5. Blood Travel Through the Body
The droplet travels into smaller and smaller branches of arteries until it finally enter a blood vessel so tiny that it is naked to he eye. In this vessel, known as a Capillary, nutrients are exchanged for waste products.
Now that the blood has given up its Food and Oxygen, it must return to the heart to refuel. The droplet of blood leaves the capillary, and heads into a larger blood vessel called a Vein.

6. Blood Travel Through the Body
The blood makes its way through branches of veins until it finds itself in the largest vein found in the body. This vein has two separate entranceways into the heart. Blood in need of refueling coming from the head and arms enters the heart through the Superior Vena Cava. Blood in need of refueling coming from the legs enters the heart through the Inferior Vena Cava.
The Vena Cava’s pour blood lacking oxygen into which chamber of the heart? Atrium.

7. Vocabulary
Arteries- Blood vessels that carry blood away from the heart to other parts of the body.
Aorta- Largest blood vessel, carries oxygen rich blood away from the heart.
Veins- Blood vessels that carry blood from the body back to the heart.
Inferior Vena Cava- Largest vein, carries oxygen poor blood to the heart
Superior Vena Cava- Carries oxygen poor blood to the heart.

8. Vocabulary
Heart- The muscle that acts as the pump for the circulatory system.
Blood Pressure- The force of blood pushing against the blood vessel walls.
Respiratory System- Enables you to breathe.

10. Vocabulary Superior Vena Cava- Carries oxygen poor blood to the heart.

11. Finding Your Target Fitness Zone
1. Subtract your age from This will tell you your maximum heart rate.
2. Multiply your maximum heart rate x 60%. This number is your minimum heart rate for fitness to take place.
3. Multiply your maximum heart rate x 85%. This number is your maximum heart rate for fitness to take place.
4. Your target heart rate falls between your maximum heart rate and your minimum heart rate.

12. Example
220-11= 209
209 = Max Heart Rate
209 x .6= 125
125 = Minimum heart rate for fitness
209 x .85= 178
178 = Maximum heart rate for fitness
Target Heart Rate falls between:
