Keeping the Circulary System Healthy      posted 01-13-2012
It is important to keep your circulatory system working at its best. Your
heart pumps blood to every part of your body. It travels through
thousands of miles of blood vessels! Blood carries oxygen from your
lungs. If there is a problem with your blood, your heart, or your blood
vessels, your whole body can suffer. If you don't get enough oxygen to
your brain, you might not be able to think clearly. If your stomach isn't
getting enough oxygen, it might be hard for you to digest your food. If
there is a problem with one of your blood vessels, blood could stop
flowing to a part of your body. Without it, those cells could die.
What can you do to keep your circulatory system healthy? You can
make sure that you are getting plenty of exercise. When you exercise,
you heart beats faster. This makes your heart stronger. Your heart is a muscle. Just like the muscles in your arms
and legs, your heart gets bigger and stronger the more that you use it. Exercise also helps to keep your blood
vessels working properly. Go outside and play! Ride your bicycle. Go for a swim. Your body will thank you!
Eat healthy foods. They will keep your circulatory system healthy. Iron-rich foods like beans, whole-grain breads
and cereals, red meat, and green vegetables are good for your blood. Try to avoid fatty foods, especially fried foods
and foods that contain a type of fat called trans fat. Eating too much fat can cause fat to build up in your blood
vessels. This could cause a heart attack. Eating too much sugar can also be unhealthy. It causes inflammation, or
swelling, inside your body, even in your blood vessels. One final thing that you can do to keep your circulatory
system healthy is easy. Do not smoke. Smoking puts many dangerous chemicals in your body. It harms your blood
vessels and heart. It also puts unhealthy gases into your blood. Your cells will get less oxygen. Saying no to
smoking is the easiest way to do something good for your body.
Keeping Your Circulatory System Healthy
Questions

1. Which of the following is NOT a part of the circulatory system?
A. stomach
B. blood vessels
C. blood
D. heart

2. Exercise helps to keep your heart healthy because ______.
A. your heart gets stronger when it beats faster
B. your heart pumps less blood when you exercise
C. you make new blood vessels when you exercise
D. all of the above

3. Beans and green vegetables are a good source of ______, which is good for your blood.
A. oxygen
B. sodium
C. vitamin C
D. iron

4. Explain how a problem with your circulatory system could affect your brain.

5. What is one thing that you should not do in order to keep your circulatory system healthy?

6. Name two foods that you should eat and two foods that you should not eat in order to keep your circulatory system healthy. Explain why each food is healthy or unhealthy.

7. Exercise is good for your heart. What is your favorite way to exercise? Explain what you like about it.



Donating Blood      posted 01-05-2012
Donating Blood
By Cindy Grigg

A blood bank is a place where blood is stored for emergency use. In the United States about every two seconds, someone needs blood. That's over 43,000 people every DAY. Not long ago, people with a bad wound might have bled to death. Today, blood is donated by people. The donated blood is stored in blood banks to keep it safe for emergency use.

To donate blood, a person must be 17 years old and weigh at least 110
pounds. Adults have about 10 pints of blood in their bodies. When blood is donated, about one pint is taken. The process takes about 10 minutes. With the paperwork and recovery time afterwards, a person is usually in and out of the donation center in 45 minutes to one hour. January is National Volunteer Blood Donor Month.

One pint of blood can save up to three lives. A pint of blood can be separated into its different parts: red blood cells, plasma, and platelets. Donated blood can be given to a person as whole blood. Or each part can be given to three different people.

Red blood cells contain iron, and they carry oxygen in the blood. Platelets help blood to clot. Platelets are needed by people with leukemia and other cancers or patients having surgery. Plasma is a mixture of water, proteins, and salts. Plasma is needed to transport the other blood parts to all the body's cells. Plasma makes up more than half of the volume of blood.

Plasma can be frozen and used up to a year later. Red blood cells can be stored for 42 days. Platelets can only be
stored for 5 days. The American Red Cross urges people to donate blood so that many lives can be saved.

6. The author's main purpose for writing this story was to ______.
A. inform B. persuade C. express personal feelings D. entertain


Homework:

Do you know anyone who has received a blood donation? If so, ask this person how he or she feels about the person who donated the blood.

What would the person who received the blood like to say to the person whodonated it? If you don't know anyone who has received blood, write a dialog that you think might take place
between these two people.

Circulatory System
By Sharon Fabian

Blood circulates through your body all the time through a complicated system of large and small pathways. Your heart pumps day and night to transport the blood on its nonstop journey. This is your circulatory system, and it is in constant motion for a very good reason. Your circulatory system is like the freight train that delivers essential supplies to wherever they are needed in your body.

As blood travels to all parts of your body, it delivers food and oxygen to your cells. It removes carbon dioxide and other waste materials. Along the way, it also helps to regulate your body temperature.

The center of your circulatory system is your heart. It is a hollow muscle with two side-by-side pumps. When you are resting, your heart pumps about 70 times each minute. When you are exercising, it pumps even more. The pump on the right side sends a supply of blood to your lungs. The pump on the left side sends blood to all other parts of your body.

Another part of the system is blood vessels, the rubbery tubes that carry the blood from place to place. The three types of blood vessels are arteries, veins, and capillaries. Arteries carry blood from the heart; the main one is the aorta. Veins carry blood to the heart; the two main ones are called the vena cava. Capillaries are very tiny blood vessels that connect arteries to veins.

