Ch.1&2 Review Flashcards
Definition of physiology
Study of how the body and it’s parts WORK and FUNCTION.
Relationship between anatomy and physiology
Each part of your body has a job; the STRUCTURE DETERMINES what FUNCTIONS can take place.
Levels of organization
Atom (form) Molecules (make-up) Cell (all organisms have 1 or +) Tissue (form) Organ (make-up) Organ Systems (make-up) Organism

8 life functions (MMMRREDG)
Maintain balance Movement Metabolism Responsiveness Reproduction Excretion Digestion Growth
2 types of metabolism
Anabolism: putting together (amino acids->proteins)
Catabolism: breaks down(hamburger->amino acids(digestive) )
