If human arteries were rigid instead of elastic, what would you notice about your pulse, according to the source?
AYour pulse would only be felt in your legs
BYour pulse would feel exactly the same as it does now
CYour pulse would become faster than normal
DYou would not feel any pulse whatsoever
Answer & Solution
Correct answer: D. You would not feel any pulse whatsoever
1. Feeling a pulse comes from the elastic stretching and relaxing of artery walls as blood is pumped through them.
2. It states plainly that if the arteries were rigid, you would not feel a pulse.
3. This directly rules out the option claiming the pulse would feel unchanged if arteries lost their elasticity.
4. Nothing here suggests pulse location or pulse rate would shift instead, only that the pulse sensation itself depends on arterial elasticity.
