Body defense system

What is the major defense system of the human body? Small vessels become permeable = swelling 3. The skin, nails and hair form the integumentary system , which stops dirt and pathogens from entering the body. There are two systems that specialize in self-defense : the lymphatic system and the immune system.

Microbes are the tiniest living things on Earth. Until these proteins are activated by infection, they circulate in the blood in an inactive state.

The body has two lines of natural defense to protect against infection. The first are physical barriers, such as the skin, body secretions and mucous membranes. The second line of defense is the immune system.

Protects the body against foreign body invasion. The innate immune system is a non-specific response that includes deterrents like the skin, enzymes in saliva, and inflammatory reactions by immune cells. Our evolutionary body armor is impervious to water and does not degrade with moisture or time and therefore will outlast and outperform anything on the market.

Lymphocytes include B cells and T cells. These are your specialized task force members.

Phagocytes can be free-roaming, neutrophils or monocytes (other types of immune cells). The immune system is your body’s natural defense system. They are the clean-up crew.

It’s an intricate network of cells, tissues, and organs that band together to defend your body against invaders. Those invaders can include bacteria, viruses, parasites, even a fungus, all with the potential to make us sick. It filters out organisms that cause disease, produces white blood cells, and generates disease-fighting antibodies.

The lymphatic system is also a defense system for the body. It also distributes fluids and nutrients in the body and drains excess fluids and protein so that tissues do not swell. If bacteria or viruses do gain entry, the body is furnished with a composite, multifaceted internal defense system — the Immune system — that provides around the clock protection against invasion by foreign agents.

The skin acts as a barrier and prevents most pathogens from entering the body. Secondly, both the innate and the adaptive immune system also need several soluble substances found in blood and other body fluids. What different systems make up a person?

The nonspecific defense system is made up of inflammation, fevers, etc.

Complement proteins also work along with the immune response by tagging to the outer surface of invaders for attack by phagocytes and complements the actions of the immune system. Interferons and Natural Killer Cells – Defense Against Viruses: Two components of the immune system fight only viruses, interferons and natural killer cells. The cells involved are white blood cells (leukocytes), which seek out and destroy disease-causing organisms or substances. There are different types of leukocytes. This is the immune system.

The human body is very resilient with both internal and external defenses that help overcome several foreign invaders. Topics include foreign invaders and the different parts of the defense systems. Individual Susceptibilities. Physical and Chemical Barriers (Innate Immunity) 2. The Immune System has Lines of Defense Against Foreign Pathogens: 1. Specific Resistance (Acquired Immunity) Physical and Chemical Barriers (Innate Immunity) Physical and chemical barriers form the first line of defense when the body is invaded.

Nonspecific Resistance (Innate Immunity) 3. When the immune system is weakened by the virus HIV, it is mostly a specific group of T cells that is reduced in number, the so-called T helper cells. Then the body is especially susceptible to infections by what are usually harmless pathogens.
