---------------- Through blood vessels. These include: -Arteries: Thick and elastic, transport blood away from the heart. -Veins: Thin, slightly elastic, transport blood back to the heart, contain valves to prevent back flow of blood. -Capillaries- extremely thin, where exchange of materials occurs.
How do you know how fast your heart is beating?
You can tell how fast your heart is beating (your heart rate) by feeling your pulse. Your heart-rate is the amount of times your heart beats in one minute.
You will need a watch with a second hand.
Place your index and middle finger of your hand on the inner wrist of the other arm, just below the base of the thumb.
You should feel a tapping or pulsing against your fingers.
Count the number of taps you feel in 10 seconds.
Multiply that number by 6 to find out your heart-rate for one minute:
Pulse in 10 seconds x 6 = ____ beats per minute (your heart-rate)
When feeling your pulse, you can also tell if your heart rhythm is regular or not.
