organismic level

enumerate the levels of structural organization (in order)

organismic level

the highest level of organizational structure where all parts of the body are functioning with another to comprise the total organism

-integumentary

- skeletal

- muscular

- nervous

- endocrine

- circulatory

- lymphatic/immune

- respiratory

- digestive

- urinary

- reproductive

enumerate the 11 systems of human body

system level

the level where different organs are joined together to form a body system: consists of several related organs that have common function

organ level

it is where different kinds of tissues are joined to form an organ

-epithelial tissue

- muscle tissue

- connective tissue

- nervous tissue

4 types of tissue in the body

tissue level

it is the level in which different cell types cells are joined together to form tissue

cellular level

the next higher level of organization; it yields from the combinations of molecules from the chemical level

cellular level

the next higher level of organization; it yields from the combinations of molecules from the chemical level

vitamins and minerals

catalyzes metabolic reactions

proteins

for muscle growth and repairs

fats

also provides energy and forms adipose tissue

carbohydrates

includes sugars, starches, glycogen, and cellulose

molecule

the chemical combination of 2 or more atoms

C,H,O,N,Ca,K,Na

elements that are essential for maintaining life:

1. atoms

2. molecules

3. macromolecules

4. organelles

5. cells

6. tissues

7. organs

8. organ systems

9. organism

levels of organization of living things:

organism

an entire living thing

organ systems

a group of organs that work together to perform a major function

organs

when a bunch of different types of tissues work together, they form:

tissues

cells that are similar in structure and function are usually joined together to form:

cell

organelles are part of this. it is the building block of living things. this is the level where life begins

organelles

macromolecules work together to form small parts called:

large

meaning of macro

macromolecules

molecules joined together by chemical bonds; when they join together, they make larger molecules called:

molecules

a group of atoms put together are called:

atoms

the smallest non-living unit to build a living thing.

Chemical level

is the lowest level of organization; includes atoms and molecules that are essential in maintaining life
