There are three main types of lymphocytes: B cells, T cells, and natural killer cells. Two of these types of lymphocytes are critical for specific immune responses. They are B lymphocytes (B cells) and T lymphocytes (T cells). B cells B cellsdevelop from bone marrowstem cellsin adults. ...
Lymphatic vessels transport lymph to lymph nodes. These structures filter lymph of pathogens, such as bacteria and viruses. Lymph nodes also filter cellular waste, dead cells, and cancerous cells. Lymph nodes house immune cells called lymphocytes. These cells are necessary for the development of hu...

B lymphocytes become activated when they bind to their specific antigens. Then they divide into two different types of cells, known as memory cells and plasma cells. One important role of lymphocytes is the production of antibodies, and plasma cells are responsible for this. They are able to ...
These lymphocytes are one of many types of leukocyte, or white blood cell. The immune system also includes the spleen, the bone marrow and a gland called the thymus. The immune system can learn to recognize antigens— proteins on the surface of bacteria, fungi and viruses — and alert the...
Types of lymphoma More than 70 kinds of lymphomas have been described, and they are grouped in two main types—Hodgkin and non-Hodgkin lymphoma. Hodgkin lymphoma In most cases of Hodgkin lymphoma (HL), the neoplastic cells are derived from mature B-cells. It preferentially develops in young ...
There are three types of lymphocytes: natural killer cells (NK), B-lymphocytes (B), and T-lymphocytes (T). NK cells destroy cells infected by viruses and cancerous cells. Necessary for humoral immunity, B cells are manufactured within the bone marrow, differentiating as plasma cells responsible...
What are the six functions of hepatocytes? Hepatocytes: The hepatocytes are the epithelial cells are present in the liver of animals and humans. These are rapidly differentiating cells. These are responsible for the synthesis of important substances in the body and in metabolic functions. ...
Which type of cell, if any, does not have a plasma membrane? What are myoepithelial cells? What kind of cells are lymphocytes? What are immature germ cells? What are epidermal dendritic cells? What are granules in cells? What are the three kinds of cell membranes? What is the best for...
