The immune system is our body 's defense system – it is vital to our body 's health and survival. We need the immune system to fight off bacteria, viruses, and other foreign, harmful substances - as well as our own cells that have become bad or even cancerous. There are several building blocks that make up the system as a whole, each just as important as the next, that work hand-in-hand. This includes the lymphatic system, biological molecules, antibodies, white blood cells, the tonsils, thymus, bone marrow, and the spleen. The tonsils and thymus both create antibodies, while bone marrow (among other things) creates white blood cells, which are crucial to fighting off infection. The lymphatic system carries waste as well as nutrients, and lymph fluid throughout the body in the blood stream. The lymph nodes act as a strainer or filter, so when the lymph fluid travels through, it traps virus 's, bacteria, and any other substance that 's foreign to your body. These things are then destroyed by lymphocytes, which are specialized white blood cells. The spleen, which also works as a filter, gets rid of aged or damaged platelets and blood cells, and also destroys bacteria and other harmful or foreign substances. When an autoimmune disease occurs, it is because the body has triggered an inflammatory defense response when there is nothing to protect the body from. Inflammation is what happens when white blood cells and immune proteins are fighting off infection. The immune system
spleen is a place for immune function, and it kills defective or aged red blood
As I was doing my research I came across the autoimmune part and totally lost. It’s a breakdown in the immune system. As we know every person produces their own cell types that fight off disease and infection. In order to fight off the bad bacteria our bodies must be able to recognize the bad known as antigens (often proteins) on the surface of the UN wanted invaders. Everyone’s immune system should be able to recognize the bad, and be able to fight it off. In an autoimmunity this is where the immune system is not able to recognize the invaders and fight them off.
A. An autoimmune disease is a disorder in which the body’s immune system attacks the body’s own cells and organs.
To understand autoimmune diseases, the general characteristic of autoimmunity must be addressed. Autoimmunity is defined, in short, as “ misdirected immune response”. A healthy person is equipped with the mechanisms necessary to defend the body from pathogens within the immune system. When autoimmunity is present in an individual, something within the immune system is
Autoimmune disease- any of a large group of diseases characterized by abnormal functioning of the immune system that causes your immune system to produce antibodies against your own tissues (the definition from wordnetweb.pronceton.edu).
The lymphatic system are a complex network of specialised cells and organs that defend the body against infection. Lymphatic organs include the bone marrow, spleen, thymus gland, lymph nodes, tonsils, adenoids, appendix and clumps of tissue in the small bowel. A function of the lymphatic system is to nurture and mature the B and T-lymphocytes (white blood cells vital to immune function). Cancerous changes can take place
Lymphocytes are a type of white blood cell, which are an important part of the immune system. Lymphocytes can defend the body against infection because they can distinguish the body’s own cells from foreign ones. Once they recognize foreign material in the body, they produce chemicals to destroy that material. Two types of lymphocyte are produced in the bone marrow before birth.
The lymphatic system plays an important part in the body’s defense against infection (Rockson, 2016).
The organs that make up the lymphatic and immune system are the tonsils, spleen, thymus gland, lymph nodes, and lymphatic vessels. White blood cells (leukocytes), red blood cells (erythrocytes), plasma, and platelets (thrombocytes) make up the blood. Lymphocytes are leukocytes (white blood cells) that help the body fight off diseases. Two types of lymphocytes are B cells and T cells. Lymphocytes recognize antigens, or foreign substances/matter, in the body. Lymphocytes are a classification of agranulocytes, or cells (-cytes) without (a-) granules (granul/o) in the cytoplasm. B cells are created from stem cells, which are located in the bone marrow. B cells respond to antigens by becoming plasma cells. These plasma cells then create antibodies. Memory B cells produce a stronger response with the next exposure to the antigen. B cells fight off infection and bacteria while T cells defend against viruses and cancer cells. A hormone created by the thymus gland called thymosin changes lymphocytes into T cells. The thymus gland is active when you are a child and slowly shrinks, as you get older. T cells bind to the antigens on the cells and directly attack them. T cells secrete lymphokines that increase T cell production and directly kill cells with antigens. There are three types of T cells: cytotoxic T cells, helper T cells, and memory T cells.
Rocks are the superior males and the pebbles are the weak females that have no power;, Rrocks can create mountains and hills, while pebbles can only be left with the dust and dirt, but one thing you did not know about pebbles is that they could skip in the river, rocks however are being eroded into pebbles and want change as the time pass. The pebbles are able to progress and be as strong and powerful as rocks as they skip along the river retaining a constant speed of strength to create a strong position for themselves. In the United States’ system of patriarchy, the rocks symbolize the “superior” men and the pebbles represent the women. Women are isolated from society and are shunned from power as the men grow with potential and authority.
The main organs that are involved in the immune system are the thymus, bone marrow, spleen, tonsils, and lymph nodes. The immune system works by having the white blood cells stored or produced in these organs. Since the white blood cells are all over the body, the immune system can constantly monitor the body for germs. There are also 2 types of white blood cells, the first is phagocytes which destroy
With autoimmune diseases, the underlying issue is similar. The body's immune system becomes unable to recognize healthy cells from diseased cells. Consequently, the immune’s own defense mechanism produces antibodies that attack the normal tissues and cells. Autoimmune diseases
What is nursing commonly known as? The public often recognizes nursing as women’s work: feminine. As a result of this stereotype, males are discouraged from pursuing a career as a nurse. Ever since the Nightingale era, male nurses have been looked down upon (Hsu, Chen, Yu, & Lou, 2010). There is a great amount of role strain, causing a high turnover rate (two males to one female), leading to healthcare disparity. In today’s era (and prior to), male nurses have historically been stereotyped and discriminated against in the field of nursing.
Often referred to as the Last Great Dynasty, The Qing Dynasty ruled China for over three centuries. The Qing were a proud dynasty and relied little upon foreign trade and influences to grow their economy. This was partly because The Qing were a self-sufficient society. Another reason for the denial of Western influences was due to The Qing’s great pride of their own culture. Any acceptance of Western influences would dilute the values and traditions of The Qing. That being said, The Qing did allow a trivial amount of foreign trade to take place in the Port of Canton. The refusal to allow Western influences, the lack of knowledge of the importance of foreign relations and the continued reliance of Confucian teachings all played a part in the demise of The Qing Dynasty. The modernization of China would not be possible without the rebellion of 1911.
The circulatory and immune systems are two very closely related systems. The circulatory is composed out of blood vessels, the heart, and blood. The immune system is made up of white blood cells and various lymph nodes. Basically, most of the immune system is found inside the blood of the circulatory system. The circulatory system provides the body with blood. It gives the kidneys of the digestive system something to filter and picks up nutrients from the small intestines. It also picks up air from the lungs of the respiratory system and provides the brain of the nervous system with blood, along with the rests of the body. Protection from wounds in the integumentary system is also provided by the circulatory system which has platelets that aid in blood clotting and forming scabs. The immune system protects all the other systems from disease and helps them from being attacked by viruses and bacteria. It also aids the ears of the nervous system with some very protective earwax. The circulatory system provides us with life fluid while the immune system protects that fluid and the rest of our body.
