Key Difference – T Helper vs T Cytotoxic Cells Lymphocytes are a type of white blood cells with a single round nucleus. They are important defense cells in vertebrates immune system. T cells or T lymphocytes are a subtype of lymphocytes. They are part of the adaptive immunity and are mainly involved in cell […]
Difference Between Primary and Secondary Immune Response
Key Difference – Primary vs Secondary Immune Response Humans and other animals live in an environment that is heavily populated by microorganisms. Some microbes are pathogenic and cause various types of infections. The immune system is the natural defense system of our body and the first line of defense designed to fight off against […]
Difference Between T Cells and B Cells
Key Difference – T Cells vs B Cells White blood cells are an integral part of the immune system. These cells fight against various types of foreign infectious particles including bacteria, viruses, and toxins that make people ill. The low number of white blood cells in the blood stream indicates a weakened immune system. […]
Difference Between Phagocytes and Lymphocytes
Key Difference – Phagocytes vs Lymphocytes The immune system acts against pathogens which enter the body. There are two types of immune cells involved in this action. They are phagocytes and lymphocytes. Phagocytes are a type of white blood cells which ingest foreign particles and destroy them. Lymphocytes are another type of white blood […]
Difference Between Specific and Nonspecific Immunity
Specific immunity is the immune response generated against a particular antigen using the production of antibodies while nonspecific immunity is the initial immune response against the vast array of foreign antigens using nonspecific antibodies and immune cells. This is the key difference between specific and nonspecific immunity. The immune response is the complex series of […]
Difference Between Humoral and Cell Mediated Immunity
The key difference between humoral and cell mediated immunity is that the humoral immunity (antibody-mediated immunity) involves antibodies while the cell mediated immunity does not involve antibodies. Immunity is the ability of an organism to defend against pathogens and toxins and to avoid infections and diseases. Therefore, the immune system is the tissue system that […]
Difference Between Innate and Adaptive Immunity
The key difference between innate and adaptive immunity is that innate immunity is a fast immune response that provides the first line of immunological defence against infections while adaptive immunity is a slow immune response mediated by the T and B lymphocytes. The major function of the immune system is to defend the host against […]
Difference Between T Lymphocytes and B Lymphocytes
The key difference between T lymphocytes and B lymphocytes is that the T lymphocytes originate in bone marrows and mature in the thymus while B lymphocytes originate and mature in bone marrows. The main two types of cells in blood are red blood cells (RBC) and white blood cells (WBC). RBC carries and transports oxygen […]
