Red blood cell
Red blood cells, also known as RBCs, red cells, red blood corpuscles, haematids, erythroid cells or erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen to the body tissues—via blood flow through the circulatory system. RBCs take up oxygen in the lungs, or gills of fish, and release it into tissues while squeezing through the body's capillaries.
Hemoglobin
Hemoglobin; also spelled haemoglobin and abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of all vertebrates (with the exception of the fish family Channichthyidae) as well as the tissues of some invertebrates. Hemoglobin in the blood …
What is the life cycle of erythrocytes?
There are a total of 20 to 30 trillion erythrocytes in the human body and to maintain the homeostasis about 2.5 million of those erythrocytes are destroyed and replace every second. The life cycle of an erythrocyte is 120 days.
What is the life span of erythrocytes?
Thus, both are critical for the synthesis of new cells, including erythrocytes. Erythrocytes live up to 120 days in the circulation, after which the worn-out cells are removed by a type of myeloid phagocytic cell called a macrophage, located primarily within the bone marrow, liver, and spleen.
What causes high erythrocytes?
high erythrocytes or high red blood cell count is triggered by reasons like reduced oxygen levels, kidney issues, performance enhancing drugs; etc. low oxygen levels can make the body increase red blood cell production for cases like heart failures, congenital heart conditions,smoking, copd, pulmonary fibrosis, sleep apnea, hemoglobinopathy …
What causes elevated erythrocytes?

Are erythrocytes and hemoglobin the same thing?
Red blood cells (RBC) are made in the bone marrow and contain hemoglobin, a protein that carries oxygen to the tissues in the body. These cells are also known as erythrocytes.
What do you mean by erythrocyte?
A type of blood cell that is made in the bone marrow and found in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.
What is the role of erythrocytes?
Erythrocytes, red blood cells (RBC), are the functional component of blood responsible for the transportation of gases and nutrients throughout the human body. Their unique shape and composition allow for these specialized cells to carry out their essential functions.
What is your hemoglobin?
Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs. If a hemoglobin test reveals that your hemoglobin level is lower than normal, it means you have a low red blood cell count (anemia).
What happens when erythrocyte is low?
Anemia is a condition in which you lack enough healthy red blood cells to carry adequate oxygen to your body's tissues. Having anemia, also referred to as low hemoglobin, can make you feel tired and weak. There are many forms of anemia, each with its own cause.
What is normal erythrocyte level?
A normal range in adults is generally considered to be 4.35 to 5.65 million red blood cells per microliter (mcL) of blood for men and 3.92 to 5.13 million red blood cells per mcL of blood for women.

What is an example of erythrocyte?
red blood cell, also called erythrocyte, cellular component of blood, millions of which in the circulation of vertebrates give the blood its characteristic colour and carry oxygen from the lungs to the tissues. The mature human red blood cell is small, round, and biconcave; it appears dumbbell-shaped in profile.
What does high erythrocyte mean?
What does it mean when your red blood cell count is high? If you have a high red blood cell count, then you have something called erythrocytosis. This makes your blood thicker than it should be, and it could increase your risk for blood clots.
What are the characteristics of erythrocytes?
Erythrocytes have a consistent diameter of 7-8 µm, making them the perfect ‘histologic rulers’ during routine examinations. However, they have an atypical structure compared to the majority of human body cells. First of all, erythrocytes have a biconcave shape, which resembles a donut. This means that their periphery is thicker than their central part. This feature maximizes the total surface of the cell membrane, facilitating gas exchange and transport. In addition, erythrocytes do not have a nucleus ( anuclear) or any other intracellular organelles, as they are all lost during erythropoiesis. The only two major structures left are the cytoplasm which is enclosed by a surrounding cell membrane.
What is the shape of erythrocytes?
First of all, erythrocytes have a biconcave shape, which resembles a donut. This means that their periphery is thicker than their central part. This feature maximizes the total surface of the cell membrane, facilitating gas exchange and transport.
How long do erythrocytes live?
These mature RBCs are released into the bloodstream, where they survive between 100 to 120 days. As you can see, erythrocytes describe the state of your health for the past 3 months, so they can’t be fooled easily! This is the basis for the glycated hemoglobin (HbA1c) test performed by diabetics every 3 months to check their blood glucose levels. After 120 days, old RBCs are recycled by the macrophages of the spleen, liver, bone marrow and lymph nodes (reticuloendothelial system).
What are the different types of anemia?
Anemias can be classified into various types, depending on their causes: 1 Hemolytic anemia - caused by increased degradation or destruction of erythrocytes. 2 Sideropenic anemia, also known as iron deficiency anemia. 3 Megaloblastic anemia is caused by deficiency of folate and/or vitamin B12. They are necessary for differentiation of erythrocyte precursors. 4 Aplastic anemia is due to aplasia (destruction) of the red bone marrow. It can happen during chemotherapy.
What is the role of erythrocytes in the lungs?
The main role of erythrocytes is transportation and exchange of gases (oxygen, carbon dioxide) between lungs and tissues. Here’s how this happens in real time: In lung capillaries, hemoglobin binds the inhaled oxygen, forming oxyhemoglobin. This substance gives erythrocytes, and hence arterial blood, a bright red colour.
What is the cytoplasm of RBCs?
Cytoplasm. The cytoplasm of RBCs is filled with hemoglobin, a protein that reversibly binds and transports oxygen and carbon dioxide. The acidophilia of hemoglobin makes erythrocytes to stain intensely red with eosin on tissue samples stained with hematoxylin and eosin (H&E).
How are RBCs produced?
They are produced in the red bone marrow by a process called erythropoiesis. During this process, stem cell derived erythroid precursors undergo a series of morphological changes to become mature erythrocytes. These mature RBCs are released into the bloodstream, where they survive between 100 to 120 days.

