have thin walls and carry deoxygenated blood from the body towards the heart. From this we conclude- The more the blood pressure, the _______ the walls of blood vessels.
