Blood cells are the part of liquid connective tissue.
These cells are freely moving and have important function in body.
As you might have know, there are basically 3 types of cells in the blood like
- Red blood cells
- White blood cells
Of the three, red blood cells and white blood cell carry important critical functions in the body.
The number of cells of these types are also quite high.
Red vs White blood cells
Red blood cells are also called as corpuscles because of their shape. Further, unlike typical body cells, they lack nucleus and other cell organelles.
The key differences among red blood cells vs white blood cells relate to
- Numbers or concentration in blood
Red blood cells are involved in distribution of oxygen. They transport oxygen from lungs to all the tissues and cells of the body. Further, they also help carrying of carbon-dioxide from tissues and cells back to the lungs. Thus red blood cells are involved in gaseous exchange in the body. Enzyme acetylcholinesterase is present on the membranes of RBC.
White blood cells have a different role in the body. They help in protecting the body from infections and also help in body repair. They act as body defense system and keep it healthy. They recognize the foreign cells and destroy them. They produce anti-bodies against the foreign antigens and neutralize them. Further, the neutrophils and macrophages eat and kill the harmful microorganisms in the blood and tissues. Lysosomal enzymes are present in the WBC cells which help autophagy and foreign cell destruction.
Anatomical and Structures differences:
Red cells are disc shaped with biconcave surfaces. Where as white cells are polymorphic (multi shaped). Further, red cells lack nucleus while white cells are multi-nucleated. Red cells are very small in size while white cells are large.
Numbers or concentration in blood:
Red cells are quite very high in concentration or number. Due to their high concentration, the blood is red in color. White cells are comparatively low in number. But, when their concentration increases in blood cancer, the condition is called leukemia (leuk = white; aemia= blood).
Types and variation among the cells:
Red cells are of only one particular type. Where as the white blood cells are of 5 types as acidophils, basophils, neutrophils, lymphocytes and monocytes.
Diseases and disorders:
Both red and white cells can be cause of diseases. Decrease in red cells is called as anemia. While there is no effect of increase in red cell count.
On the other hand, white cells have disorder with both increase and decreased cell count. Increase in white cells is termed as leukemia or leukophilia. While, their decrease is termed as leukocytopenia or leukopenia.
