Red+Blood+Cells+-+AH

=INTRODUCTION= toc Did you know that the average adult has 20-30 trillion red blood cells? Red blood cells have a hard job. They pick up oxygen from your lungs and carry it around your body. Red blood cells are really important because we would not be able to live without them. Red blood cells give you energy as well because without them you would be tired all the time. Learning about what red blood cell do and what they look like, how they travel in the body, and how they die is important because without red blood cell we wouldn’t be alive so we’re lucky we have them! =WHAT DO RED BLOOD CELLS DO= Red blood cells take up o xygen in the lungs and Red Blood Cells are made by bone marrow like most of the most cells. Hemoglobin combines with oxygen and then makes the blood red.Our body needs oxygen to help our cells burn energy keep everything working in our bodies. Basically we can’t live without oxygen.

=WHERE DO RED BLOOD CELLS GO=

Your blood cells travel in a path that looks like a figure 8. In the first part of the figure 8 blood travels from heart to lungs and back to the heart. In the second loop the blood gets pumped throughout your body and back to the heart. When the blood cells leave your heart they pick up oxygen from the lungs and releases it as the blood travels through your capillaries. The blood carries the carbon dioxide that your body doesn’t need to your lungs where it’s released. Red Blood Cells mix hemoglobin and oxygen together which makes it bright red. Then leaves your heart through the aorta then gets brought to your cells through the capillaries Then the hemoglobin pick up the oxygen and releases it through the capillaries then goes back to your heart through the veins and then to the rest of your body so you can breath out the carbon dioxide.

=HOW MANY RED BLOOD CELLS DIE= Mature blood cells don’t have a nuclei. Blood cells that don’t have a nucleus cant reproduce or repair itself. Mature blood cells live to about 120 days. Every second about 2 million blood cells die. But your bone marrow produces new blood cells at the same rate.

=WHY ARE RED BLOOD CELLS RED=

Red blood cells are bright red because of the thing inside it called hemoglobin. Hemoglobin is made up of the element iron which makes it a really good vehicle for transporting oxygen and carbon dioxide. As the blood passes through the lungs, oxygen molecules attach to the hemoglobin as if it was a magnet. When the blood is passing through the body tissue, the hemoglobin releases the oxygen in the cells. The empty hemoglobin then bonds with the tissues carbon dioxide or the other waste gases sending it away.

=CONCLUSION=

All the information about red blood cells is fascinating .Learning how they work and take oxygen to your cells from your lungs so your body can function was interesting. Also how they help you live your everyday life.So now I know to be thankful for red blood cells.
