Structural Organization
Organisms-
Systems-
Organs-
Tissue-
4 types of cells-
cellular-
chemicals- -
-all of the systems functioning together
-made of related organs with the same function
ex:digestive, circulator, muscular, nervous
-tissues joined together
-made up of a group of cells
-epithelial, muscle, connective, nervous
-made of molecules
-all chemical needed to maintain life
ex:C, H, O, N, Ca, K, Na - Metabolism
- all chemical process that occurs in the body
- catabolism
-
breakdown of large complex molecules to smaller simpler ones
ex: protein split into amino acids - Anabolism
-
uses the energy from catabolism to build the body's strucual or functional components
ex: syntesis of protein needed for muscle and bone - Responsiveness
-
ability to detect and respond to changes in the external environment
ex: nerves respond to electrical impulses - Movement
- motion of whole body, individual organs or single cells
- Growth
- increase in size or number of cells
- differentation
-
process where unspecialized cells become specialized
ex: eggs and sperm become an ovum - Reproduction
- formation of new cells for growth, repair, or replacement or the production of a new individual
