Human Body
Concept: Organ Systems of Our Body
- An organ is made with a group of tissues that perform specific functions in the body.
- The human body is built up of several organ systems that regulate all bodily functions.
Levels of organisation in our body:
|
Cell : A cell is the smallest unit of life. It is the structural and functional unit of the human body. |
|
Tissue : A group of cells with similar structures and performing similar functions. |
|
Organ : It consists of a group of tissues that carry out a particular function. |
|
Organ System : A system consisting of a group of organs that work together to perform specific body functions. |
|
Organism : A living thing capable of performing all life processes with the help of the organ systems. |
