these mutated cancer cells crowd out healthy cells and cause Hodgkin’s lymphoma. Hodgkin’s lymphoma can further be broken down into four subtypes: Nodular sclerosis Hodgkin ’s lymphoma‚ Mixed cellularity Hodgkin ’s lymphoma‚ Lymphocyte-depleted Hodgkin ’s lymphoma‚ and Lymphocyte-rich classical Hodgkin ’s lymphoma. Non-Hodgkin lymphomas are a second type of cancer that originates in the lymphatic system. This type of cancer is more common than Hodgkin’s lymphoma. “Non-Hodgkin lymphomas begin when

It is believed that the disease begins when an lymphocyte becomes abnormal‚ the abnormal cell then begins to divide to make more and more copies of the “bad” cell. The abnormal cells begin to build up and the white blood cells collect around the abnormal cells. This causes the first sign of Hodgkin Lymphoma

The white blood cells that are most commonly involved in this process are neutrophils‚ monocytes and lymphocytes. Neutrophils are the most common of the WBC’s and are the first ones to respond to the site of an injury. They are the first defense against any bacteria trying to enter

Monocytes and lymphocytes are different types of basophils. Monocytes are the largest type of blood cells. Lymphocytes are little larger red blood cells‚ with large‚ round nuclei. 7.

Introduction Acute lymphoblastic leukemia (ALL) is a fast-growing cancer of the white blood cells. Lymphocytes are a type of white blood cell that the body uses to fight infections. In ALL‚ the bone marrow makes lots of unformed cells called blasts that normally would develop into lymphocytes. However‚ the blasts are abnormal. They do not develop and cannot fight infections. The number of abnormal cells (or leukemia cells) grows quickly. They crowd out the normal red blood cells‚ white blood cells

Lesson 7.01 Nervous and Endocrine Systems Neurons: A nerve cell‚ the fundamental unit of the nervous system that conducts electrical signals through the body. Impulses: Electrical signals conducted through the body’s nervous system by neuron cells. Electrical signals called impulses are carried throughout the nervous system by specialized cells called neurons. Neurons cells can vary in shape‚ size‚ and specialized function‚ but they all share some common features. The cell body is the largest

Wars have been occurring since the dawn of time. Wars are states of armed conflict between societies that bring death‚ destruction‚ merciless slaughter and butchery‚ and starvation‚ poverty‚ ruin and disease in its wake. Apart from casualties during wars‚ a significant cause of death during most wars is disease. A clear example of this is the Mexican War of Independence. It was much more difficult to prevent deaths from tuberculosis during this war because of lack of knowledge of the disease‚ a

visualization of these mechanism and their processes. Killer T-cells combine with antigens on the surface of any invading cell and release a powerful group of chemicals called lymphokines. Some lymphokines kill the pathogens directly‚ others stimulate lymphocytes to become active and help increase the inflammation so that there are more macrophages. Helper T-cells co-operate with B-cells in the antibody production. They also activate macrophages and promote inflammation. Memory cells remain even after the
