= = toc = = =Introduction= Red blood cells are crucial cells to have. These cells make up most of our blood. These cells are so important because they carry oxygen and energy for other cells. Without them we couldn't live. Sometimes your red blood cells don’t work and you get diseases.

=** How are Red Blood Cells Structured? **= Red blood cells are very important, because 99% of our blood is made of red blood cells. These cells are packed with **haemoglobin**. Haemoglobin are There are 4.6-5.8 million red blood cells per microliter of blood that is healthy. This cell is round like a donut and has no nucleus. Red blood cells are shaped like a donut for more surface area the oxygen sticks on the **haemoglobin**. When they have more surface area, they have more oxygen. Red blood cells do not have nuclei because without one they can carry more oxygen. They are two micrometers thick and 6-8 micrometers tall. This cell is so flexible that it can squeeze through blood vessels.

(Red blood cells) =** How Does a Red Blood Cell Function? **= It is very important for the red blood cell to function properly. Red blood cells carry antibodies. They also regulate your body temperature, to the normal number when you’re well. When you cut cut yourself the red blood cells form together to prevent blood loss. The amount of red blood cells you have is controlled by a protein called erythropoietin. Your red blood cells have a special protein called **hemoglobin**. These cells release enzyme carbonic anhydrate for water in the blood to form.

=** Sickle Cell Anemia **= Sickle Cell Anemia is a disease that affects your red blood cells. When you have this blood disorder, your blood cells become C shaped and can block blood vessels. This blood disorder is caused by a gene passed down in families. The effects of this are red blood cells die off in 10-20 days, which can cause a shortage in red blood cells. There are some ways to keep this under control such as blood transfusions, antibiotics and IV fluids. (Normal Cell and Sickle Cell)

Without these cells we wouldn't be able to function. Less than 1% of our blood isn't made up of red blood cells. If your red blood cells get sick, your body might not work properly. Without these cells, we couldn't live.
