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. An organ system is a group of organs that work together to perform major functions or meet physiological needs of the body. Molecules are the chemical building blocks of all body structures. Wish in a little way i can help you undertand. system level or organ-system level. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life. That means we are made of lots of cells, not just one cell. Individual cells may have some common functions but vary widely in size and shape. Humans are multi-cellular animals. Organs that work together are grouped into organ systems. Each tissue has a characteristic role within the human body which we will discuss later. The human body has 6 main levels of structural organization. Even bacteria, which are extremely small, independently-living organisms, have a cellular structure. Organ level– an organ is a structure composed of at least two different tissue types that perform a specific function within the body.

For instance, the heart and blood vessels work together and circulate blood throughout the body to provide oxygen and nutrients to cells. When one or more atoms joined together, they form a chemical structure called a molecule, with one or more chemical bonds holding the molecule together. For instance, the heart and blood vessels work together and circulate blood throughout the body to provide oxygen and nutrients to cells. Even though the human body is incredibly complex, it does have an underlying less complicated organisation. Chapter 1: An Introduction to the Human Body. Levels of organization in the human body. 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.

Organs that work together are grouped into organ systems. Complex functions begin to emerge at this level. 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. The human body consists of trillions of cells, each capable of growth, metabolism, response to stimuli, and, with some exceptions, reproduction. The cells in many multi-cellular animals and plants are specialised, so that they can share out the processes of life. 3-Describe the levels of structural organization of the human body.
