Basic Immunology Second year Laboratory medicine Introduction to immunology Immunology: Immunology is the science that studies the mechanisms by which human body defends itself from foreign substances present in the environment. It is divided into three major parts: 1. Basic immunology. 2. Diagnostic immunology. 3. Clinical immunology. Part I-Basic immunology History: Immunity is derived from the Latin word immunitas and was referred to the exemption or protection ...

This document offers a clear and concise summary of basic immunology, focusing on the essential elements of the immune system and its defense mechanisms. It covers innate and adaptive immunity, antigen recognition, lymphocyte development, immune memory, and the roles of key cells and molecules. Suitable for students in medicine, nursing, and health sciences as a foundational resource or exam preparation tool.

The immune system consists of specialized cells and organs that protect an organism from outside biological effects and from inside changes. If the immune system is functioning properly, it protects the body against microbial infections, destroying cancer cells and foreign substances. If the immune system weakens, it allows pathogens to grow and flourish. Organs of the immune system Central (primary) lymphoid organs These are the sites of maturation of the lymphocytes 1-Bone...

Basic Immunology Immunology • Can be defined as the study of a host’s reactions when foreign substances are introduced into the body. immunogen • A foreign substance that induces such an immune response is called an . • Immunology as a science has its roots in the study of immunity, the condition of being resistant to infection. Immunity • All those physiological mechanisms that endow the animal with the capacity to recognize materials as foreign to itself and to ...

BasicImmunology INTRODUCTION ◼Immunology is the study of host defencemechanisms. ◼Immunity is the ability of the host to protect itself against foreignorganisms. ◼The immune system comprises the tissues, cells & molecules which mount the immuneresponse. Coagulation
