Organ systems of a human
Cells, tissues, organs and organ systems Multicellular organisms are organised into increasingly complex parts. In order, from least complex to most complex: cells, tissues, organs, organ systems, organism
Tissues
Animal cells and plant cells can form tissues, such as muscle tissue in animals. A living tissue is made from a group of cells with a similar structure and function, which all work together to do a particular job. Here are some examples of tissues: muscle, the lining of the intestine, the lining of the lungs
Organs
An organ is made from a group of different tissues, which all work together to do a particular job. Here are some examples of organs: heart, lung, stomach, brain, leaf, root
Organ systems
An organ system is made from a group of different organs, which all work together to do a particular job. Here are some examples of organ systems: circulatory system, respiratory system, digestive system, nervous system, reproductive system
