Red+Blood+Cells+-+JR

=Introduction= You're running a race and you stop to take a deep breath. When you feel the oxygen going in and out of your body it hits the blood and it sparks up your body. It gives you so much energy for you to do extra laps in a race without getting tired quickly. Reb blood cells have Some athletes injected themselves with more red blood cells for them to get more energy. Without red blood cells you wouldn't be able to take those deep breathes while you're running.

toc =Function of Red Blood Cells= The red blood cell is important because it carries oxygen to our cells. When oxygen and glucose come together in a body cell they produce energy, carbon dioxide, and water. This gives us energy to stand, for exercise, and the blood to flow (“Blood”). If our cells didn't have energy then are body couldn't function and we would die. Red blood cells has special structures that help them do their job.

=Structures of Red Blood Cells= Hemoglobin is one of the most important structure of the blood cells. A protein that has iron and it looks like a pretzel and it gives red blood cells the color red. Also It helps oxygen stick to the red blood cell like a magnet it picks up oxygen from the lungs and releases it to through the capillaries and into other parts of the body.

=Blood Doping= Blood doping is a cheating method of improving athletes performance by using fake blood so they could boost the blood's ability to bring more oxygen to muscles. In a lot of ways blood doping increases the amount of hemoglobin in the blood. Hemoglobin is an oxygen-carrying protein in the blood. Increasing hemoglobin allows higher amounts of oxygen to reach and fuel an athlete's muscles. This can improve stamina and performance particularly in long-distance events such as running and cycling.

=Conclusion= Red blood cells are like the delivery truck of your body. Like a truck red blood cells pick up oxygen from the lungs and brings the oxygen to the body cells. this delivery truck also removes carbon dioxide as if it's garbage back to the lungs. Some athletes know how powerful blood is and choose to illegally inject themselves with it. Red blood cells may be small but mighty.
