6. organ system
the correct order from the smallest to the largest is:

The  correct order from smallest to largest are: Molecule, Cell, Tissue, Organ, Organ system and Organism.

Explanation:

Molecule : They are very small particles or substance specially at both structural and cellular level. These are made up of two or more atoms which are held tightly by strong chemical bonds. The four important  molecules of life are proteins, carbohydrates, lipids and nucleic acids.Without any of these molecules,survival of organisms and cells  is very difficult. These molecules are very important in both the ways structurally as well as functionally.Cell :Cell is the most important, structural and functional unit of life. A cell is  blessed with a capacity to carry out the main functions like nutrition, excretion and respiration. Cell is the important membrane bound unit  that includes fundamental molecules of life of which all living organisms are made up of. A single cell is sometimes a complete organism in itself like bacterium or yeast. The four main types of cells are Epithelial cells, nerve cells,muscle cells and connective tissue cells.Tissue : A tissue is an assembly of similar cells and their extracellular matrix belongs to the same origin which combines together  and carry out a specific function. Organs are the formation of functional groups of multiple tissues.There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made up of special cells which are combined together depending on their structure and function. Example of connective tissue include fat & loose connective tissueOrgan : An organ is a self contained cluster or sets of tissues which perform a specialised functions in the body.Two or more organs are working together in order to perform a special body functions forming an organ system  also known as body system.When organs began to shut down, person will feel drowsy and starts losing consciousness. When the heart and lungs stop working body also dies. Heart rate changes. Pulse becomes fast or irregular.Organ System: An organ system is  a set/ cluster of organs which are working together to perform a certain function in the body of an organism.The 11 organ systems of the body are  integumentary, muscular, nervous, circulatory, lymphatic, respiratory, endocrine, urinary, reproductive and digestiveOrganism: It is a  creature like plant, animal or single cellular life form in comparison  to a living creature. They reacts to stimuli, reproduce  grow and also play a main role in homeostasis. It can be virus, bacteria, protist, fungi or animal.
