Module 7 Flashcards
What is the function of the immune system?
The functions of the immune system: 1) is to act as a defence mechanism to protect our bodies from disease-causing microorganisms that invade our bodies 2) to destroy and remove our own cells that are diseased or malignant, no longer functioning normally 3) to identify “non-self” cells and tissues, and also remove them from the body (as in the case of tissue or organ transplants)
What is nonspecific immunity? List four specific examples.
It is the system of structures and mechanisms in the body that intercept and attack any irritant or abnormal substance that threatens the internal environment. E.g. skin, mucous membranes, tears, and cilia.
What is an inflammatory response? What are characteristics signs of inflammation?
It is a cascade of events that happens in the immune system in response to injury or invasion by microorganisms or foreign proteins. Characteristics signs of inflammation or swelling, redness, heat, and pain.
What is specific immunity?
‘Specific immunity’ is the term for the highly specialized response of the immune system to invading microbes or foreign proteins.
What is”inherited immunity”?
Inherited immunity is the immunity that is inborn from birth, such as immunity to distemper (humans are unaffected by this canine virus because of inherited immunity to it).
What is “acquired immunity”?
Acquired immunity is immunity that is developed from exposure to invading microorganisms, together with a proper immune response (can be either natural or artificial exposure i.e. vaccinations)
What is “passive immunity”?
Passive immunity is immunity to disease that has developed in another individual and is transferred to an individual who is not previously immune e.g. anti-bodies in mother’s milk provides passive immunity for her infant.
Explain the difference between ‘Natural Immunity’ and ‘Artificial Immunity’?
‘Natural Immunity’ occurs when the body is exposed randomly and naturally to a foreign agent. ‘Artificial Immunity’ results from deliberate, artificial exposure i.e. immunization
What are antibodies?
Antibodies, a.k.a. immunoglobulins,are Y-shaped proteins which help to identify and remove foreign agents (antigens) from the body. Specific antibodies are produced to respond to specific antigens. The Y-like structure is such that it can bind to multiple antigens at one time, forming antibody-antigen clusters that are easily eliminated by killer cells. Antibodies also “tag” foreign proteins by attaching to them, which then makes them more easily detectible by phagocytes that are on a mission to ‘consume’ them.
What is complement fixation?
Complement fixation is a process whereby the binding of an antibody to an antigen exposes secondary binding sites on the antibody itself, called complement-binding sites. At the same time, specific proteins in the blood called “complement” proteins are activated by the antibody-antigen binding, and secondarily bind to the newly exposed complement-binding sites. This antibody-antigen-complement complex has a special ability to “puncture” the foreign (or malignant) cell membrane, causing sodium influx into the cell, and subsequent lysis or cell death, due to the resultant movement of water into the cell by osmosis.
What are phagocytes?
Phagocytes are white blood cells derived from bone marrow that ingest and eliminate foreign agents. Neutrophils and monocytes are two different kinds of phagocytic cells. Neutrophils are short-lived, but monocytes migrate into tissues where they are changed by chemical influences into giant phagocytic cells called macrophages. Macrophages secrete substances that attract other white blood cells to the infection site. Some macrophage cells are permanent in tissues, such as Kupffer cells in the liver and dust cells in the lungs.
What are lymphocytes?
Lymphocytes are The most prolific cells of the immune system, originating from the bone marrow, they are ultimately responsible for antibody production. They “patrol” the body continually, searching out any possible “enemies”. Dense populations are found in lymph nodes and other lymphatic tissue as well, such as the thymus gland and spleen and liver.
What is the function of B cells?
B cells are a type of lymphocyte that are responsible for producing massive amounts of antibodies. Initially formed in the bone marrow, B cells migrate to and inhabit lymph nodes where they are on constant monitoring duty. Immature B cells already have preset antibody proteins in them and are “primed” to produce those antibody proteins when they encounter their “matching” antigens. When they are “activated”, B cells differentiate into two different kinds of cells – plasma cells and memory cells. Plasma cells produce copious amounts of antibodies – 2000 per second – during their short lifespan. Memory cells, on the other hand, are “potentiated” and ready to produce the same antibody proteins, but they remain in reserve in the lymph nodes until a point in the future when the same triggering antigen is encountered, and the memory cells jump into action and immediately begin producing copious amount of the required antibodies. Hence why it is called “acquired immunity”.
