The Immune System
System that protects the body from harmful substances, such as disease-causing bacteria, viruses and microorganisms
What is the immune system?
•Composed of the lymph, lymph vessels, lymph nodes, spleen and thymus gland
•Produces and moves lymph fluid from the body’s tissues to the circulatory system
•Removes excess fluids and wastes products from the tissues
•Transports fats and vitamins from the GI tract to the circulatory system
•Also helps the immune system to fight infection
What is the lymphatic system?
Antibody response gets faster
What is not a normal change in aging?
This is a shot that introduces a weak or dead antigen to help your body learn to fight a disease.
What is a vaccine?
This viral disease, caused by SARS-CoV-2, spreads through respiratory droplets and can cause fever, cough, and difficulty breathing.
What is COVID-19?
•Present at birth and protects the body from disease in general
•First line of defense from invasion
•Produces white blood cells which fight against the pathogen
What is nonspecific immunity?
is a clear yellowish fluid that moves in the lymph system from the tiny capillaries in the circulatory system, carries disease-fighting cells called lymphocytes
What is lymph?
Response to vaccines decrease
What is a normal change in aging?
These proteins stick to antigens to help destroy them or mark them for other immune cells to attack.
What are antibodies?
This disease, spread by mosquito bites, can cause fever, chills, and sweating, and is common in tropical areas.
What is Maleria?
•Immunity that is acquired by the body
•Can be either active or passive
What is specific immunity?
an example of this is the tonsils
What are the lymph nodes?
T-cells increase in number
What is not a normal part of aging?
These molecules, often proteins or polysaccharides on the surface of pathogens, trigger an immune response by being recognized as foreign.
What are antigens?
This tiny organism, invisible without a microscope, causes diseases like strep throat or tuberculosis.
What is a bacteria?
body manufactures antibodies as a responds to an antigen from a pathogen. The body then “remembers” the pathogen each time it is exposed in the future. This immunity can be developed from a vaccine.
What is active immunity?
Located in the abdomen, this organ filters blood and helps remove old or damaged red blood cells while also storing immune cells
What is the spleen?
these are items elderly patients may require for urinary elimination or nutrition and greatly increase the risk of infection
What are lines, tubes and drains?
this is an organ that produces T-cells and shrinks as a person ages
What is the thymus?
this medication was accidentally discovered in a lab when a scientist was studying mold, and is credited for saving millions of lives. It is an antibiotic
What is Penicillin?
When a person is given the antibodies to defend against an antigen. Antibodies can be passed from mothers to babies.
What is passive immunity?
lymph carries the disease-fighting cells known as
What are lymphocytes?
often times, elderly patients spend more time in this place which places them at a higher risk for infection
What are hospitals and facilities?
this type of immune cell is a key player in an allergic reaction
What is an eosinophil?
This highly contagious viral disease causes fever, cough, and a distinctive red rash, and "factory resets" the immune system, erasing it of its specific immunity
What is Measles?
