Inflammatory response is characterized by 5 signs:
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?
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?
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
