Notes: Body Function and Organization What are the 5 levels of cellular organization? Compare/ contrast cells, tissues, organs and organ systems.

Notes: Body Function and Organization Levels of Cellular organization: Cell  tissue  organ  organ system  organism

Notes: Body Function and Organization Levels of Cellular organization: Cell  tissue  organ  organ system  organism Example: bone  connective  bone  skeletal  person cell tissue system

celltissueorganorgan systemorganism Cells are microscopic and contain organelles. (ribosomes, mitochondria, nucleus….) Organelles are cell structures that carry out the processes which keep organisms alive.

celltissueorganorgan systemorganism A tissue is formed when many of the same type of cells work together. There are four basic types of tissue: muscle tissue nervous tissue connective tissue epithelial tissue

celltissueorganorgan systemorganism Organs can be composed of many different types of cells and tissues. Living things may be similar or they may have unique organs that allow them to survive in their habitat. Examples:

celltissueorganorgan systemorganism Organs can be composed of many different types of cells and tissues. Living things may be similar or they may have unique organs that allow them to survive in their habitat. Examples: heart, lungs, wings, ears, echolocation ‘radar’, roots, leaves, seeds

celltissueorganorgan systemorganism When different organs work together an organ system is created. Each organ system has specific functions in order to maintain homeostasis.
