3 important questions on Introduction to Physiology and Homeostasis - Concept of Homeostasis - Body cells are in contact with a privately maintained internal environment
What terms are used for the fluid that is not in the cells but surrounds the cells and what are the 2 components of this fluid?
Extracellular environment / internal environment
plasma, the fluid portion of the blood & the interstitial fluid, which surrounds and bathes the cells

How do body systems transport nutritents and O2 into the internal environment? Provide examples of body systems.
Body systems transport nutrients and O2 from the E.E --> I.E
digestive system = nutrients from E.E --> plasma
respiratory system = O2 from E.E --> plasma
circulatory system = nutrients + O2 --> internal environment
digestive system = nutrients from E.E --> plasma
respiratory system = O2 from E.E --> plasma
circulatory system = nutrients + O2 --> internal environment
Provide the typical route of how body cells remove waste into the external environment
Waste from cell --> I.E --> plasma --> specialised organs --> external environment
