Paste your essay in here..Erythrocytes are red blood cells in the body. They are typically described as biconcave discs without a nucleus. They contain this pigment referred to as hemoglobin. This pigment imparts the red color to blood, and transports oxygen and carbon dioxide to and from tissues. Erythrocytes bring oxygen from the lungs to the body and they bring back carbon dioxide for the lungs. You find these red blood cells in the blood as they are traveling. Males typically contain anywhere from 4.7 to 6.1 billion of these red blood cells. Females however, contain only 4.2 to 5.4 million .Leukocytes can be described as colorless cells that circulate inside the blood and body fluids. They also counteract any sort of foreign substances which are also known as diseases. This would describe the overall white blood cell. Most of these white blood cells are found in the lymph tissue and blood. They are produced in the bone marrow however. Their main role is to fight off infections and other diseases. The normal number of white blood cells someone carries is approximately 4,500 to 11,000 per microliter. These in a pack would be described as the bodies protectors. Neutrophils are phagocytic white blood cells that contain a neutrophil granules in the cytoplasm and a lobulated nucleus . You can typically find them circulating around our bodies in our blood streams. The human body on average contains approximately 1.5 to 8.0 (1,500 to 8,000/mm3). Neutrophils could be best described as someone you can trust and would would be a “first responder” buddy. Whenever they can tell an infection arriving, they are the first responders, fighting off the newly invading microbes .Eosinophils are another form of protectors. They help fight against bacteria and parasites that could be harmful to the body. It’s stabilized as a part of the immune system, and is depended on to keep combating the all foreign and infectious things. The body contains about 0.0-6.0% of eosinophil blood, and a eosinophil blood count of 30-350. When things such as allergies come about, eosinophil levels tend to rise. You can find leveled eosinophils in things such as asthma and diseases. Eosinophils also have a cytoplasm filled with large granules. Find eosinophils in tissue, intestines, skin, heart (only to name a few). Basophils are a type of white blood cell (also known as a leukocyte). It’s pointed out by its ability to be stained by simple dyes. Basophils tend to mediate hypersensitive reactions in the immune system. They represent less than three percent of the bodies white blood cells. The body should however contain 0 to 300 basophils per microliter of blood. Basophils are essential to keep blood from clotting . In order to do this, it uses heparin which basophils contain naturally. Heparin is a blood thinner, making it easy to prevent clotting since the blood won’t be so thick. Basophils also help during allergic reactions. They release histamine and typically look like your average white blood cell. You can find Basophils in the inflammatory response. They can also just be found in the skin which is where many of them reside. A monocyte is the largest cell amongst the white blood cells in the immune system. They are originally produced in the bone marrow however, are released into the tissues and blood of the body. Monocytes are responsible for fighting off diseases and infections. They have the ability to morph into macrophages right before encountering any germs. They actually consume any harmful bacteria, viruses and fungi. Then, the enzymes in the body of the monocytes kill and make the germs deteriorate into pieces. The percentage of this white blood cell is 0.2–1.0×10 9/l (2–10%) . B cells are a type of lymphocyte. They develop within the bone marrow. They also circulate in the blood searching for foreign antigens. ONce they encounter antigen, they morph into a clone of a plasma cell that secretes an antibody. Although they are produced in the bone marrow, they migrate over to the spleen and other lymphoid tissues. There, they mature and develop into B cells. They are apart of the immune system. B-cells make specific Y-shaped proteins in which are called antibodies. They (antibodies) stick to the antigens on the surface of different germs, and stop them in their attempts. This creates clumps that will alert your body that there are intruders. Your body will thus start to create different toxic substances to ward them. The Normal Number of B-cells s 8.4 percent +/- 2.1 for 30 ambulatory .
