What Is The Function Red Blood Cells – Blood is the special fluid that flows through your body all the time. It does many things to keep your body working, like carrying oxygen around your body. Blood cancers and blood diseases can prevent the blood from doing its important work. Health professionals have many ways to treat blood cancers and blood disorders.
Blood is mostly water but contains cells and proteins. Blood has four components: red blood cells (bottom right), white blood cells, platelets (middle right) and plasma (top right).

Blood has four components: red blood cells, white blood cells, platelets and plasma. Each part has a specific and important function, from carrying oxygen to removing waste.
Your blood also acts as a kind of health barometer. Abnormal blood test results can be the first sign of changes that may indicate a serious illness. This topic focuses on how blood works and conditions that affect blood health.

Blood has four parts. Red blood cells and plasma make up most of your blood. White blood cells and platelets, sometimes called platelets, make up less than 1% of your blood.
Red Blood Cells: Function And Structure
Red blood cells (erythrocytes) make up 45% of your blood. They carry oxygen throughout your body. They also help eliminate waste from your body. These cells:
Your white blood cells (leukocytes) make up less than 1% of your blood and are part of your immune system. When invaders such as viruses or cancer cells attack, your white blood cells move quickly to find and destroy them. White blood cells can travel through the capillaries into your body. There are five types of white blood cells:
Your platelets (thrombocytes) are the first to appear whenever your blood vessels are damaged and bleed. Platelets control bleeding by forming blood clots that seal off damaged blood vessels so you don’t lose too much blood. Platelets:
Your blood cells and platelets float in your plasma. Plasma is the purple liquid that makes up 55% of your blood. Plasma is the main component of your blood, covering many bases as it works to keep your body functioning. Some plasma functions include:

There are four types of blood. Different types depend on whether the blood contains certain antigens. Antigens are what cause the immune system to react.
Blood flows throughout your body. It starts in your bone marrow, which contains stem cells. Stem cells produce trillions of cells, including blood cells. Blood cells develop and grow in your bone marrow before they enter your blood vessels. Blood represents about 8% of your body weight.
Blood cancers, blood diseases and heart diseases often affect the blood. Blood cancers affect how your body produces blood cells. A blood disorder causes your blood to stop working. Atherosclerosis is a heart disease that affects the blood flow. In general, blood cancer and blood disease have a greater impact on blood health than atherosclerosis.
Blood cancer occurs when something disrupts the way your body makes blood cells. If you have blood cancer, abnormal blood cells outnumber normal blood cells. There are three types of blood cancer:
Solution: Red Blood Cells And White Blood Cells Notes
A blood disorder is a non-cancerous condition that prevents parts of your blood from doing their job. Blood problems include anemias, blood clotting disorders and bleeding disorders.
Some blood problems may not cause symptoms or require treatment. Others are chronic (life-long) illnesses that require treatment but will not affect how long you will live. There are also blood diseases which are serious and life-threatening diseases.
Anemia is a rare and common blood disorder. It happens when you don’t have enough red blood cells. Sometimes people inherit anemia, but they can also acquire or develop it. There are many types of anemia. Some common anemias include:
Bleeding disorders affect your platelets or clotting factors (coagulation factors). Clotting agents are proteins in your blood that help your platelets control bleeding. You may develop a blood clotting disorder (acquired blood problem) or inherit a genetic mutation that causes poor blood clotting.

