Study Notes

The human body can be understood through seven levels of organization of body structure and function.
The first level is the chemical level, where atoms bond to form molecules and macromolecules.
The second level is the organelle level, where organelles with specific functions exist within cells.
The third level is the cellular level, where cells, estimated at 100 trillion in the body, have a membrane, nucleus, and cytoplasm.
The fourth level is the tissue level, where groups of similar cells, surrounded by a matrix, perform specific functions and are classified as connective, muscle, nervous, or epithelial tissue.
The fifth level is the organ level, where organs, made up of different tissues, perform complex functions in the body, such as the liver's role in storing vitamins, minerals, and detoxifying the blood.
The sixth level is the system level, where organs work together in systems, such as the respiratory and cardiovascular systems, to accomplish different needs of the body.
The seventh and final level is the organism level, where the overall human organism is made up of all previous levels.
