react when you run or jump up and down?
Does your heart beat the same way all the
time?

Labeling of The Heart
 M- Aorta
 B- Superior Vena Cava
 E- Right Ventricle
 I- Left Atrium
 H- Pulmonary Vein
 A- Right Atrium
 K- Left Ventricle
 G- Pulmonary Artery
 D- Valve
 C- Inferior Vena Cava
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.
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.
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.
 Lungs- Main organs of the respiratory system.
Vocabulary
 Valve- one-way opening from one chamber or blood
vessel to another, prevents the back-flow of blood.
 Septum- Wall of the heart, separates left side from
right.
 Aorta- Largest blood vessel, carries oxygen rich
blood to the body.
Vocabulary
 Superior Vena Cava- Carries oxygen poor blood
to the heart.
 Inferior Vena Cava- Carries oxygen poor blood to
the heart
Finding Your Target Fitness Zone
 1. Subtract your age from 220. 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.
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:
125-178
Smoking Aerobics
