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 2 Composed of: 1.01 Remember structural organization 3 Types of tissues: Epithelial tissue Connective tissue Muscle tissue Nervous tissue 1.01 Remember structural organization 4 Epithelial Tissue protects the body by covering internal and external surfaces, and produces secretions Skin covers the outside of the body lines the inside of the body Membrane two thin layers of tissue that join together cells may secrete a fluid 1.01 Remember structural organization 5 Mucous Membranes: •Lines surfaces & spaces that lead to the outside of the body •Line respiratory , digestive, reproductive & urinary systems Serous Membranes: • Double walled membrane that produces a watery fluid & lines closed body cavities (fluid is called serous fluid) • Parietal Membrane: outer part that lines the cavity •Visceral Membrane: covers the organs within the cavity 1. a) b) c) Examples of membranes Pleural: lines thoracic cavity & protects lungs Pericardial: lines heart cavity& protects heart Peritoneal: lines abdominal cavity & protects abdominal organs 1.01 Remember structural organization 6 Synovial Membranes: •Lines joint cavities •Secretes synovial fluid which prevents friction inside the joint cavity 1.01 Remember structural organization 7 1.01 Remember structural organization 8 Epithelial tissues Squamous Cuboidal Columnar Line heart, blood & lymphatic vessels Line kidney, ovaries & some secretory glands Have cilia, cover digestive & parts of respiratory tract Pg 56 &57 (Table 4-1) 1.01 Remember structural organization 9 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 1.01 Remember structural organization 10 Connective tissue Adipose Fibrocartilage 1.01 Remember structural organization Elastic cartilage 11 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 12 Muscle tissue Cardiac Skeletal 1.01 Remember structural organization Smooth 13 Nervous tissue reacts to stimulation and conducts an impulse 1.01 Remember structural organization 14 Nervous tissue Neuron 1.01 Remember structural organization 15 1.01 Remember structural organization 16 1.01 Remember structural organization 17 1.01 Remember structural organization 18 Click here to hear heartbeat 1.01 Remember structural organization 19 1.01 Remember structural organization 20 1.01 Remember structural organization 21 1.01 Remember structural organization 22 1.01 Remember structural organization 23 1.01 Remember structural organization 24 The Skin 1.01 Remember structural organization The Tongue 25 1.01 Remember structural organization 26 1.01 Remember structural organization 27 Male Female 1.01 Remember structural organization 28 1.01 Remember structural organization 29 Anatomical position 1.01 Remember structural organization 30 Anatomical position Discuss the importance of anatomical position. 1.01 Remember structural organization 31 Directional terms 1.01 Remember structural organization 32 Directional terms 1.01 Remember structural organization 33 Directional terms 1.01 Remember structural organization 34 Body planes 1.01 Remember structural organization 35 Body cavities 1.01 Remember structural organization 36 1.01 Remember structural organization 37 1.01 Remember structural organization 38 Group Review Essential Questions How is the human body organized?