What is the function of T cells?
T cells are another type of lymphocyte that originates in the bone marrow, but goes on to mature in the thymus. As we mature, T cells leave the thymus and migrate chiefly into blood circulation and also to the lymph nodes where they reside permanently. T cells, like B cells, are “primed” with a membrane protein called a T-cell receptor that has potential specificity for a particular antigen. When it encounters its “counterpart antigen”, it becomes “activated” and can either kill its target cell directly by producing chemicals (in the role of a Killer or NK T-cell) or by secreting messenger chemicals that “call in” macrophages to destroy the enemy cells and also stimulate B cells to produce antibodies (in the role of a Helper T-cell)
What is an allergy?
An allergy is a hypersensitivity of the immune system to relatively harmless environmental antigens (a.k.a. allergens). Long-term exposure to an offending allergen stimulates the production of antibodies to that foreign protein. Thus sensitized, whenever exposed to that particular allergen, the antibody arsenal creates antibody-allergen complexes, which in turn trigger enmasse production of histamines and kinines (chemical messengers), resulting in the symptoms of allergies – itching, swelling, inflammation, mucus production, hives, and breathing difficulties.
What are three common groups or types of allergies?
1) food 2) chemicals 3) inhaled allergens

What is autoimmunity?
Autoimmunity is an inappropriate and excessive response to one’s own tissues (ie. self- antigens). Disorders that result from autoimmune responses are called autoimmune diseases. Some examples of autoimmune diseases are: Crohn’s, Graves’ disease, Lupus, MS, rheumatoid arthritis, and celiac disease.
What is Crohn’s disease? What are some aromatherapy considerations and modes of use for this disease?
Crohn’s disease is a form of ulcerative colitis that causes ongoing chronic inflammation of the gastrointestinal tract. Crohn’s may occur in any parts along the G.I. tract – it can affect the large intestine, the small intestine, the rectum, or the mouth. The inflammation causes intestinal walls to thicken. Symptoms include:
- crampy abdominal pain
- fever
- fatigue
- loss of appetite
- pain with passing stool (tenesmus)
- persistent, watery diarrhea
- unintentional weight loss
- constipation
- eye inflammation
- fistulas (usually around the rectal area, may cause draining of pus, mucus or stools)
- joint pain
- liver inflammation
- mouth ulcers
- rectal bleeding and bloody stools
- skin lumps or sores (ulcers)
- swollen gums
- Aromatherapy considerations: treatment of the individual symptoms includes but is not limited to essential oils are analgesic, anti-inflammatory, antispasmodic, carminative, and calming.*
- Modes of use:*
- light massage
- bath
- compress
- diffusion
What is Graves’ disease? What are some aromatherapy considerations and modes of use for this disease?
- Graves’ disease is an autoimmune disorder that leads to overactivity of the thyroid gland (hyperthyroidism). The thyroid gland is an important organ of the endocrine system, which is located just below the larynx in the neck. This gland secretes the hormone thyroxin (T4) and triiodothyronine (T3) which control body metabolism. This is critical for regulating mood, weight, mental and physical energy levels. Graves’ disease is the most common cause of hyperthyroidism. It is caused by an abnormal immune response that causes the thyroid gland to produce too much thyroid hormones. It is most common in women over the age of 20 but can occur at any age and in both sexes.*
- The main symptoms of Graves’ disease are:*
- anxiety/nervousness
- breast enlargement in men
- difficulty concentrating
- double vision
- eyeballs that stick out (exophthalmos)
- eye irritation and tearing
- fatigue
- frequent bowel movements
- goiter
- heat intolerance
- increased appetite
- increased sweating
- insomnia/restlessness and difficulty sleeping
- menstrual irregularities in women
- muscle weakness
- rapid or irregular heart beat (palpitations or arrhythmia)
- shortness of breath with exertion
- tremors
- weight loss (rarely, weight gain)
- Aromatherapy considerations: treatment of individual symptom including but not limited to stress, insomnia, fatigue, depression, concentration, inflammation, emmenagogue, and slowing the autonomic nervous system.*
- Modes of use:*
- light massage
- bath
-
compress
- diffusion
What is Lupus? What are some aromatherapy considerations and modes of use for this disease?