Why are erythrocytes high?
High erythrocytes or high red blood cell count is triggered by reasons like reduced oxygen levels, kidney issues, performance enhancing drugs; etc. Low oxygen levels can make the body increase red blood cell production for cases like heart failures, congenital heart conditions,smoking, COPD, pulmonary fibrosis, sleep apnea, hemoglobinopathy (condition that impairs oxygen transmission capacity of RBCs) and high altitudes. Dehydration, marked by a condition in which the liquid portion of the blood or plasma is reduced, results in the concentration of red blood cell count (even though the count remains the same).
Why is erythrocyte count important?
The test is also referred to as an erythrocyte count. The test is vital as erythrocytes contain hemoglobin, which transports oxygen to various tissues. The number of red blood cells determines how much oxygen tissues will receive. Oxygen is vital for proper functionality of body tissues.
Why is my blood red?
Erythrocytes are red in color. They are made up of a protein known as hemoglobin, which has red iron. This red iron explains why our blood is red in color. Red blood cells are round in shape. When erythrocytes are normal, they are doughnuts shaped with holes at the center. Hemoglobin gives these cells the round shape, which increases surface area for absorption of oxygen allowing them to transport more oxygen.
Why do carbon dioxide and oxygen bind to hemoglobin?
This takes place to avoid interference with oxygen transport.
What is the respiratory pigment in the body that binds to carbon dioxide and oxygen allowing them to be transported in?
This offers more space for storage of hemoglobin. Hemoglobin is the respiratory pigment in the body that binds to carbon dioxide and oxygen allowing them to be transported in and out of tissues. Hemoglobin has iron, which combines with oxygen giving blood the red color.
What is the normal range of erythrocytes?
However, the normal range of RBCs count in adults is 700,000 to 5.2 million RBCs per mcl in men and for women, the normal range is considered to be between 500,000 and 4.6 million RBCs per microliter.

What is the function of red blood cells?
The main function of RBC is to transport the oxygen by hemoglobin, which is located inside it, to the different parts of the body. Once the oxygen is delivered ...
What is the role of the RBC in the transport of oxygen?
Once the oxygen is delivered to the parts of the body, the RBC collects carbon dioxide and takes it to the lungs. Hemoglobin’s key function is the facilitation of gases, oxygen and carbon dioxide as the transportation is happening. So typically, the hemoglobin holds the gases while the RBC is carrying the hemoglobin and transporting it to ...
What is the major component of RBC?
RBC has many components and the major one is the hemoglobin. The next time you encounter these two terms, always remember that these two things cooperate with each other in transporting the oxygen from the lungs to the other tissues in the body, and after transporting the oxygen, they gather carbon dioxide back to the lungs.
What is the most abundant type of blood cell?
Red blood cells are a very essential part of our blood, and as a matter of fact it is the most plentiful type of blood cells in our body. Hemoglobin (or Hgb) is a protein that is found inside a red blood cell and is responsible for carrying the oxygen coming from the lungs to the different parts of the body.
Is hemoglobin the same as red blood cells?
So basically, red blood cells and hemoglobin are somewhat connected with each other, but are not exactly the same.
Is hemoglobin a component of RBC?
The tip for not getting confused with RBC and hemoglobin is that you should always bear in mind that hemoglobin is just a component of RBC. RBC has many components and the major one is the hemoglobin. Author. Recent Posts.
Why is my hemoglobin low?
Thalassemia. A low hemoglobin count can also be due to blood loss, which can occur because of: Bleeding in your digestive tract , such as from ulcers, cancers or hemorrhoids. Frequent blood donation.
What causes a person to have fewer red blood cells?
Diseases and conditions that cause your body to produce fewer red blood cells than normal include: Aplastic anemia. Cancer. Certain medications, such as antiretroviral drugs for HIV infection and chemotherapy drugs for cancer and other conditions. Chronic kidney disease.
Is low hemoglobin count normal?
A slightly low hemoglobin count isn't always a sign of illness — it can be normal for some people. Women with menstrual periods and pregnant women commonly have low hemoglobin counts.
What is hemoglobin?
Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs.
What is the red color of blood?
The iron contained in hemoglobin is also responsible for the red color of blood. Hemoglobin also plays an important role in maintaining the shape of the red blood cells. In their natural shape, red blood cells are round with narrow centers resembling a donut without a hole in the middle.
How is hemoglobin measured?
Hemoglobin is usually measured as a part of the routine complete blood count ( CBC) test from a blood sample.
What are normal hemoglobin values?
The hemoglobin level is expressed as the amount of hemoglobin in grams (gm) per deciliter (dL) of whole blood, a deciliter being 100 milliliters.
What does a low hemoglobin level mean?
A low hemoglobin level is referred to as anemia or low red blood count. A lower than a normal number of red blood cells is referred to as anemia and hemoglobin levels reflect this number. There are many reasons (causes) for anemia.
What is sickle cell disease?
Sickle cell disease is a genetic condition in which the quality of hemoglobin is defective. This condition can cause abnormal hemoglobin that can result in abnormally-shaped (sickled) red blood cells (see illustration). These abnormal red blood cells cannot easily pass through small blood vessels leading to inadequate oxygen for the tissues of the body.
What is the hemoglobin A1c test?
Hemoglobin A1c or glycosylated hemoglobin is a rough indication of blood sugar control in people with diabetes mellitus over the preceding 3 months. As more glucose (blood sugar) circulates in the blood on a daily basis, more glucose is bound to the circulating hemoglobin. Normal hemoglobin A1c levels range between 4% to 5.9%. As this number reaches 6% or greater, it signifies poorer diabetes control.
