Short Essay On Immune System

The immune system is made up of many interdependent cell categories such as cells, proteins, tissues, and organs that work together to protect the body. Several of these cell categories partake in a particular function. “The cells of the immune system can engulf bacteria, kill parasites or tumor cells, or kill viral-infected cells (The Immune System and Primary Immunodeficiency, n.d.)”. The immune system is a great teamwork among cells and proteins that work together to deliver defend against infection. The cells and proteins are not just one organ like the liver and the heart. The immune system is spread throughout the body to deliver a quick reaction to infection in the body. Cells are in our bloodstream and that’s how they travel throughout the body. The immune system is made of many different organs to protect the body.
One of the vital cells that are involved are white blood cells, which are best known as leukocytes. Leukocytes have
Antibodies, are better known as immunoglobulins, they are a Y-shaped proteins that are formed by the immune system to stop invaders from hurting the body (What Are Antibodies? - Definition, Function & Types, n.d.). The adaptive immune system is efficient at birth, but because it is so new to everything it has not gained the knowledge or skills required for ideal memory responses. Even though this development of memory happens during life, the greatest gain in immunologic experience is between birth and the first three years of life. Each transmittable introduction leads to training of the cells so that a response to a second exposure to the same infection (The Immune System and Primary Immunodeficiency, n.d.). In the first years of a child’s life the catch many infection and their body create antibodies to fight off the
