Concept Map: 10 Immune System
Damani Polk Period 2 Anatomy
Major Functions or the Lymphatic & immune system
Immune System -to protect the host from environmental agents such as microbes or chemicals, thereby preserving the integrity of the body.
Lymphatic System -fluid balance, absorption of fatty acids in the stomach, and immune system regulation.
Location of Lymphatic Organs and their function
Thymus - Small organ that lies in the upper chest under the breast bone
Lymph Nodes -filter substances that travel through the lymphatic fluid, and they contain lymphocytes
Spleen - A fist-sized organ in the upper left side of your abdomen, next to your stomach and behind your left ribs
Lymphatic vessels - regulate fluid homeostasis, assist in immune surveillance, and transport dietary lipids
Bone Marrow - The soft, spongy tissue that is in the medullary cavities (centers) of bones
Purpose of First, second, and third line of defense
Second - Nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals
Third - Immune cells that target specific antigens. The immune cells that play a role in the third line of defense are B-cells and T-cells, both are white blood cells
Innate (first) -First line of defense against germs entering the body. It responds in the same way to all germs and foreign substances
Innate and adaptive immune defense
Adaptive - Attack and destroy foreign invaders and are able to prevent disease in the future by remembering what those substances look like and mounting a new immune response.
Innate Immune defense - It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body
Humoral response and cellular response
The humoral immune response is mediated by antibody molecules that are secreted by plasma cells
Cellular Response -the destruction of infected cells by cytotoxic T cells, or the destruction of intracellular pathogens by macrophages
Antigens and Antibodies
An antigen is a foreign substance that enters your body. This can include bacteria, viruses, fungi, allergens, venom and other various toxins.
An antibody is a protein produced by your immune system to attack and fight off these antigens
Artificial V.S Naturally acquired immunity
Naturally -someone is infected with the disease. Meaning they are at high risk for developing symptoms and side effects from the disease,
Artificial - Protection produced by intentional exposure of a person to antigens in a vaccine, so as to produce an active and lasting immune response.
Passive V.S Active immunity
Active immunity - Exposure to a disease organism triggers the immune system to produce antibodies to that disease
Passive Immunity -A type of immunity that occurs when a person is given antibodies rather than making them through his or her own immune system
Cells Involved in the Immune system
lymphocytes -Help you body fight cancer and foreign viruses and bacteria (antigens
Neutrophils - Boosts the response of other cells in the immune system
Monocytes -play a role in both the inflammatory and anti-inflammatory processes that take place during an immune response.
Disorders associated with the immune system
Mediterranean Fever -painful attacks early during childhood. Amyloidosis is the most fatal complication of FMF.
Crohn's Disease -swelling of the tissues in your digestive tract, which can lead to abdominal pain, severe diarrhea, fatigue, weight loss and malnutrition
Asthma - Causes repeated episodes of wheezing, breathlessness, chest tightness, and nighttime or early morning coughing
