Metabolism | all chemical changes within cells considered together |
Homeostasis | state of balance in which the body's internal environment remains in the normal range |
Levels of Organization | 7 levels: 1) Chemical 2)Organelle 3) Cellular 4) Tissue 5) Organ 6) System 7) Organism |
Feedback Control Loops | controls homeostasis; controlled mainly by the nervous and endocrine systems |
Negative Feedback Loop | opposite, inhibitory, opposes change by creating a response that is opposite in direction to the initial disturbance, most common in the body |
Positive Feedback Loop | same, stimulatory, often dangerous, amplify/reinforce change |
3 basic components of a feedback control loop | 1) receptor 2) integrating/control center 3) effector mechanism |
Afferent | signal traveling towards a particular center or point of reference |
Efferent | moving away |