Mutations in the prothrombin gene and Factor V Leiden syndrome are examples of inherited bleeding disorders. Antiphospholipid syndrome (APS) and disseminated intravascular coagulation (DIC) are examples of acquired blood clotting disorders.
Blood clots occur when your blood does not clot properly, causing you to bleed more than usual. Von Willebrand disease is the most common bleeding disorder in the US Hemophilia, a rare inherited condition, is another example of a bleeding disorder.
Your blood is a precious resource, always take care of your body so that it works as well as it should. Your blood delivers oxygen to your cells so they can produce energy. It helps the immune system protect your body from invaders. Blood also controls how much you bleed when you are injured. Although you can take care of your blood, you cannot avoid the diseases that affect it. Fortunately, medical professionals can treat the most serious blood conditions, including blood cancers and blood disorders. Erythrocytes (red blood cells or RBCs) are a myeloid system of specialized cells that perform important role in the circulatory system. They are highly specialized, have a biconcave shape, and are rich in red color called hemoglobin. With a large surface and a volume without many parts of the body, these selfless messengers through their significant changes in red blood cell deformation make the change of breathing air such as oxygen and carbon dioxide.
Erythrocytes are a special type of blood cell that is characterized by the lack of cell division ability and the presence of hemoglobin (a special cell that contains iron). Some important things to know about erythrocytes are:
Red Blood Cell Membrane
An erythrocyte is a blood cell with a cytoplasm rich in hemoglobin whose function is to transport the respiratory gases, mainly oxygen and carbon dioxide. Oxygen molecules enter the erythrocytes from the air that comes from the respiratory system (such as the lungs of terrestrial vertebrates or the gills of fish). Erythrocytes deliver oxygen (from the circulatory system) to hypoxic tissues in need of oxygenation. With the release of oxygen molecules, many carbon dioxide molecules (from the tissues that diffuse into the blood plasma) enter the erythrocytes to be transported and then released to the outside through the respiratory system.
Most vertebrates have red blood cells that stay warm. However, in mammals including humans, mature red blood cells are biconcave and convex. In humans, carbon dioxide molecules are released from erythrocytes as bicarbonate ions into the plasma and converted back to carbon dioxide when they reach the alveolar spaces in the lungs to expire. Crocodile fish of the Channichthyidae family are the only vertebrates that do not have erythrocytes that obtain oxygen from their oxygen-rich aquatic habitats through migration.
The cytoplasm of mature erythrocytes has the presence of organelles. When we see erythrocytes under the microscope after the blood sample is stained with hematoxylin and eosin (H&E), we see them as red blood cells. One important thing we need to know here is that hematoxylin alone does not stain erythrocytes as hematoxylin stains the nucleus of cells that are not present in erythrocytes.
Erythropoiesis is the process of production of erythrocytes that occurs in the red bone marrow as “part of hematopoiesis”. Initially, hematopoiesis produces erythroid cells known as CFU-E (Colony Forming Unit – Erythroid), which initiate the main erythropoiesis process under the influence of the hormone erythropoietin. These CFU-E cells are deposited into erythroid islets in the bone marrow and undergo further differentiation to produce mature erythrocytes. During the various stages, several generations of cells are produced, including proerythroblasts, erythroblasts, reticulocytes, and finally, erythrocytes. In each generation, the cells histologically closely resemble erythrocytes.

) to move into the body. Oxygen binds to hemoglobin in the lungs. This leads to the formation of tight junctions that allow erythrocytes to transport O
The bicarbonate ion is more soluble and can be readily transported to the blood plasma. Some bicarbonate ions remain in the erythrocytes, while others are transported to the plasma. As erythrocytes reach the lungs, carbonic anhydrase converts bicarbonate ions to CO

Erythrocytes can inadvertently transfer carbon monoxide (CO) when it binds to hemoglobin, leading to the ability to carry oxygen to the body.
How Is The Structure Of Red Blood Cells Compatible With Their Function?
Carbon monoxide poisoning occurs when too much CO binds to hemoglobin. This disrupts the normal oxygen-carrying function of erythrocytes.
Hemoglobin has a higher affinity for carbon monoxide (CO) compared to oxygen. This leads to the formation of a stable compound known as carboxyhemoglobin.
The presence of carboxyhemoglobin in erythrocytes can cause serious health problems, because it prevents normal oxygen delivery and can cause CO poisoning.
Everyone is trying to understand the overall health of the body in the last 3-4 months,
