make them non-living**
3. Responsiveness -> BIG ONE -> how we human response to changes -> important to keep us alive
4. Movement -> change in position of the body or a body part; motion of an internal organ
5. Respiration -> release of energy from food -> intake oxygen, release CO2
6. Digestion -> breakdown of food which are then absorbed into blood
7. Circulation -> movement of cells and chemical
8. Excretion -> remove of metabolic wastes
Maintenance of Life
- Water -> we are around ~60% water (depends if male or
female)
o Transport stuff in the body done by the blood
o Required for metabolic process
o Provide environment for internal process
o Regulate body temperature
o Make up intracellular and extracellular fluids
- Heat -> comes from metabolic reaction; mainly from muscle cells
- Pressure -> forced applied to something
