Q

What is the internal environment?

A
  1. refers to the conditions and parameters within the body that are tightly regulated to maintain optimal functioning of
    - cells
    - tissues
    - organs
    - systems
  2. includes various factors such as
    - temperature
    - pH
    - concentration of ions (e.g. sodium, potassium, calcium)
    - concentration of nutrients (e.g. glucose, amino acids)
    - concentration of gases (e.g. oxygen, carbon dioxide)
    - fluid balance (hydration status)

Q

homeostasis

A
  • homeostasis plays a critical role in maintaining the internal environment of the body
  • by regulating various physiological parameters
  • dynamic maintenance of composition, temperature and pressure of the internal environment
  • essential condition for the organism’s survival
