Types of Immune System (With Diagram)| Microbiology

There are two types of immune systems: 1. The Humoral Immune System 2. The Cell Mediated Immune System. 1. The Humoral Immune System: The humoral immune system involves the antibodies that get dissolved in extracellular fluid such as blood plasma, lymph and mucus secretion. These were formally known as humors. The humoral immunity is conferred through B-cells that develop from [...]

Organs in Immune System of Humans | Immunology

The following points highlight the two main types of organs present in immune system of humans. The types are: 1. Primary Lymphoid Organs 2. Secondary Lymphoid Organs. Type # 1. Primary Lymphoid Organs: Primary lymphoid organs (PLO) are the major sites of lymphocyte development i.e. lympho­poiesis. Lymphocytes differentiate from lymphoid stem cells, proliferate and mature into functional cells called immuno-competent [...]

Steps Involved in Cellular Immune Response | Immunology

In this article we will discuss about the steps involved in cellular immune response. Host defenses that are mediated by antigen specific T-cells and various non-specific cells of the immune system is called cell mediated immune responses. Cellular immune responses have an activa­tion phase and an effector phase. These phases occur as follows (Fig. 10.2): 1. A viral protein made [...]
