Introduction
By examining blood smear by microscopy it can detect infections whether they are viral or bacterial. Blood smears are examined by looking at the white and red blood cells appearances.
The aim of the experiment is to compare a normal blood smear and its pathological features to those with an infection or abnormality by the use of microscopy looking at the cells involved with blood.
A normal blood smear would contain 3 to 4 white blood cells per field in microscopy. If there is an increase in the white blood cells per a field the body is in response to an infection. Also the shape of red blood cells would be biconcave disc and the centre pallor would be pale which occupy a third of the cell. Red blood cells have a small variation …show more content…
The function of platelets is to clot the blood by coagulation. They are formed in the blood marrow and with different diseases that affect the white blood cells and platelets they can have contributing illnesses such as bleeding.
There are 5 types of white blood cells; neutrophylls, lymphocytes, monocytes, esophylls and basophylls. They all have different functions and properties in the immune system.
The neutrophils are the most common and are a bacterial response. Therefore if the patient has a high amount of neutrophils you know that the patient is fighting bacteria. They have 3 to 5 lobes in their nucleus with granules within the cytoplasm. The way they kill bacteria is by engulfing the bacteria cell and dissolving the contents.
Lymphocytes attack a viral infection and are similar size to red blood cells. They have a large nucleus taking up 95% of the cell with very little cytoplasm in the …show more content…
These are responsible to fight and detect parasites.
Conclusion
The averages in the total blood count vary depending on the age or gender of a person also whether the woman is pregnant. http://www.docticare.co.uk/contenuti/img//Count_tabella.png http://www.docticare.co.uk/pagine/Complete-Blood-Count-or-Full-Blood-Count.aspx
Figure 1 shows that there is a different between gender on the amount of blood cells. Men have more blood and therefore need more RBC. Referring to figure two below it shows that men and women have a different value compared to children showing age is a variant. 4.5 to 6.2 million cells per microliter of blood for men 4.2 to 5.4 million cells per microliter for women 2.6 to 4.8 million cells per microliter for children
