Study Notes
Systems
- A system is an object or a group of objects.
- Open systems allow the exchange of both matter and energy. Examples include open bottles.
- Closed systems allow only the exchange of energy. Examples are bottles with lids.
- Isolated systems do not allow the exchange of matter or energy. Examples include insulated systems.
- Systems can be biological, physical, or chemical.
Changes During Physical Activity
- Body Temperature: Increases due to exothermic respiration.
- Heart Rate: Increases to supply more oxygen and nutrients for respiration.
- Breathing: Becomes deeper and faster for increased oxygen intake.
- Muscle Ache: Caused by lactic acid produced during anaerobic respiration.
- Shortness of Breath: Faster, shorter breaths bring in more oxygen.
- Sweating: Regulates body temperature.
- Blood Pressure: Increases to efficiently deliver oxygen and nutrients to muscles and organs.
