Slide 2 Slide 3 Essential Questions How is the human body organized? What are the structural components of the body? How does the bodys structural organization relate to its support and movement? 2 1.01 Remember structural organization Slide 4 Composed of: 3 1.01 Remember structural organization Slide 5 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. 4 1.01 Remember structural organization Slide 6 Squamous Cuboidal Columnar 5 1.01 Remember structural organization Slide 7 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.) 6 1.01 Remember structural organization Slide 8 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 Slide 9 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. Slide 10 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 Slide 11 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. Slide 12 Connective tissue supports and connects organs and tissue Adipose type of connective tissue that stores fat cells. Cartilage firm, flexible support of the embryonic skeleton and part of the adult skeleton. Tendons white bands of connective tissue attaching skeletal muscle to bone. Ligaments strong, flexible bands of connective tissue that hold bones firmly together at the joints. Blood/Lymph liquid blood tissue and lymph tissue. Bone hardened bone tissue that supports and protects body. 11 1.01 Remember structural organization Slide 13 Connective tissue Adipose FibrocartilageElastic cartilage 12 1.01 Remember structural organization Slide 14 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 by granulation. Cicatrix Scar tissue Slide 15 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 14 1.01 Remember structural organization Slide 16 Muscle tissue Cardiac Skeletal Smooth 15 1.01 Remember structural organization Slide 17 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.
