Diaphragm
What are the function of the Respiratory system?
Transportation of gasses (oxygen and carbon dioxide)
Phonotation
Olfactory sensation to CNS
What is the common tube of the airways?

Thermoregulation
What are the components of the Lymphatic system?
Lymphatic vessels, nodes and tonsils
Spleen, thymus and bone marrow
What are the functions Lymphatic System?
Transportation
Circulation and modification of tissue fluid
Defends against infection and disease
Where does the Lymphatic system get its fluid from?
Cells produce extra fluid which goes into the lymphatic system to help fight against infection and disease

What are the functions of the Endocrine system?
Long term regulation of other organ systems
What are the Glands of the Endocrine system?
Pituitary, Thyroid, Parathyroid and Adrenal glands
What are the double agents of the Endocrine system?
Liver and Pancreas
Why are the Liver and Pancreas double agents?
Because they function in the GI system and Endocrine system
