You are going to determine on average how many breaths you take in one day, one week, and one year.  You will also be determining the amount of air that moves through your lungs in one day, one year, and ten years.

Beginning Information
TV (Tidal Volume) is the amount of air that moves in and out of the lungs in a normal breath.  The average TV for an individual is 500 ml for every normal breath taken.

Activity
Watch the second hand on the clock for one minute.  During this minute count how many breaths you take (breathing in and out counts as one breath).  Record this data on the paper provided, then record the following data:
How many breaths do you take in one day?
one week?
one year?
 

Using the information that you just found and the beginning information that was provided, determine the amount of air that moves through your lungs in:
one day?
one year?
ten years?
How many breathes will you have taken when you are 78 years old?

Graph your results for the data you collected.  Put into words what your graph tells you about your tidal volume.
Now collect the data of three of your group members and make a graph showing all three members as well as your data on one graph (use a different color for each member).

Using everything you know so far about the respiratory system determine different factors that would affect the average number of breaths you take and the average volume of air that moves through your lungs.  Provide one situation in which an individual's breathing rate or tidal volume would be greater than the normal rate record this information.  Predict how much greater that individual's rate would be than the normal breathing rate that you have been working with.

Today you are going to figure out how many times that your heart beats in your lifetime.  You must also find out how many times your heart beats in one minute, one hour, one day, and one year.

To find your heart rate you must measure your pulse for 15 seconds.  Take that number times four to find your pulse rate for one minute.

Now using the information that you just found how many times does your heart beat in :
one day?
one year?
your lifetime?

The next thing that you will do is compare how many times your heart will beat when you are seventy from when you were ten.  You will collect data from the rest of the group and make two separate tables for age seventy and age ten.

The next thing that you will do is make one graph with two lines on it, each line representing a different age.  You will use correct labels and symbols and also a creative title.

If blood makes a complete cycle through your body in 23 seconds, how many cycles does your blood make in 24 hours?

Blood travels 100 m per minute through your body.  Calculate how far one blood cell would have traveled in one hour.
one day?
one week?

In one day the heart pumps nearly 2,000 gallons of blood each day.
How many gallons does your heart pump in two days?
one week?
one 30 day month?
one year?
your lifetime?

Research facts about the heart using this link and write three math problems that you can solve.
