White blood cells are the immunity cells that flow in the blood along with the red blood cells, platelets and plasma. The blood system only comprises 1% of WBCs. However, their impact on human health is immense. It helps in the prevention of several illnesses and diseases and it is defending a body against various viruses, bacteria, germs and other foreign objects that cause harm to the health. Needless to mention it is one of the most important units for survival. Five types of WBCs in total have their specific functions in protecting a body.

Types of White blood cells

White blood cells are the units of immunity that help in maintaining health by combating various kinds of bacteria, germs and viruses that cause harm to human health. These white blood cells are further classified into five different sub-sections: 

  • Neutrophils: It is the most abundant of the WBCs; it almost accumulates to half of the white blood cell population. These are the first cells to respond against the virus, bacteria and different kinds of germs that harm health. These cells also send out signals to other WBCs in the immunity system to act against the invading foreign body.
  • Eosinophils: This is an important unit of WBCs, which fight against foreign particles. Eosinophils are the key responders against parasitic infections.
  • Basophils add up to only 1% of the WBCs and they are responsible for their role in asthma. These units are also functional against the disease spreading pathogens
  • Lymphocytes: These are essential in forming the immunity system against foreign bodies and there are two types of lymphocytes: B-lymphocytes and T-lymphocytes, the first responsible for the production of antibodies that memories an infection and thus help in combating the same pathogen while the latter is responsible for directly killing the same invader. However, it can also memorizes the pathogen and prevents a further attack from the same type of pathogen
  • Monocytes comprising 5 to 12% of the WBCs help in cleaning dead blood cells. They also have the longest span among the rest of the units of WBCs

Leukocytes: discussion

Leukocytes are the white blood cells that help the body fight against germs and bacteria. These units are also called White blood cells and are produced in the bone marrow. These units lack haemoglobin, have one nucleus, and are capable of motility. Leukocytes are further subdivided into type’s granulocytes and agranulocytes, the first contains granules in their cytoplasm and the latter lacks the presence of the same in their cytoplasm. 

Functions of WBCS

Functions of WBCs includes combating different kinds of virus, bacteria, germs and different kinds of pathogens.

WBCs

Functions

Monocytes

These units help in the process of cleaning the blood system by getting rid of the dead blood cells

Lymphocytes

These units come in two forms B- Lymphocytes and T-Lymphocytes. The former helps in memorising the pathogens and helps in forming various kinds of vaccines. T-lymphocytes directly kill the bacteria on its second onslaught, they also memorise the pathogens to prevent its breach the second time. 

Neutrophils 

These units are responsible for killing and digesting bacteria and fungi. These are the first responders in case of foreign body invasion and alert other cells involved in our immunity system

Eosinophils

These units kill cancer cells, parasites and aid against allergic reactions

Basophils

These units alert the body against disease-carrying pathogens in the body by producing histamine.

Conclusion

White blood cells in the blood system act as the immunity block of the body. These units are responsible for the health and consecutive benefits of our health by combating various germs, fungi, bacteria and viruses. WBCs are subdivided into various categories that have their specific functions and roles to respond against different situations. The Neutrophils are the first responders and the basophils act as the alarm system against an invasion of foreign bodies. Lymphocytes memorise the invasion of various pathogens that prevents their oncoming the second time. Eosinophils are responders against germs and allergic reactions and cancer cells. Monocytes are the ones that kill the dead blood cells in the blood system. These comprise only 1% of the entire blood system and these are produced at the sites of bone marrow.
