Solution Body organization: Six general levels of the organization listed from smallest to largest are chemical, cellular, tissue, organ, organ system, and organism levels.Chemicals are regarded to be the smallest and lowest unit of organization in a living system, ranging from the smallest atoms to the largest macromolecules. A cell is the tiniest, self-contained unit of a living creature that conducts or begins nearly every activity of human physiology.A tissue is a collection of numerous comparable cells that work together to execute a certain function.An organ is a bodily structure made up of two or more tissue types that are anatomically separate. An organ system is a collection of organs that operate together to carry out significant functions or meet the body's physiological requirements. The organism level is the highest level of organization.

This question is asking us to place these four key terms, tissues, cells, organ systems, and organs, in order from smallest to largest. The four terms in question represent four of the levels of biological organization. We’re being asked to rank them from smallest to largest or from least complex to most complex. In order to rank these terms, we’ll use this chart and this definition. A blank is a group of blank that work together to perform a specific function. The only term that doesn’t fit this definition is the cell, which we know is the basic unit of life. And since that means it’s the smallest thing that can be considered to be independently alive, we know that the term cell goes in the smallest spot on our chart. Now, we have three more terms to place. Next, let’s try to place the term tissues. A tissue is a group of cells that work together to perform a specific function. So, we know where to place tissue in our levels of biological organization chart, directly above cells. Next, let’s try organ systems. An organ system is a group of organs that work together to perform a specific function. Since we didn’t say it’s a group of tissues, we’ll go ahead and skip a space and put it at the top of our levels of biological organization chart. Let’s go ahead and define our last term organs. An organ is a group of tissues that work together to perform a specific function. Since we know that tissues make organs and organs make organ systems, we know exactly where to place the term organ in our levels of biological organization chart. Using the definition of each term and this handy organizational chart, we’re ready to answer our question. The order of these structures from smallest to largest is cells, tissues, organs, organ systems. Theme 1: What Makes Us Unique? *Before you begin to study the different structures and functions of the human body, it is helpful to consider its basic architecture; that is, how its smallest parts are assembled into larger structures. It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms and biosphere (Figure 1). Levels of Structural Organization of the Human Body  *The Levels of OrganizationTo study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of which are hydrogen, oxygen, carbon, nitrogen, calcium, and iron. The smallest unit of any of these pure substances (elements) is an atom. Atoms are made up of subatomic particles such as the proton, electron and neutron. Two or more atoms combine to form a molecule, such as the water molecules, proteins, and sugars found in living things. Molecules are the chemical building blocks of all body structures. A cell is the smallest independently functioning unit of a living organism. Even bacteria, which are extremely small, independently-living organisms, have a cellular structure. Each bacterium is a single cell. All living structures of human anatomy contain cells, and almost all functions of human physiology are performed in cells or are initiated by cells. A human cell typically consists of flexible membranes that enclose cytoplasm, a water-based cellular fluid together with a variety of tiny functioning units called organelles. In humans, as in all organisms, cells perform all functions of life. A tissue is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function. An organ is an anatomically distinct structure of the body composed of two or more tissue types. Each organ performs one or more specific physiological functions. An organ system is a group of organs that work together to perform major functions or meet physiological needs of the body. Figure 2 shows some of the organ systems of the body that we will consider over the course of this semester. Many organs have functions integral to more than one organ system. Organ Systems of the Human Body The organism level is the highest level of organization considered in anatomy/physiology. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life. In multicellular organisms, including humans, all cells, tissues, organs, and organ systems of the body work together to maintain the life and health of the organism. *Section SummaryLife processes of the human body are maintained at several levels of structural organization. These include the chemical, cellular, tissue, organ, organ system, and the organism level. Higher levels of organization are built from lower levels. Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms. *Glossarycellsmallest independently functioning unit of all organisms; in animals, a cell contains cytoplasm, composed of fluid and organellesorganfunctionally distinct structure composed of two or more types of tissuesorgan systemgroup of organs that work together to carry out a particular functionorganismliving being that has a cellular structure and that can independently perform all physiologic functions necessary for lifetissuegroup of similar or closely related cells that act together to perform a specific functionWhich is the correct order of organization of the human body?Summarizing: The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
