1.2 Structural And Functional Organization Of The Human Body Flashcards
11 organ system
- urinary system
- integumentary
- skeletal
- muscular
- nervous
- endocrine
- cardiovascular
- lymphatic
- respiratory
- digestive
- reproductive
The body can be studied at six levels of organization:
- chemical level
- cell level
- tissue level
- organ level
- organ system level
- whole organism level
This level involves interactions between atoms , which are tiny building blocks of matter .
Chemical level
The basic structural and functional units of all living organisms
Cell
Molecules combine to form
Organelles
Small structures that make up cells
Organelles
Composed of a group of cells and the materials surrounding them that could determine the function of
Tissue
Classify the four basic types of muscles
- epithelial
- connective
- muscle
- nervous
Composed of two or more tissues type that perform one or more common functions
Organ
Group of organs that together perform a common function or set of functions and are therefore viewed as a unit.
Organ system
Any living organism or thing is considered as a whole-whether composed of one cell such as bacterium or trillions of cells such as human
Organism level/organism
Kind of organism that is a complex of organ , mutually dependent on one another
Human organism
