Lymph/
Immune Cells
Immune Cells
the main cells in the lymphatic system
lymphocytes
Grape-like sacs for gas exchange in the lungs
alveoli
These prevent entry of foreign substances via skin, hair/sebaceous glands, and mucous membranes
Physical Barriers
Cells responsible for antibody-mediated immunity
B Cells
Most abundant element in the air we breathe
Nitrogen
This agranulocyte is a highly phagocytic scavenger
monocytes
Organ with both lymphatic and hematologic functions.
The spleen
This increases redness, swelling, and heat in localized tissue
Inflammation
Which T cell is responsible for ending the immune response?
Regulatory T Cells
Compare internal respiration to external respiration
external respiration= gas exchange between blood and air
internal respiration= gas exchange between blood and tissues in the body
This granulocyte is the most common, and the first to arrive to injury
neutrophils
The main ducts of the lymphatic system
Right lymphatic duct and Thoracic duct
This completes the actions of antibodies and phagocytes
Complement System
Which exposure takes time to produce antibodies to neutralize the antigen
primary
What is the stimulus for increasing exhalation?
carbon dioxide
This granulocyte is the least common type of WBC, and releases histamines & responds to allergies
basophils
2 areas of brain that control respiration
medulla oblongata & pons
These are a natural antiviral and coordinate response with other defenders
Which T cell recognizes and destroys foreign cells?
Cytotoxic T cells
What is the purpose of surfactant in the alveoli?
Decreases the surface tension, and keeps the sacs open
