Red blood cells are the most common type of blood cell. They carry and deliver oxygen to different parts of the body. You’ve probably seen a microscope image of these cells before – they’re usually flat with a round, red nucleus in the center.
There are six different types of red blood cells, each with a different function.
1. Erythrocytes: These are the most common type of red blood cell. They make up about 99% of all red blood cells. Their primary function is to carry oxygen to different parts of the body.
2. Basophils: These cells make up less than 1% of all red blood cells. They play a role in the immune response by releasing histamine and other chemicals that help fight infection.
3. Neutrophils: These cells make up around 50% of all white blood cells (the other type of blood cell). They’re important for fighting bacterial infections.
4. Lymphocytes: These cells make up around 25% of all white blood cells. They play a role in the immune response by producing antibodies that help fight infection.
5. Monocytes: These cells make up around 6% of all white blood cells. They play a role in the immune response by engulfing and destroying bacteria and other foreign particles.
6. Eosinophils: These cells make up around 2% of all white blood cells. They play a role in the immune response
Types of Red Blood Cells
There are three main types of red blood cells: erythrocytes, metarubricytes, and basophilic erythrocytes.

Erythrocytes are the most common type of red blood cell. They are responsible for carrying oxygen from the lungs to the rest of the body.
Metarubricytes are a type of red blood cell that helps to remove carbon dioxide from the body. They are found in higher concentrations in the liver and spleen.
Basophilic erythrocytes are a type of red blood cell that helps to fight infection. They are found in higher concentrations in the lymph nodes and bone marrow
What Causes Anemia?
Anemia can be caused by a variety of factors, including:
-Blood loss: This can occur due to heavy menstrual bleeding, gastrointestinal bleeding, or blood loss from injuries.
-Destruction of red blood cells: This can be caused by conditions such as hemolytic anemia, sickle cell anemia, or thalassemia.
-Dietary deficiencies: Anemia can be caused by a lack of iron, folate, or vitamin B12 in the diet.
-Chronic diseases: Conditions such as kidney disease or cancer can cause anemia.
How Is Anemia Diagnosed?
Anemia is typically diagnosed with a blood test called a complete blood count (CBC). This test measures the number of red blood cells in the blood. A low number of red blood cells indicates anemia.
Hemoglobin and Oxygen Enzymes
1. Hemoglobin and Oxygen Enzymes: The hemoglobin in red blood cells carries oxygen from the lungs to the rest of the body. The oxygen enzymes help the hemoglobin release oxygen into the tissues.
2. Carbonic Anhydrase: This enzyme helps to regulate the pH of the blood. It also helps to remove carbon dioxide from the blood.
3. NADH Dehydrogenase: This enzyme helps to produce energy in cells. It also helps to protect cells from damage.
4. SOD: This enzyme helps to protect cells from damage caused by free radicals.
5. Catalase: This enzyme helps to protect cells from damage caused by hydrogen peroxide.
6. GSH-Px: This enzyme helps to protect cells from damage caused by peroxides.
Red Blood Cells Functions
Red Blood Cells (RBCs) are the most common type of blood cell and they function to carry oxygen from the lungs to the body tissues. RBCs are filled with a protein called hemoglobin, which gives the cells their red color. Hemoglobin is responsible for carrying oxygen molecules.
RBCs are produced in the bone marrow and they have a lifespan of about 120 days. After they die, they are broken down and recycled by the body.
There are two main types of RBCs:
1. Erythrocytes: These are the most common type of RBCs and they make up about 95% of all RBCs in the body. They are small, round, and flat.

2. Leukocytes: These are less common than erythrocytes and they make up about 5% of all RBCs in the body. They are larger than erythrocytes and have a more irregular shape.
RBCs are important for delivering oxygen to the body tissues. Oxygen is necessary for the cells to create energy. Without oxygen, the cells would not be able to function properly and would eventually die.
In addition to carrying oxygen, RBCs also help to remove carbon dioxide from the body. Carbon dioxide is a waste product that is produced when the cells create energy. RBCs transport carbon dioxide from the body tissues back to the lungs where it is exhaled.
RBCs are also involved in immunity. They help to protect the body from infection by destroying harmful bacteria and viruses.
Conclusion
Red blood cells are an essential part of our bodies, and many different types play different roles. Knowing the different types of red blood cells and what they do can help us better understand how our bodies work and how to keep them healthy.
