Cornell Notes: Organization of the Body How the body is organized: AKA Levels of Organization 1. Cells 2. Tissues 3. Organs 4. Organ systems 5. (organism) Tissue: cells working together with a common purpose Four main types: 1. connective tissue 2. muscle tissue 3. epithelial tissue 4. nervous tissue. Organs: tissue working together with a common purpose Examples: heart, brain, lungs, “guts”, eyes, ears, skin Organ Systems: organs working together with a common purpose Eleven Organ Systems in the human body 1. Nervous System- controls body functions, detects information from the environment. 2. Respiratory System- takes in oxygen and eliminates carbon dioxide 3. Digestive System- breaks down food and absorbs nutrients 4. Excretory System- gets rid of waste 5. Skeletal System- supports and protects the body 6. Muscular System- allows movement of body and internal organs 7. Circulatory System- transports materials to and from cells 8. Endocrine System- controls many body processes with chemicals 9. Lymphatic System- “immune system” that helps fight disease 10. Integumentary System: protects the body (skin, hair, nails) 11. Reproductive System: allows new generation to be created
