| Why does my body sweat when I play hard? | ||||||||||||||||||||||||
|
Your body sweats to cool you down. Your body produces more heat when you exercise and that makes your body temperature go up. Then your brain sends messages to your body to get rid of the extra heat. So the extra body heat moves from inside your body to the surface of your skin where it evaporates into the air in the form of sweat. That cools you down. Why is it important to drink plenty of
water when you exercise?

| What does my pulse measure? | ||||||||||||||||||||||||
|
Your pulse measures how fast your heart is
beating. Each time your heart beats it sends blood out of your heart
into your arteries. Your pulse is like a wave or a ripple through your
arteries that you can feel with every heart beat. We call the number of
pulse beats we feel in one minute a pulse rate. |

| What is my pulse rate? | ||||||||||||||||||||||||
 You can count your own pulse rate. Look at
the picture and see if you can feel your own
pulse. Nurses often check a pulse on the wrist. Now count the
number of beats you can feel in one minute This works best if you have a
watch or clock with a second hand on it. |

| What is respiration rate? | ||||||||||||||||||||||||
|
The number of times you
breath in one minute is called your respiration rate. See the chart for
normal respiration rates for different age groups. |

| How are respirations important to the body? | ||||||||||||||||||||||||
|
Respiration is another word
for breathing. Breathing or respiration is the method by which the body
brings fresh oxygen into the arterial blood and removes carbon dioxide
from venous blood.

| What does blood pressure mean? | ||||||||||||||||||||||||
Blood
pressure tells you the highest and lowest pressure in your arteries with
every heart beat. So blood pressure gives information about your heart
when it is working and when it is resting. There are two numbers that
give information about your heart and blood vessels.
Systolic tells you the greatest amount of pressure the heart puts on the artery walls when it pumps blood out of the heart and into the blood vessels. Diastolic tells you the least
pressure during short time the heart is relaxed after pumping blood into
the artery. |
||||||||||||||||||||||||
| Does blood pressure stay the same all the time? | ||||||||||||||||||||||||
|
No. In healthy people there is a range of
normal blood pressure that occurs. For example, before you get up in the
morning your blood pressure is a little bit lower than it will be later
on when you are active. |
