CIRCULATORY SYSTEM The Circulatory System is like the transportation system in your body. Veins, arteries, and capillaries carry blood to and from the heart to the rest of your body. The heart is the most important organ in this system, as it keeps the blood pumping throughout your body.

__Activity__ Stand up. Find your pulse by placing your thumb on your chin. Then, twist your hand so that your pointer finger and middle finger are touching your neck. In this area, you should be able to find your pulse. You may have to shift these two fingers accordingly to be able to find it.

Now that you have found your pulse, count how many times you feel it beat in thirty seconds. Write this number down.

Next, jump up and down or run in place for one minute. You should feel out of breath by the end of this...

Take your pulse again. Find it using the same method that is listed above. Write this number down.

Did you notice how much faster your pulse was? In order to keep up with your body when it is exerting physical exercise, your heart pumps faster! Blood circulates more quickly so that oxygen may be delivered to all parts of your body. Now... you may be asking, what does blood have to do with oxygen? Your blood is also an important part of the Circulatory System... it contains red blood cells, which deliver oxygen and remove carbon dioxide, white blood cells, which fight against bacteria and infections, and plasma. As you can see, blood is extremely important!

RESPIRATORY SYSTEM The Respiratory System is the system that allows you to breathe. Your lungs are the most important part of this system. Other important parts within this system are the trachea, or windpipe, bronchi and bronchioles, alveoli, and the larynx, or voice box. All of these parts play an important role in your body. __Activity__ Place your hand above your stomach, but below your chest. Now, take a deep breath in. Do you feel this expand? Breathe out. Again, you can feel the movement in this area of your body. This is air entering and leaving your body.... More specifically, oxygen is entering your body, and carbon dioxide is leaving your body. Check out this link for a better idea of what is happening with your Respiratory System!

Although this sounds gross, this is a necessary process that must take place! The Digestive System begins with your mouth... more specifically, your teeth, tongue, and saliva. Then comes your esophagus, which we normally associate with our throat. From the esophagus comes the stomach, where food is stored before it becomes broken down by chemicals in your body. After the stomach, the waste travels into your small intestine, liver, and large intestine. From the large intestine, the waste is able to leave your body. <span style="font-family: 'Times New Roman',Times,serif;">More information on the Digestive System can be found at the following website. <span style="font-family: 'Times New Roman',Times,serif;">Digestive System <span style="color: #008000; font-family: 'Times New Roman',Times,serif; font-size: 180%;">URINARY SYSTEM <span style="color: #000000; font-family: 'Times New Roman',Times,serif;">The Urinary System is another way that your body is able to get of waste. Important parts of the Urinary System include your kidneys, ureters, bladder, and urethra. The kidneys are extremely important! They decide what is waste and what isn't. This is where the urine is produced. From there, urine travels into two tubes (one from each kidney), titled the ureters. These carry the urine into your bladder, where it is stored until you are ready to use the bathroom. When you go to the bathroom, your urine travels from the bladder, through the ureter, and out of your body. <span style="color: #000000; font-family: 'Times New Roman',Times,serif;">To learn more about the Urinary System, visit the following website. <span style="color: #000000; font-family: 'Times New Roman',Times,serif;">Urinary System <span style="color: #000000; font-family: 'Times New Roman',Times,serif;">This information can also be found on my Prezi, as shown below. <span style="color: #000000; font-family: 'Times New Roman',Times,serif;">media type="custom" key="24520528"
