So, I'm back in school for those that hadn't read that yet! Hold on to your hats! LOL! It's been a while since I've done this.
But, what I wanted to share is a really good descript
ion of the different parts of our immune system and what they do. For most of us, this information was not presented, we didn't pay enough attention, or, it's just been too long! LOL!
SOME COMPONENTS OF THE IMMUNE SYSTEM
The immune system is comprised of a team of organs and defense cells—the doorways through which foreign substances must pass and survive in order to continue toward their path of infection.
The first boundary to infection is the external immune response: the healthy anti-bacterial terrain of our skin, tears, mucus, saliva and stomach acid. Normal skin is tough and generally impermeable to bacteria and viruses, and it contains special cells—Langerhans cells—that are early warning signs to the immune system.
Germs that pass through the nasal passage and lungs are trapped in mucus and swallowed. Tears capture and expel germs before they can continue permeating the body through the eyes. The body’s external defenses keep most germs in circulation at bay.
The Immune System- If physical and chemical barriers fail—or the terrain is suboptimal—then the internal immune response steps up to the plate. The internal immune response identifies the pathogen and communicates with other cells to organize and coordinate the immune-response to eliminate or suppress the germs. If the pathogen cannot be completely destroyed, the body opts to contain and suppress it to keep it from spreading.
The immune system is integrated into the tissues of other bodily organs. Let’s take a look at the
locations of the lymphoid tissues of the body and the immune cells so we can better understand the immune system’s pathway.
Lymph system: The lymphatic system is a network that passively carries lymph fluid throughout the body using the everyday movement of the body’s skeletal and smooth muscles. Lymph fluid originates from interstitial fluid which is collected in lymph capillaries. The system removes waste, dead blood cells, toxins, and other pathogens. The lymph moves upward through the body in one-way vessels toward the neck, passing through lymph nodes that contain tissue filters and high amounts of lymph cells. These are the glands that swell during bacterial infection. The lymph enacts clean up and defense—and contains leukocytes, which are explained below.
Spleen: Acts as a large lymph node and filters the blood. The spleen removes and cleans antibody-coated bacteria that have just been filtered through the lymph system. It contains half of the body’s monocytes, a type of white blood cell that gobbles up pathogens and moves quickly to the site of inflammation.
location of the production of red blood cells and white blood cells, it is a key component of the lymph system—the birthplace of the leukocytes.
White blood cells (WBCs), or leukocytes, are unlike other cells in the body in that they can act like independent organisms, able to chase and engulf other cells and bacteria. They do not replicate themselves, but are produced in the bone marrow. Leukocytes are divided into cells with specific names depending on their specific job. Let’s explore a few of the basic categories of work these WBC’s accomplish in their lifetime.
Granulocytes: Immune responders that lie in the tissues and respond to chemicals from inflammation, parasites, allergies and other pathogens. There are three types of granulocytes: Neutrophils, Basophils, Eosinophils.
Granulocytes are all phagocytes – they ingest and dispose of pathogens and dead or dying cellular debris, and in some cases respond chemically to call on more immune responders at the site of the defense.
Lymphocytes: Two types of lymphocytes respond to pathogens in the body. Upon their activation, T and B-cells leave a lasting memory of the pathogens in memory cells.
B-cells produce large quantities of antibodies that then neutralize foreign objects like bacteria and viruses. B-cells respond to bacteria, exposed viruses, antigens, antibody mediated inactivation/ tagging.
T-cells either direct the immune response while other T-cells induce the death of pathogen-infected cells. T-cells respond to virus-infected cells, fungi, some bacteria, self, transplants, and cell-to cell interactions
The thymus gland lives between the breastbone and the heart and is responsible for T-cell production. In utero, an embryo’s WBCs identify self-reactive immune T-cells and eliminate them, while multiplying self-friendly T-cells. As an infant, we are dependent upon our thymus for properly functioning immunity. In adults, new T-cell production in the thymus is low, but circulating T-cells in the blood do not decrease. It is thought that mature T-cells either have long life spans or can reproduce themselves.
Antibodies: a large protein used by B-cells to identify and neutralize bacteria and viruses.
