Have you ever taken a moment to consider how complex the human body is? In every complex system, there are levels of organization. As a health care administrator, understanding this organizational system will help you understand the building components of the human body and how it functions. We will look at these levels of organization in order of increasing complexity. These levels include:
Organelles
Cells
Tissue
Organs
Systems
Organelles are structures that are found within the cell that are responsible for building the cell. Each of these structures is responsible for a specific function in order for the cell to survive. Can you think of an example? How about the nucleus, one of the most important parts of a cell that contains the DNA.
Organelles are responsible for creating the cell. This is the most basic unit of life! Cells are considered the smallest living unit in the human body. The process of a cell divides and reproduces itself to create tissue. The tissue is created to carry out various functions in the body. A great example would be our muscles. Muscle tissue allows us to carry out physical functions. Remember all the cells of the body work together. In fact, our lives depend on it!
Now that we have formation of cells, what does it become? You said it, tissue! Tissue is created by identical cells and. As the tissue develops, it can be categorized into 4 basic types of tissue. Each type of tissue performs a specific function.
These four basic types of cells are
Epithelial tissue
Connective tissue
Muscle tissue
Nervous tissue
If we think back to the organelles, cells, and tissue, we’ve come a long way to now the level of organs. Tissues combine, normally two or more, to the creation of an organ. The tissues work together to perform a specific function. For example, think of your heart! The function of the heart is to contract and pump blood throughout the body.
Because of the multiple organs in our body, let’s just think about the organs as one specific organ system. This organ system carries out one specific functions that are necessary to sustain life. For example, when you think of the digestive system, you think of processing food and absorbing it. That should bring to mind the stomach and intestines, which are in fact major digestive organs.
