Red Blood Cells/ Corpuscles (RBC) are also called “Erythrocytes” while White Blood Cells/ Corpuscles (WBC) are also called “Leukocytes”.
Some of the differences between Red Blood Cells/ Corpuscles (RBC) and White Blood Cells/ Corpuscles (WBC) are as follows:
S.N. | Differences | Red Blood Cells/ Corpuscles (RBC) | White Blood Cells/ Corpuscles (WBC) |
---|---|---|---|
1 | Also called | Also called “Erythrocytes” | Also called “Leukocytes” |
2 | Origin | They are produced in red bone marrow. | Mostly bone marrow, also produced in lymph nodes, spleen, etc. |
3 | Nucleus | Nucleus Absent | Nucleus Present |
4 | Size | Smaller than WBCs, 7.5µm | Larger than RBCs, 15µm |
5 | Color | Filled with hemoglobin (Red) | Colorless, No Pigment |
6 | Production | 2 million RBCs per second | Fewer WBC than RBCs |
7 | Life Span | RBCs have an average lifespan of 120 days | WBCs live anywhere from a few days (5-21 days) |
8 | Number | 5 million RBCs in every cubic mm of blood | 3,000 – 7,000 WBCs in every cubic mm of blood |
9 | Number Increments | Number increases during exercises and high altitudes | Number increases during infection |
10 | Process of Formation | Formation of RBC is called “Erythropoiesis” | Formation of WBS is called “Leucopoiesis” |
11 | Shape | Circular, Biconcave | Rounded and Amoeboid, Irregular |
12 | Motility | Non-Motile | Generally Motile |
13 | Movement | Doesn’t leaves Blood Vessels | Come out of blood Capillaries |
14 | Rouleaux Formation | Form stacks called Rouleaux | Rouleaux formation absent |
15 | Types | One Type | Five Types |
16 | Circulatory system | Cardiovascular system | Cardiovascular and lymphatic systems. |
17 | Function | Transport of Respiratory Gases (Oxygen and Carbon Dioxide) | Defense Mechanisms |
people with sickle cell do not have a complete shaped RBC, what do they miss in their body
Are platelets considered as cells? How does it play its role
Platelets are the tiny fragments of special cells formed bone marrow.
Platelets helps in the coagulation of blood during wound or a cut.
The above difference contains well defined and explained points which helps me a lot
Thank you
What is the ratio between RBC and WBC?
600:1 is the ratio
Ratio of RBC:WBC=600:1
600RBCs for each WBCs and 40 platetes
Why does Red blood cells have a longer lifespan as compared to white blood cells though the red blood cells lose their nucleus but white blood cells do not?
The WBC palyes role in the immune system so most of them can’t live longer, because the attacked the antigen,s that comes to our body from the outside, in this immunity process can’t allow most of the WBC to live many days cause they become defected already.
Hello,
does WBC types are 5 or 6?
Lymphocytes, Monocytes , Granulocytes , Neutrophils , Eosinophils and Basophils
Am I wrong?
They are 5. Granulocytes is use to called Netrophil,basophil and eosinophil because they contains granules
WBC’s are of 5 types eosinophils, basophils and neutrophils are commonly called granulocytes because of their rough surface.
No there are 2 types of wbc…and these 2 types are divided into 2 and 3 types….so there are 5 types of wbc and lymphocytes and monocytes are granulocutes…
do size of rbc’s vary with the size of the person, so that thin and short person has smaller rbc and big person has bigger one
Hello,
Please try to compile some study material related to agriculture microbiology specially for ARS NET Preparation. It will help to various aspirants for preparation. Please, Its my request, because most of available books are misguiding with lot of errors. I appreciate your efforts being specific for topics.
Note that when the spleen has been removed, red blood cells will sometimes show a nucleus. And also in certain Hematologic disorders which affect the rigidity of the cell membrane. The nucleus is lost so that the RBC can pass through tiny blood vessels.
