levels of organization

chemical —> cellular —> tissue —> organ —> system —> organismal

chemical

atoms combined to form molecules; e.g. macromolecules (carbohydrates, proteins, lipids, nucleic acids)

cellular

molecules combine to form cells

tissue

similar cells working together to form tissues

organ

different tissues working together for a common purpose to form organs

system

different organs that work closely together for a common purpose

organismal

made up of the organ systems to accomplish life functions

needs for life

1. heat

2. pressure

3. food

4. oxygen

5. water

pressure

FORCE that creates a pressing action. 

Atmospheric -  oxygen —> lungs —> blood

 Hydrostatic (blood, body fluids, into and out of cells, intracellular fluids between cells)

heat

Reactions occur  at optimal temperatures (98.6’F)

Heat can increase or decrease reaction rates.

food

Chemicals used for:

Burning (energy requirements)

Building (new cells and molecules)

water

Environment for reactions to take place.

Involved IN reactions

Transports material

Regulated body temperature.

oxygen

Required for the release of ENERGY from FOOD to generate ATP’s.

reproduction

MITOSIS- cell division for repair, growth and replacement

MEIOSIS- production of cells for sexual reproduction

movement

External - to find food, water, survival

Internal- transport of  food, water, oxygen.

responsiveness

irritability; e.g. loud sounds, hot stove, bright lights, thirst

assimilation

changing absorbed materials into new forms/molecules

digestion

food breaks down into usable forms

absorption

transport of foods or fluids across membranes and into cells for use

respiration

generates energy; internal, external, and ventilation

circulation

movement of materials through water or fluid

growth

development and maturation of cells and their functions

excretion

waste removal; exocytosis, exhalation, urination

metabolism

sum of all the chemical reactions and processes in the body
