What is the significance of a person in having a low resting heart rate?

For some people a low resting heart rate is fine.

Explanation: Usually this means they are fit and conditioned, allowing for their heart rate to be lower than normal. In other people, bradycardia is a sign of a problem with the heart's electrical system.

I dont know if this helped, im sorry!

blood alcohol concentration is affected by factors such as body size and gender.

( i saw this one before)

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
