Organization of the Human Body Lesson Overview Organization of the Human Body Organization of the Body The levels of organization in the body include cells, tissues, organs, and organ systems. At each level of organization, these parts of the body work together to carry out the major body Lesson Overview Organization of the Human Body Cells A cell is the basic unit of structure and function in living things. Specialized cells, such as bone cells, blood cells, and muscle cells, are uniquely suited to perform a particular function. Lesson Overview Organization of the Human Body Tissues Next level up the organization is tissue. Consists of a group of cells. Lesson Overview Organization of the Human Body Epithelial Tissue The tissue that lines the interior and exterior body surfaces is called epithelial tissue. Your skin and the lining of your stomach are both examples of epithelial tissue. Lesson Overview Organization of the Human Body Connective Tissue Tissue that provides support for the body and connects its parts is connective tissue. This type of tissue includes fat cells, bone cells, and even blood cells. Many connective tissue cells produce collagen, a long, tough fiber-like protein that is the most common protein in the body. Bone Lesson Overview Organization of the Human Body Nervous Tissue Nerve impulses are transmitted throughout the body by nervous tissue. Neurons, the cells that carry these impulses, examples of nervous tissue. Lesson Overview Organization of the Human Body Muscle Tissue Movements of the body are possible because of muscle tissue. Some muscles are responsible for the movements you control, and some you cannot control, such as the tiny muscles that control the size of the pupil in the eye. Lesson Overview Organization of the Human Body Organs A group of different types of tissues that work together to perform a single or several related functions is called an organ. For example, the eye is an organ made up of epithelial tissue, nervous tissue, muscle tissue, and connective tissue. Lesson Overview Organization of the Human Body Organ Systems An organ system is a group of organs that perform closely related functions. For example, the brain and spinal cord are organs of the nervous system. The organ systems interact to maintain homeostasis in the body as a whole. Lesson Overview Organization of the Human Body The organ systems, along with their structures and main functions, are shown below. Lesson Overview Organization of the Human Body The organ systems, along with their structures and main functions, are shown below. Lesson Overview Organization of the Human Body The organ systems, along with their structures and main functions, are shown below. Lesson Overview Organization of the Human Body The organ systems, along with their structures and main functions, are shown below. Lesson Overview Organization of the Human Body The organ systems, along with their structures and main functions, are shown below. Lesson Overview Organization of the Human Body The organ systems, along with their structures and main functions, are shown below. Lesson Overview Organization of the Human Body The organ systems, along with their structures and main functions, are shown below.