The third part of the circulatory system is the blood itself. Blood is made up of a liquid called plasma and three types of particles called red cells, white cells, and platelets. An average sized adult has about 5quarts of blood in his body. A child who weighs 80 pounds has about 2 1/2 quarts of blood.

The circulatory system does its job by working together with other body systems. It works with your respiratory system to deliver oxygen. After your lungs take in a good breath of air, the oxygen passes into your blood stream. The blood travels to your heart, where it is pumped out the left side, through your aorta, to all parts of your body. Blood carries its supply of oxygen through your arteries, then through smaller capillaries, and finally delivers it through the capillary walls to wherever it is needed. Next, carbon dioxide, which you don't need, comes into the capillaries, passing right through the capillary walls just like the oxygen did. It flows through little capillaries, then through larger veins back to the heart through a main vein, the vena cava. The right side of your heart pumps this supply of blood, with its cargo of carbon dioxide, to your lungs, and you breathe out. One journey is finished!

Your circulatory system works with your digestive system in much the same way that it works with your respiratory system. It carries digested food to everywhere it is needed. Food enters the blood stream the same way that oxygen does, right through the wall! Digested food passes through the wall from your small intestine into your capillaries. Your blood stream carries it on a complete path through your body, with a stopover at your liver. It delivers the nutrients, the good parts of the food, to the right places, and carries the waste products on to other places so they can be disposed of.

Blood helps regulate your temperature too. When the weather is hot, lots of blood flows to your skin where it can release heat from inside your body. In cold weather, less blood flows to your skin, to keep more of your heat inside. Your heart, blood vessels, and blood make up a system that can do all kinds of useful things! In fact, they make up the best transportation system ever invented -- your circulatory system.

Caption: Frog blood cells; the white blood cells are the round,
dark ones in the center of the picture.

Red blood cells give your blood its red color. They carry oxygen
from your lungs to all of the cells in your body. However, there is
more to your blood than just red blood cells. More than half of your
blood is made up of a liquid called plasma. It is mostly water, but it isvery important. Plasma helps your blood to flow. It allows your heart to pump your blood through your blood vessels. Red blood cells make up most of the remaining part of your blood, but there are other
important blood components. One of these is white blood cells.

White blood cells may seem a little out of place in your blood.
They have little in common with red blood cells. Their job has nothing to do with the heart or blood vessels. White blood cells are like soldiers. Their job is to protect you from invaders. White blood cells fight germs that try to enter your body. Germs can get into your body through the air that you breathe and through the things that you eat or drink. They can also get into your body through a cut on your skin. White blood cells are always looking out for germs. If they find a germ (or many germs), they can call
for help and more white blood cells will come to help. If there is an accident and you have a cut, white blood cells can also help to prevent germs from getting inside your body. They move quickly to the area that is hurt. They help keep the area clean, help your body to heal, and kill germs.

Normally, there are not very many white blood cells in your blood. If you need them, your body can make more. If you get a small cut on your knee, you will need a few more white blood cells to help the cut heal and to kill germs. If you get sick with the flu, you will need a lot more white blood cells. After the threat has passed,
some white blood cells can remember what the invader looked like. These white blood cells can react very quickly if that type of germ ever returns. They can act so quickly that they can kill the germ before it can makeyou sick!

White Blood Cells
Circle the correct answer for each question.(10 points each)

1. ______ makes up more than half of your blood.
A. Red blood cells B. White blood cells C. Plasma D. Platelet

2. White blood cells ______.
A. carry oxygen to your cells B. fight germs
C. help your blood flow D. all of the above

3. What is the job of a white blood cell?

4. Your body makes more white blood cells ______.
A. when you have a cut B. when you get sick
C. when you need them D. all of the above

5. What can some white blood cells do that protects you from getting sick from the same type of germ a second time?

6. Doctors can count the number of white blood cells in your blood to help them find out what is wrong with apatient. What does it mean if a patient has a large number of white blood cells in their blood?
(20 points)

7. What does it mean if there are a small number of white blood cells in their blood? (20 points)

White Blood Cells
By Jennifer Kenny

White blood cells are one of the four main parts of blood. The other parts are the red blood cells, platelets, and plasma. There are different kinds of white blood cells, but they all have an important job. Do you know what that job is? White blood cells defend the body from infection and disease.

Some white blood cells go to the places in your body where you have a cut. They attack any bacteria that enteryour blood to stop them from spreading throughout your body.

Some bacteria and viruses that enter your body carry chemicals called antigens. Your white blood cells make their
own chemicals called antibodies, which will attach themselves to these antigens so that the poisons from the bacteria or viruses become harmless. Do you know how amazing these cells are? Well, the antibodies that your white blood cells produce only attack the antigen for which it was made. For example, an antibody for the chickenpox virus will only attack the chicken pox virus, not the measles virus. Even more amazing is that the white blood
cells in your body remember how to make the antibody in case the germ ever enters your body again!

White blood cells are larger than red blood cells. However, there are fewer white blood cells in the human bodythan red blood cells. Unlike red blood cells, white blood cells can move on their own. They move by changing their shape. They can also change their shape to swallow up invaders.

White blood cells aren't really white. They don't really have a color and they sort of look like jellylike blobs. Don't
let that fool you, though. These colorless, jellylike blobs are like soldiers protecting our bodies by attacking and
destroying invaders!
