1. The document provides information about cardiovascular and respiratory health, including how the heart pumps blood through 60,000 miles of blood vessels, how the lungs exchange oxygen and carbon dioxide through alveoli, and how aerobic exercise strengthens the heart and lungs. 2. It encourages students to take care of their heart and lungs by choosing not to smoke, exercising aerobically by keeping their heart rate in their target zone for duration, and remembering to warm up, cool down, and stay hydrated. 3. The key aspects of cardiovascular and respiratory health that students should understand are how the heart, blood vessels, lungs, and alveoli work together to supply oxygen to the body and remove carbon dioxide,
![In Summary…..
• Cardiovascular Health is very
Important, even Against Genetics, you
can work to make your Heart Healthy
• Work Smart not Hard, Remember to
spot check for your Target Heart Rate
• Don’t forget to Drink LOTS of
water, and to warm up and cool down
every time you exercise! :-]](https://image.slidesharecdn.com/peunit3bcardiovascularsystemhealthclassconnectversion-120220213329-phpapp02/85/Pe-Cardiovascular-System-health-class-connect-version-23-320.jpg)

- 1. Announcements: 1. HSPE Registration Open now at nnvacommunity.org 10th – 12th graders 3/5 - 3/9 2. If you are not passing then you are absent 3. Look in grade book and turn in zeros 4. You can retake low scoring quizzes
- 2. Unit Objectives • Understand the importance of a strong heart and respiratory system to overall health. • Learn the benefits of aerobic exercise and how to measure different heart rates.
- 3. Unit 3: Cardiovascular and Respiratory Health Are you feeling better, physically, than you did at this point in the first semester? If you have been exercising as your logs indicate, then the answer should be yes!
- 4. You have many different systems in your body, a few listed below: Muscular Skeletal Nervous Endocrine Cardiovascular
- 5. the respiratory system controls the flow of oxygen in your body. The circulatory system controls the flow of Together, th oxygenated ese two blood to all parts systems of your body make up your cardiovascu lar system.
- 6. If all the blood vessels in your body were laid out in a straight line, How far would they stretch? A- To New York and Back from Las Vegas 2980 miles B- 2 ½ times around the earth 62, 147 miles C –From Earth to the moon– 238,857 miles
- 7. Cardiovascular and Respiratory Health…… Your heart keeps blood flowing through this 60,000-mile network called your body, 24 hours a day, every day of your life.
- 8. These blood vessels receive oxygen from your lungs. What size best describes the lungs located in your chest? A - A pair of football-sized organs also located in your chest. B - A pair of soccer shoes. C - Pair of water melons
- 9. Cardiovascular System Four valves in your heart open and close in perfect rhythm, pumping oxygen-rich blood through your Blood vessels; arteries (carry air). These major blood vessels branch out into much smaller tubes, called capillaries , that carry the fresh blood to every cell in your body. The capillaries then return the oxygen- depleted blood to large veins that flow back into the heart, and the whole process is repeated.
- 10. How much blood does your body contain which your heart constantly recirculates throughout your tissues and cells? A- 12 quarts B - 5 ½ quarts C - 1 quart
- 11. A man weighing 154 pounds would have about 5.5 quarts (5.2 liters) of blood. A woman weighing 110 pounds would have about 3.5 quarts.
- 12. This hardworking muscle pumps about 4,000 gallons of blood every day. Over the course of an average lifetime, it beats more than 3.5 billion times. 4,000 That’s half of the world populations. 4,000 gallon therapy pool
- 13. Respiratory System… Your lungs are the primary component of the respiratory system. Every time you inhale, oxygen makes its way to millions of tiny, sponge like sacs called alveoli that line the walls of your lungs. These sacs are surrounded by capillaries. Red blood cells in the capillaries absorb the oxygen, and then flow into the arterial system where the heart pumps them throughout your body
- 14. Respiratory System….. On the return trip, the red blood cells move through veins back into the capillaries, where they deposit carbon dioxide into the alveoli. The carbon dioxide is then expelled from your body when you breathe out. This amazing exchange takes place 25,000 times every day!
- 15. Your heart and lungs work together as a team to keep you alive. The least you can do is take good care of them. What do you or will you do to take care of your Heart and Lungs?
- 16. The larger holes are blood vessels. All the small partitions are air sacs alveoli The Bottom Pic is a smokers lung, they are very fragile Choose to Not smoke! Smoking Leads to…Heart disease, cancer, and respiratory illness are three of the leading causes of death in the United States.
- 17. Aerobic Exercise The purpose of aerobic exercise is to boost your heart rate and your oxygen intake over an extended period of physical activity. An aerobic exercise regimen has numerous benefits.
- 18. Your heart muscle will become stronger, and it won't have to work as hard when you are at rest. Your lung capacity will increase, Increased lung capacity will improve your stamina. You will lower your blood pressure, burn fat, and lose weight.
- 19. The key is to get your heart rate up and keep it there for the duration of your exercise period. A distance race would qualify, but a 100 yard dash would not.
- 20. The F.I.T.T. Principle F.I.T.T. is an acronym that stands for: Frequency - at least 3 to 5 sessions per week. Intensity - has to do with your target heart rate; which we will cover on the following screens. Type-refers to the form of aerobic activity you have chosen from the list. Time-the duration of your workout.
- 21. Student Activity • Take your Pulse (Wrist or Neck) • Count Beats for 15 sec. • Multiply by 4 = RHR What is your RHR (Resting Heart Rate)?
- 22. Target Heart Rate (THR) Activity Formula EXAMPLE 1. 220 - age = ? 220 – 29 years = 191 2. ? x .70 = THR 191 x .70 = 133 beats per min
- 23. In Summary….. • Cardiovascular Health is very Important, even Against Genetics, you can work to make your Heart Healthy • Work Smart not Hard, Remember to spot check for your Target Heart Rate • Don’t forget to Drink LOTS of water, and to warm up and cool down every time you exercise! :-]
