Red+Blood+Cells+-+PZ

=__Introduction__= As I run out of breath running the mile, I realize that I should steady my breathing because my cells need oxygen and without cells their would be no living thing on this planet. When I learned just how much our bodies depend on our cells my jaw dropped to the floor and as much as I needed to breath, I just couldn't. Red blood cells have the most important job in your body, and no one could live without them. toc = __Chapter 1__: How are red blood cells are created and destroyed?= According to the book: Science Explorer *Human Biology and health, red blood cells die about every 3 months and you might be thinking,”Hey! How am I gonna live when all my red blood cells are dying?” Well, you live because your **bone marrow** creates about 2 million red blood cells per minute. Just as you perhaps may also be thinking “How can I fit so many red blood cells in my body when I create 2 million more every second?” As a result, you can fit so many red blood cells into your body because blood cells are microscopic and you need a specific microscope to see them.

= __Chapter 2:__ Red blood cells don’t change color, right? = Hmm, I wonder… If you haven’t guessed red blood cells are red of course, but red blood cells do actually change color. For instance, red blood cells circle inside your body going in the lungs retrieving oxygen, and giving it to cells that need it. Turning to when red blood cells carry oxygen, the turn bright red, when the blood cells pick up carbon that the other cells throw away, the red blood cells turn a deep darkened red. There is an irony paste that the red blood cells have that help them carry oxygen, this compound is **hemoglobin**. Specifically, **hemoglobin** not only helps the red blood cells grab oxygen from the lungs but it also gives it the red look! The **hemoglobin** carries the red blood cells around in the blood stream.

= __Chapter 3:__ ** What do red blood cells do and how do they do their job? **= Blood cells have a very important job in your body. Red blood cells circle your body in your blood stream and carry oxygen from your lungs to all your other cells and picking up carbon that other cells have thrown away. Everyone needs red blood cells, without them, you would die. Red blood cells have the complex job of **respiration. Respiration** is when the sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells, and the oxidation products, carbon dioxide and water, are given off.



= __Chapter 4:__ Do some people have a different amount of red blood cells in their body? Are all red blood cells the same? = Everyone has a different amount of red blood cells depending on their body and how it works and certain people have a disease called **sickle cell anemia**. These people struggle with things just because their red blood cells are misshapen and deformed. these cells cannot pick up oxygen because the doughnut hole is cut in half. Many people contain this disease, and it is very serious. Going back to **sickle cell anemia**, many people call it sickle cell disease, which it is a disease, but the proper name for it is actually **sickle cell anemia**.

= __Chapter 5:__ Shapes of a Red blood cells and why. = Red blood cells do look alot like doughnuts but they aren’t missing a doughnut hole. Red blood cells look like a bean bag chair that has just been sat in and the middle is smooshed inwards. Red blood cells use they’re doughnut hole to put the bubble of oxygen in and carry it around in your body! Something else that helps the cell pick up oxygen is the **hemoglobin** in your blood cells. **H****emoglobin** is an iron-like compound that helps grab the bubbles of oxygen because hemoglobin is very thick and sticky.

=__** Conclusion **__= Well now i will continue my mile jog and be sure to get more air and keep my breathing steady. Im also very glad I remembered how important oxygen is for my body especially now that i’m jogging again and using up the energy that my cells are giving me.

= __Vocabulary Words__  =

**Bone Marrow-** A thick sticky paste found in your bones. a chronic hereditary blood disease, occurring primarily among Africans or persons of African descent, in which abnormal hemoglobin causes red blood cells to become sickle-shaped and nonfunctional, characterized by enlarged spleen,chronic anemia, lethargy, weakness, joint pain,and blood clot formation.
 * Red Blood Cell- ** One of the cells of the blood, which in mammals are nucleated disks concave on both sides, contain hemoglobin, and carry oxygen to the cells and tissues and carbon dioxide back to the respiratory organs .
 * Respiration- ** the sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells, and the oxidation products, carbon dioxide and water, are given off.
 * Hemoglobin- ** the oxygen-carrying pigment of red blood cells that gives them their red color and serves to convey oxygen to the tissues
 * Sickle cell disease-**
