  2. 1.01 Remember the body’s structural organization Essential Questions • How is the human body organized? • What are the structural components of the body? • How does the body’s structural organization relate to its support and movement? 1.01 Remember structural organization

  3. Organization of the human body:Tissues Composed of: 1.01 Remember structural organization

  4. Types of tissues: • Epithelial tissue-protects by covering internal and external surfaces and produces secretions. • Connective tissue-supports/connects organs & tissues. • Muscle tissue-cells have ability to contract/move body. • Nervous tissue-cells react to stimuli/conduct impulses. 1.01 Remember structural organization

  5. Epithelial TissuesProtect body surfaces by providing both an internal and external covering or layer.Epithelial cells can be found in different forms: SquamousCuboidal Columnar 1.01 Remember structural organization

  6. Epithelial Tissues Can be found in organs and in glands: In small intestines ET can absorb nutrients In glands ET can secrete hormones & enzymes In skin ET can excrete sweat. (All glands are made of epithelial tissue.) 1.01 Remember structural organization

  7. MEMBRANES – • formed by putting two thin layers of tissue together, cells may secrete a fluid • Membranes are vital  because they separate the cell from the outside world.  They also separate compartments inside the cell to protect important processes and events. • Membranes are Epithelial or Connective

  8. Epithelial Membranes: 2 classes 1. MUCOUS MEMBRANES– lines digestive, respiratory, reproductive and urinary systems – produces mucous to lubricate and protect the lining • They line various body cavities that are exposed to the external environment and internal organs. • 2. Serous Membranes– double-walled membranes produces a watery fluid (Serous fluid)lines closed body cavities • Pleural, Pericardial, Peritoneal • the outer part of the membrane that lines the cavity is the PARIETAL membrane • the part that covers the organs is the VISCERAL membrane.

  9. Serous Membranes… PLEURAL MEMBRANE – lines thoracic or chest cavity and protects the lungs PERICARDIAL MEMBRANE – lines the heart cavity and protects the heart PERITONEAL MEMBRANE – lines the abdominal cavity and protects abdominal organs The watery/serous fluid produced allows organs to move freely and prevents friction

  10. Connective Membranes • Are made of two layers of connective tissue. Synovial membrane-Lines the joint cavity and produces synovial fluid which prevents friction with movement of the bones.

  11. Organization of the human body:Tissues Connective tissue supports and connects organs and tissue • Adiposetype of connective tissue that stores fat cells. • Cartilagefirm, flexible support of the embryonic skeleton and part of the adult skeleton. • Tendonswhite bands of connective tissue attaching skeletal muscle to bone. • Ligamentsstrong, flexible bands of connective tissue that hold bones firmly together at the joints. • Blood/Lymphliquid blood tissue and lymph tissue. • Bonehardened bone tissue that supports and protects body. 1.01 Remember structural organization

  12. Organization of the human body:Tissues Connective tissue Adipose Fibrocartilage Elastic cartilage 1.01 Remember structural organization

  13. Tissue Repair! • Repair of damaged tissue occurs continually. • Two types • Primary takes place in clean wound where infection is not present. • Secondary larger and deeper wounds. Takes place bygranulation. • Cicatrix –Scar tissue

  14. Organization of the human body:Tissues Muscle tissue contracts and moves a body part • Cardiac • striated, involuntary • contracts the heart • Skeletal • striated, voluntary • attached to the skeleton • Smooth • nonstriated, involuntary • provides movement in various body systems 1.01 Remember structural organization

  15. Organization of the human body:Tissues Muscle tissue Cardiac Skeletal Smooth 1.01 Remember structural organization

  16. NERVOUS TISSUE • – cells that react to stimuli and conduct an impulse • Neurons are highly specialized cells that generate and transmit electrical impulses (action potentials) permitting rapid communication between distant areas of the body.