- Also known as systemic lupus erythematosus (SLE) is a chronic inflammatory disease that affects many tissues in the body, joints, blood vessels, organs, nervous system and skin. The name lupus erythematosus refers to the red rash that often develops on the face of those affected. The “systemic” part but the name refers to the fact that the disease affects many systems throughout the body, as a result of production of antibodies against many different self-antigens.*
- Aromatherapy Considerations: rather than treating the disease as a whole, essential oils should be chosen that will help with specific symptoms of the autoimmune disease. For instance, essential oils that are anti-inflammatory, analgesic, soothing to the skin and circulatory stimulants should be used.*
- Modes of Use:*
- Light massge
- Foot baths
- baths
- compress
- diffusion
What is multiple sclerosis? What are some aromatherapy considerations and modes of use for this disease?
- MS is an autoimmune disease that affects the brain and spinal cord (central nervous system). It affects more women than men it is most commonly diagnosed between the ages of 20 and 40. MS is caused by damage to the myelin sheath, the protective covering that insulates and surrounds neurons. When this nerve covering is damaged, nerve impulses “short out” and are slowed down or stopped. The nerve damage is caused by inflammation, accompanied by the triggering of immune cells which attack the nervous system. Repeated episodes of inflammation can occur along any area of the brain, optic nerve, or spinal cord. Researchers are not sure what triggers the inflammation but the most common theories point to a virus or genetic defects, or a combination of both. Geographic studies indicate there may be environmental factors. Symptoms vary, because the location and severity of each attack may be different. Episodes can last for days, weeks or months. Fever, hot baths, sun exposure, and stress can trigger or worsen attacks.*
- Muscle symptoms:*
- Loss of balance
- muscle spasms
- numbness or abnormal sensations in any area
- problems moving arms or legs
- problems walking
- problems with coordination and making small movements
- tremor in one or more arm or legs
- weakness in one or more limbs
Bowel and bladder symptoms:
- Constipation and stool leakage
- difficulty beginning to urinate
- frequent need to urinate
- strong urge to urinate
- urine leakage (incontinence)
Eye symptoms:
- Double vision
- Eye discomfort
- Uncontrollable rapid eye movements
- vision loss (usually affects one eye at a time)
Numbness, tingling or pain:
- Facial pain
- painful muscles spasms
- tingling, crawling, or burning sensation in the arms and legs
Other brain and nerve symptoms:
- decreased attention span, poor judgment, and memory loss
- difficulty reasoning and solving problems
- depression or feelings of sadness
- dizziness and balance problems
- hearing loss
sexual symptoms:
- problems with erections
- problems with vaginal lubrication
Speech and swallowing symptoms:
- Slurred or difficult-to-understand speech
- Trouble chewing and swallowing
- Fatigue is a common and bothersome symptom as MS progresses. It is often worse in the late afternoon.*
- Aromatherapy considerations: Shirley Price writes about three patients suffering from MS. Essential oils were chosen as that would help with persistent pain, balance the immune system, address muscle fatigue, and stimulate circulation and memory. Essential oil of Rosemary officinalis, sandalwood, lemongrass, and geranium were used. Because there are so many symptoms related to MS, the list of recommended essential oils would be too lengthy to list here. Aromatherapists should choose several of the most debilitating symptoms and their recommended essential oils. Research has shown that massage is very helpful in MS and so the optimal treatment would include the specific essential oil applied by massage.*
