Cells are organized into tissues, and tissues form organs.

You cannot download interactives. Anorganis an anatomically distinct structure of the body composed of two or more tissue types. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Cells, the basic building blocks of the human body, make up tissues, which form specialized structures called organs. Atoms are made up of subatomic particles such as the proton, electron and neutron. Organs that work together are grouped into organ systems. Defend against infection and disease, moves lymph between tissues and the blood stream. 
The organism level is the highest level of organization. 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. Figure \(\PageIndex{3}\): Organ Systems of the Human Body (continued).
The smallest unit of any of these pure substances (elements) is an atom. Your organ systems do not work alone in your body. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. Higher levels of organization are built from lower levels. 
In humans, as in all organisms, cells perform all functions of life. 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. An organ is a group of tissues that constitutes a distinct structural and functional unit. tissue.

An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life. 
Life processes of the human body are maintained at several levels of structural organization. Each type of cell in the figure plays a specific role. These include the chemical, cellular, tissue, organ, organ system, and the organism level.

Do you know the functions of any of the cell types shown here? All living structures of human anatomy contain cells, and almost all functions of human physiology are performed in cells or are initiated by cells. For some people, gender identity is different from biological sex or their sex assigned at birth. WebWhat are the levels of structural organization? Thus, the heart is an organ composed of all four tissues, whose function is to pump blood throughout the body. By the end of this section, you will be able to: 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. Which organ system supports the body and allows it to move? A cell is the smallest independently functioning unit of a living organism. Higher levels of organization are built from lower levels. In fact, most organs contribute to more than one system. chemical Each organ performs one or more specific physiological functions. She or he will best know the preferred format. The organism level is the highest level of organization. 1. chemical, 2. cellular, 3. tissue, 4. organ, 5. organ system and 6. organismal level 1.

A number of organ systems, including the cardiovascular and respiratory systems, all work together to do this. Explain how form and function are related in human cells. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life. Molecules are the chemical building blocks of all body structures. All living structures of human anatomy contain cells, and almost all functions of human physiology are performed in cells or are initiated by cells. This book covers eleven distinct organ systems in the human body (Figure1.4andFigure1.5). Figure \(\PageIndex{2}\):Organ Systems of the Human Body Organs that work together are grouped into organ systems. 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. A tissue is a collection of similar, specialized cells. Acellis the smallest independently functioning unit of a living organism. 
An Each cell carries out basic life processes that allow the body to survive. Many human cells are specialized in form and function, as shown in Figure below. Why or why not? Chapter 1: An Introduction to the Human Body. Each machine consists of many parts, and each part does a specific job, yet all the parts work together to perform an overall function. A cell is the smallest independently functioning unit of a living organism. 
1) A. In the human body, not all cells look or work the same. Even bacteria, which are extremely small, independently-living organisms, have a cellular structure. Include examples.
