The body's natural defense against infection primarily involves the immune system, which includes physical barriers like the skin and mucous membranes, as well as various immune cells such as white blood cells. These components work together to identify and eliminate pathogens like bacteria and viruses. Additionally, the body produces antibodies that specifically target and neutralize invaders, while inflammatory responses help to isolate and combat infections. Overall, this complex system provides a robust defense to maintain health and prevent disease.
The body's second line of defense, which includes inflammatory responses and phagocytic cells, comes into play when pathogens manage to breach the first line of defense (skin and mucous membranes). These responses help contain and eliminate the pathogens before they can cause harm.
Your skin is the first line of defense.
Deoxygenated blood, also referred to as oxygen-poor blood or venous blood. This blood is returning to the heart after delivering oxygen to the body's cells.
The body's main defense barrier against microorganisms is the immune system. This system includes physical barriers like the skin and mucous membranes, as well as specialized cells and proteins that identify and destroy pathogens to prevent infections. Additionally, the body has inflammatory responses that help to contain and eliminate invading microorganisms.

White blood cells, also known as leukocytes, are the cells that play a crucial role in the body's defense against invading microbes. They work by identifying and attacking foreign invaders such as bacteria, viruses, and other pathogens to help prevent infections.
This is your bodys natural defense to protect the eyes. It is a reflex.
