Based on the structural body plan, there are five different levels of the organisation that have been studied in the human body, namely, cellular level, tissue level, organ level, and organ system level, and organism level of body organisation. i _ { f } The body is made of many different cell types, each with a particular function, (for example muscle cells contract to move something, and red blood cells carry oxygen). 10. Cells are the smallest unit of all living things. Except where otherwise noted, textbooks on this site WebFigure 3. Atoms combine to form molecules. Name the six different levels of structural organization in the human body and explain their relationships. If the blades are originally at rest and begin to turn with a constant angular acceleration of $\alpha_c=0.5 \mathrm{rad} / \mathrm{s}^2$, determine the magnitude of the velocity and acceleration of points $A$ ($20$ ft from the vertical axis) and $B$ ($10$ ft from the vertical axis) on the blade when $t=4 \mathrm{~s}$. In humans, as in all organisms, cells perform all functions of life. Units of one type of cell that do a job. Chemical level this is the simplest level where it involves the building blocks of matter called atoms. To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms and molecules. The nervous system consists of the brain, spinal cord, sense organs, and nerves and functions by sensing information gathered by the sense organs and nerves and processing data in the brain and spinal cord. Our mission is to improve educational access and learning for everyone. All living structures of human anatomy contain cells, and almost all functions of human physiology are performed in cells or are initiated by cells. LEVELS OF STRUCTURAL ORGANIZATION The human body contains multiple levels of structural organization: chemical, cellular, tissue, organ, organ system and organism levels. Why or why not?

The cardiovascular system is essential for distributing oxygen and nutrients to cells all over the body. Hepatocytes, or liver cells, have lots of smooth endoplasmic reticulum to help the liver detoxify the body. A cell is the smallest independently functioning unit of a living organism. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life. Even though the human body is incredibly complex, it does have an underlying less complicated organisation. 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. The organism level is the highest level of organization. Cells are the smallest independent living thing in the human body. In multicellular organisms, including humans, all cells, 1 .
