Organs are formed when several tissues that have the same structure and function work together in the human body. The main difference between tissues and organs is their functionality. The tissues can only do relatively simple tasks or activities, whereas, an organ is much more complex and is capable of performing many advanced processes and functions at a time.

Difference Between Tissues and Organs

Tissues

Organs

Tissues are composed of cells that share similar features and functionality

Organs are composed of several types of tissues

Has a relatively simple function to fulfill

Organs perform much more complex functions and roles

Tissues form the major structural component of organs

Organs form the major components of organ systems

Tissue repair happens by regeneration or fibrosis of necrotic or damaged tissues

Organs and organ systems heal when the integral tissues are repaired

Types of tissues in animals usually include connective tissues, muscle tissues, epithelial tissues and nervous tissues – Plants on the other hand have vascular tissues, ground tissues and epidermis

Types organ systems (and organs) include

Circulatory system (heart, arteries and veins), digestive system (stomach, intestines and liver), respiratory (lungs and diaphragm) etc

Conclusion:

Tissues are formed from cells that have the similar structure and functionality. Organs are formed from a variety of tissues and they exhibit more complex functions and features necessary for life.
