levels of organization of human body structure

 In this article, we will look at the levels of organization of human body structure and function. Starting from the chemical level and ending with the organism level.

Levels of organization of human body

 How are body parts organized and how do they work well together?.  In order to understand the human body and anatomy, it is a good idea to divide things into levels.


We’ll look at 7 levels of regulation of body structure and function.


The first level is the chemical level, and begins with the atoms that make up everything physical in the universe, including our bodies. 


Atoms can bond together to form molecules, which are larger chemical groupings, and molecules can unite with other molecules and more atoms than large molecules.



 The next level of organization in the body is the level of the organelle. Organelles are made of chemical assemblies and are as small as the things in cells. 


Organelles have specific functions in cells, and cannot live outside cells, and without organelles, cells cannot survive.



The cellular level is next. Cells are the smallest unit in the body that exhibit the basic characteristics of life.


It is estimated that the body contains about 100 trillion cells. and each cell consists of a membrane, a nucleus, and a cytoplasm.. containing the organelles necessary for the cell to function properly. 


There are many different types of cells in the body, that perform different functions in the body.


tissue level

The next level is the tissue level.  Tissue is a collection of similar cells that have arisen from the same part of the embryo.


all of which perform a specific function. Tissue cells are surrounded by matrix, or non-living material between cells.


There are 4 main types of tissues in the body, they are “connective tissue, muscle tissue, nerve tissue and epithelial tissue”.


 Next is the device level: Organs are made up of different types of tissues that together can perform different functions in the body. 


For example, the liver, which is an organ in the abdominal area of ​​the body. stores some vitamins and minerals, stores glycogen, which is a form of stored energy.


helps destroy old red blood cells, and helps remove toxins from the blood.  To get rid of harmful substances.

system level 

 The next level of organization in the body is the system level.  Systems are made of organs, which by working together can perform more complex types of functions in the body. 


There are 11 major organs in the human body.  The systems often work together to fulfill the different needs of the body. such as the respiratory system that takes in oxygen.


the cardiovascular system transports the oxygen to different parts of the body.


 The seventh and final level is the level of the organism. The total human being consists of all the previous levels, that we just covered.  


that the levels of regulation of the body’s structure and function. Hence, we have concluded our article.
