Lymphatic system cycles through?
Lymphatic capillaries, Lymph vessels, lymph nodes,
A thin plasma-like liquid formed from interstitial or extracellular fluid that bathes the tissues of the body
Lymph
After the lymphatic system cycles the fluid returns through the main circulatory system via the?
Thoracic duct
What occurs if the lymphatic system isn’t working correctly and fluid backs up?
Edema
Lymphatic vessels only carry fluid ________ from the tissues
Away
Lymph vessels pass through at least _____________ ________ before entering the blood stream
One lymph node
A type of white blood cell that helps fight infection and provide immunity
Lymphocytes
Tissue with no clear boundary that blends with surrounding tissues and contains lymphocytes and other cells
Diffuse lymphatic tissue
The spreading of a disease from one part of the body to another, especially with many forms of cancer
Metastasize
A triangular-shaped gland located below the sternum in the superior mediastinum
Thymus
Spleen is located in the left upper quadrant and consists of two types of lymph tissue
The red pulp and white pulp
An immune response that is predictable each time the body is exposed to a particular challenge
Nonspecific immunity
The immune response to a given substance that is faster and stronger after each subsequent exposure
Specific immunity
What is the most important component of the immune system?
Leukocytes
Certain types of Leukocytes ingest and destroy foreign matter by the process of?
Phagocytosis
Larger cells ______________ are able to leave the bloodstream and enter diseased tissue once invader bacteria is destroyed
Macrophages
Immune globin or IgG comprises ____ to ___ of total serum antibody and is responsible for numerous actions, including Rh reactions
80% to 85%
We are born with ________ immunity
Natural
Natural immunity is
Genetic or natural passive immunity results when antibodies produced by the mother cross the placental barrier to provide protection against fetal infections
The immunity that develops in ones lifetime and is a reaction in the body occurring as a result of natural exposure to invaders or from a deliberate exposure to an antigen
Acquired immunity
Infectious disease that is spread through droplets from coughing and sneezing
Tuberculosis (TB)
Where is TB prevalent?
Nursing homes, homeless shelters, hospitals, prisons, migrant farm camps, and among IV drug users and HIV-positive individuals
What is the most frequent infectious disease found in prehospital care
Pneumonia and hepatitis
Several infectious agents are
Bacteria, viruses, fungi, protozoans, nematodes, and prions
Cause most serious human infections, including TB, urinary tract infection, pneumonia, and plague
Bacteria
Small particles that are incapable of living independently. Contain genetic genetic material (RNA or DNA) and typically live and reproduce within another living cell. Cause most common colds and HIV
Viruses
Small, plant-like organisms, such as yeast. Cause many conditions like athlete’s foot, jock itch, and valley fever
Fungi
A single-cell animal-like microorganisms such as amoeba and plasmodium. Exposure can cause malaria
Protozoans
Unsegmented worms that are tapered at both ends and include roundworms, pinworms, and hookworms. Exposure is known to cause intestinal or skin disease.
Nematodes
Abnormal proteins, previously believed to be incapable of a free-living existence, somehow survive independently and transmit disease from person to person. No nucleus but can multiply. Example is mad cow disease
Prions
The nasopharynx extends from?
Internal nares to the uvula
The oropharynx extends from the
Uvula to the epiglottis
