Blood is the liquid connective tissue and also it plays a very an essential role in the human being body. There are four primary materials of blood, which room red blood cells, white blood cells, platelets and plasma. Plasma makes up roughly 55 % that the human being blood in the body.

Difference between Red Blood Cells and White Blood Cells

The far-ranging differences in between red blood cells and also white blood cells room as follows:


RBC – Red Blood CellsWBC – White Blood Cells
Red blood cells are referred to as Erythrocytes.White Blood cell are referred to as Leucocytes or Leukocytes.
RBCs have actually a bi-concave key shapeWBCs have an rarely often, rarely shape.
Size varies from 6 – 8 µm in diameter.Size different from 12 – 17 µm in diameter.
The lifespan of RBC is around 120 days.The expectancy of WBC is approximately 12-20 days after which lock are destroyed in the lymphatic system
Red blood cells execute not have a cell nucleus on maturity.WBCs are defined by the presence of a large main nucleus.
Due come the visibility of haemoglobin, this cells show up red in colour.These cells are colourless, together they do not have any pigment.
Only one kind of RBC exists.Different types of WBCs are discovered in the blood such as neutrophils, B lymphocytes, T lymphocytes, monocytes, basophils, eosinophils.
They aid in the move of respiratory tract gases to various parts of the human being bodyThey help in creating antibodies come fight against disease-causing microbes.
RBCs are produced in the red bone marrowThese cells are developed in the red bone marrow, lymph nodes, and spleen.
The components of red blood cells space haemoglobin.The materials of white blood cells are antibodies with the visibility of MHC (major histocompatibility complex) antigen cabinet markers.
These cells do up roughly 36-50% of person blood.They do up approximately 1% the the human blood.
RBC count: 5 million/ mm³ of blood.WBC count: 7000–8000/mm³ that blood.
The procedure of development of RBC is known as erythropoiesis.The procedure of formation of WBC is well-known as leukopoiesis.
These cell move in between the cardiovascular systems.These cell move in between the cardiovascular and also lymphatic systems.
Low count of RBCs results in Anaemia.Low counting of WBCs results in Leukopenia.

The Red blood cells are additionally called erythrocytes. RBCs keep the haemoglobin, i beg your pardon is a respiratory pigment that binds to oxygen or carbon dioxide molecules. This helps in the transportation of the oxygen to various tissues and organs that the person body. It also takes far the carbon-dioxide from various organs and tissues to it is in replenished in the lungs.

Haemoglobin is largely composed of iron, which combines through the oxygen, thus offering a red colour come the blood. It occupies 40-45% of the total volume that blood. The primary function of the RBCs is the transport of nutrients and also hormones throughout the human body.


The lifespan of RBC is 100-120 days. When their expectation is completed, castle are eliminated through the circulatory system. Once a human suffers from chronic diseases, the lifespan of RBCs is reduced.

The white blood cells are likewise called Leukocytes. These cells act together a defence system versus any infections in the human body. They create special kinds of proteins dubbed antibodies, which identify and also fight pathogens invading the human being body. These cells are classified additional as granulocytes and also agranulocytes.

The white blood cells contain clearly shows granule-like structures in the cell bodies, thus their surname Granulocytes. Top top the other hand, agranulocytes execute not possess these granule-like structures. The three kinds the granulocytes room neutrophils, basophils, and eosinophils. The two varieties of agranulocytes are lymphocytes and monocytes.

WBCs make up 1% the the full blood volume. They room colourless since they room devoid the haemoglobin.


The expectation of WBC is 12-20 days. After ~ that, they are ruined in the lymphatic system. The immature WBCs room released indigenous the bone marrow into the peripheral blood and also are dubbed bands or stabs. The expectancy of WBC transforms with age. For instance, a newborn baby has actually a high white blood cell counting in comparison come an adult. The count of WBC likewise changes v pregnancy. A pregnant woman has a very high white blood cell count contrasted to a woman who is no pregnant.

The blood is primarily connected in the transportation of oxygen and nutrients across the body. The is additionally responsible because that the regulation of human body temperature.


Red blood cells in a usual adult human have a lifespan of 100 come 120 days. However, diseases or illnesses can reason the expectation to be shortened drastically.


Leukocytes are likewise called white blood cells. They function to keep the body for sure from pathogens and infections.


The main function of white blood cell is to ensure the pathogenic particles or foreign substances that go into the body are quickly ruined by phagocytosis.


The typical lifespan that WBC is roughly 12 to 20 days. However, similar to the RBCs, the lifespan of WBCs have the right to be affected if the individual is sick. The count of WBC also changes v the period of the individual; because that instance, a child baby has comparatively an ext WBCs than an adult.


Red blood cells room disc-shaped and also biconcave; meanwhile, white blood cells carry out not have a identified shape.

There various varieties of white blood cells room neutrophils, B lymphocytes, T lymphocytes, monocytes, basophils and eosinophils


The red blood cells are developed in the bone marrow. However, it needs seven days come mature prior to being released right into the bloodstream.
