|
redness, pain, heat, edema, loss of motion.
|
|
|
What are the functions of inflammation?
|
aids in disposal of antigens, toxins at injury site, prevents spread to other areas, site for tissue repair
|
|
|
What is phagocytosis?
|
white blood cells;
the ingestion of antigens by cells called phagocytes |
|
|
two types of phagocytes
|
neutrophils and monocytes or macrophages
|
|
|
which phagocyte is first to the wound?
|
neutrophil
|
|
|
macrophages are found in
|
lungs as dust cells, and liver as kupffer cells
|
|
|
what are the mechanisms of phagocytosis
|
chemotaxis, a chemical attraction of a phagocyte to a particular location
adherance, attachment of phagocyte to surface of antigen. ingestion of, which engulfs the antigen which usually destroys it within 10-30 min. |
|
|
what is defense system line three?
|
immune system
|
|
|
what are two characteristics of immune response?
|
specificity and memory.
specificity is where special markers are used for specific antigens. memory is where it lives forever. it knows exactly what type of antigen it is, forever. |
|
|
what is CMI? what does it do?
|
CMi is a type of immunity, cell mediated immunity, used for T-cells.
|
|
|
what are the cells used in CMI?
|
helper t-cells: they are suface markers
cytotoxic killer t-cells: destroy antigens by cytolysis supressor t-cells: inhibit proliferation of T/B cells Memory cells: recognizes antigens |
|
|
What is AMI?
|
Antibody mediated immunity. This is used for the B-cells, used for extracellular pathogens, bacteria
|
|
|
what are examples for active and passive immunity? what is active and passive immunity?
|
passive is when you are given someone else's Antibodies, active is when you make your own antibodies in response to an illness.
example: passive, mother baby, breast feeding active, chicken pox |
|
|
The respiratory system has four processes..what are they?
|
pulomonary ventilation: mechanicial/breathing/muscles/diaphram
external respiration: exhange of gases/alveoli and capillaries internal respiration: exhange of gases /capillaries and tissues cellular respiration: cells use of 02, metabolism |
|
|
what are the organs of the respiratory system?
|
pharynx, larnyx, trachea, bronchi and lungs
|
|
|
what are the functions of the nose?
|
warms and moistens
|
|
|
what are the three parts of the pharynx?
|
nasopharynx, oropharynx, larengeopharynx
|
|
|
what is called the voice box?
|
larynx
|
|
|
give the path of the bronchial tree
|
trachea, secondary bronchii, tertiary bronchii, bronchioles, terminal bronchioles, respiratory bronchioles, alveolar ducts, alveoli
|
|
|
what are the two types of lining in the lungs?
|
parietal pleura (outer), and visceral pleura (inner)
|
|
|
the lungs are separated into lobes
|
lobules are elastic CT, with three types of cells, simple squamous used for diffusion of oxygen and carbondioxide, septal cells which are blue,a and dust cells which are green
|
