What does the thoracic (left lymphatic) duct drain?
Left side of head, neck, chest, left upper limb and entire inferior body
What structure receives lymph from the upper right side of body
Right lymphatic duct
What two things return lymph to heart
Skeletal mm
Respiratory pump
External physical and chemical barriers provided by the skin and mucous membranes
Innate (nonspecific) immunity
Most abundant antibody
IgG
Antibody found in sweat tears saliva and mucous, and breast milk
IgA
Antibody located on mast cells and basophils involved in allergic and hypersensitivity reactions ( parasitic worms)
IgE
