White Blood Cells

White blood cells are part of the immune system and help defend the body from antigens.

a. Lymphocytes are a type of white blood cell, which are an important part of the immune system. Lymphocytes can defend the body

 The blood cell is made in the bone marrow of a bone and then enters a vein and goes toward to superior vena cava. The blood cell joins millions of other blood cells as well as white blood cells and platelets inside of plasma.

To identify red blood cells, basophils, eosinophils, monocytes, lymphocytes, neutrophils, sickle cell anemia and leukemia.

In this paper I will answer some questions about blood and related issues. Some of the questions I will answer are: what is the significance of a lower than normal haematocrit? what is erythropoiesis?why would the level of leukocytes be higher in an individual who has been infected with a parasitic disease. In regions where malaria is endemic, some people build up immune resistance to the malaria pathogen. Which WBCs are responsible for the immune response against pathogens? How do they function?

The organism is usually found in the cell in a particular category of white blood cells with

Finally, white blood cells are crucial to the immune system to serve as a defense against invaders such as bacteria, viruses and parasites with the ability to recognize between “friend or

Plasma cells are a type of white blood cell formed from B cells produced in a person’s bone marrow. B cells mainly stay within the bone marrow and are responsible for a specific defense mechanism that involves the production of antibodies by plasma cells. These antibodies are able to move

inside the blood marrow, and later stored in the lymphatic system (Wolofsky 2012). However, they don’t have hemoglobin and lack of color like RBC. Their life span is much shorter than RBC, each WBC last from one to three days. Therefore, the bone marrow must constantly produce them to restore the supply. Another difference between RBC and WBC is that the WBC is much greater size than RBC. There are five different types of WBC and each contain an important functions of fighting disease. First, there is neutrophils which make up the greatest percentage of WBC, ranged from 50 to 70 percent of total WBC. Neutrophils protected the body from bacteria and fungi infection. They are very active and are considered to be the first invader to diseases

Background: Innate immunity is the first line defense against invading microbes pathogens. Human blood is full of cells that express immune system such as Neutrophils. The most important operation that Neutrophils do in this lab is phagocytosis. Phagocytosis is normal reaction white blood cells doing when human body is under attack from bacterial pathogens.

The production of white blood cells, red blood cells and platelets happens in bone marrow. The bone marrow produces extra white blood cells when an infection occurs. According to Gordon-Smith (2013), the main function of white blood cells is to respond to infection in the body by killing the pathogen. However, traumatic bone marrow injury may cause the abnormality of blood production. Snyder (2012) states, extreme exposure to the toxin, such as benzene can harm the bones and affect the production of blood. The condition calls Leukaemia or blood cancer, which is the development of excessive amount of abnormal white blood cells. As the result, the bone marrow is not able to produce mature white blood cells. According to Cancer Council Victoria

Mast cell- produce histamine, a chemical that dilated small blood vessel during inflammation in addition to the anticoagulant heparin (477)

The skin is the body's first line of defense it acts as a physical barrier and when there are breaks in the barrier, such as cuts the body reacts to produce blood clots and a mesh work of fibrous tissue. The opening is blocked, which prevents germs or pathogens that can cause disease, from entering the body. One important defensive mechanism involving blood is clotting. These pathogens may breach this first line of defense and enter the body. Some white blood cells called phagocytes, move out of the blood and to the infected areas. They surround the invading micro-organisms, killing and removing them from the body before they can cause disease. If more dangerous, specific pathogens enter, then an immune response is activated. Another kind of
