An organ system forms an organism.
The whole setup is, from smallest to largest, is
Organelle
Cell
Tissue
Organ
Organ System
Organism
That is the organismal level. Many organisms have several organ systems.
Cells of the same type form tissues. Different tissue types form organs. Different organs form organ systems. Organ systems form an organism.
An organ. Then organs form organ systems.
similar cells work to produce tissues then tissues work together to form organs then organs work together to form organ systems then organ systems work to form organisms!
Organ systems
A group of different organ systems forms a complex organism, such as fish and mammals.
tissues combine to form an organ. few organs combine to form an organ system.few organ systems combine to form an organism.....
Organ
A group of similar cells that perfrom a common function form a tissue. A group of similar tissues that perform a common function form an organ, organs form organ systems, and organ systems form organisms.
The most simple are the cells. They form tissues and different tissues form organs. Different organs form organ systems and all the organ systems together form an organism like you.
An organ. Then organs form organ systems.
Organ systems are formed by cells that form tissues, these tissues form organs, and these organs form organ systems. Organ systems are groups of organs that work together to preforms biological functions, such as the circulatory and urinary systems.
