  1. Bellwork • Monday: Can you list the levels of structural organization of the human body in order from smallest to largest? Hint: It was your first drawing you completed on your title page. (Organ Systems, Cells, Organs, Tissues) Make sure you have your homework and Table of Contents filled in (look to your left) when you finish your bellwork! 

  3. The human body is divided into specific levels of organization and that these levels are what make the human body a complex organism. The levels of organization, from the simplest level to the most complex are: Structural Organization of the Human Body Cells…..Tissues.....Organs.....Organ Systems

  4. Cells • · The basic 1)________ of structure and function within the human body. • · Though all cells perform the processes that keep humans alive, they also have 2)__________ functions as well. • · Examples may be nerve cells (neurons), blood cells, epithelial cells and bone cells.

  5. What type of cells are these?

  6. Tissues • · A group of specialized cells that work together to perform the same function. There are 3) _______ basic types of tissue in the human body: • A) Nerve tissue—carries impulses back and forth to the brain from the body • B) Muscle tissue (cardiac, smooth, skeletal)—contracts and shortens, making body parts move • C)Epithelial tissue—covers the surfaces of the body, inside (as lining and/or covering of internal organs) and outside (as layer of skin) • D)Connective tissue—connects all parts of the body and provides support (for example tendons, ligaments, cartilage)

  7. Nerve Tissue—carries impulses back and forth to the brain from the body

  8. Muscle Tissue

  9. Epithelial Tissue:covers the surfaces of the body, inside (as lining and/or covering of internal organs) and outside (as layer of skin)

  10. Connective Tissue: connects all parts of the body and provides support (Ex: tendons, ligaments, cartilage)

  11. BellworkWhat tissues are represented below.. 2. 1. 4. 3.

  12. Organs • ·A group of two or more different types of tissue that work together to perform a specific function. • · The task is generally more complex than that of the tissue. • · For example, the heart is made of 4) _________ and connective tissues which function to pump blood throughout the body.

  13. Usually organs are made of multiple types of tissues.

  14. Organ Systems • · A group of two or more organs that work together to perform a specific function. • · Each organ system has its own function but the systems work together and depend on one another. • · There are eleven different organ systems in the human body: 5)_respiratory_, digestive, • endocrine, excretory (urinary), immune, integumentary (skin), muscular, nervous, • reproductive, 6)_cardiovascular/circulatory_, and skeletal.

  15. Review • What are the levels of structural organization of the human body. • Give an example of each level. • Which tissue contracts and shortens, moving body parts? • Which tissue connects all parts of the body? • Which tissue carries impulses back and forth? • Which tissue covers the external and internal surfaces of the body?
