  1. 1.01 Remember structural organization

  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. Organization of the human body:Tissues Types of tissues: • Epithelial tissue • Connective tissue • Muscle tissue • Nervous tissue 1.01 Remember structural organization

  5. Organization of the human body:Tissues Epithelial Tissue protects the body by covering internal and external surfaces, and produces secretions • Skin • covers the outside of the body • Membrane • two thin layers of tissue that join together • cells may secrete a fluid 1.01 Remember structural organization

  6. Organization of the human body:Tissues Epithelial tissues Squamous Cuboidal Columnar 1.01 Remember structural organization

  7. Organization of the human body: Tissues 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

  8. 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

  9. Organization of the human body:Tissues Muscle tissue Cardiac Skeletal Smooth

  10. Organization of the human body:Tissues • Nervous tissue reacts to stimulation and conducts an impulse 1.01 Remember structural organization

  11. Organization of the human body:Tissues Nervous tissue Neuron 1.01 Remember structural organization

  12. Organ Systems 1.01 Remember structural organization

  13. Skeletal System • Bones, cartilage, ligaments • Support • Protection • Movement 1.01 Remember structural organization

  14. Muscular System • Skeletal muscles • Movement • Produce heat • Support • Protection 1.01 Remember structural organization

  15. Circulatory System • Heart, blood vessels, blood!!!!!!!!!!! • Pumps blood • Maintain blood pressure • Transports oxygen Click here to hear heartbeat 1.01 Remember structural organization

  16. Lymphatic System • Lymph vessels, Lymph nodes, Spleen, Thymus • Stimulate the immune response • Filters • Produces lymphocytes 1.01 Remember structural organization

  17. Respiratory System • Nose, Pharynx, Larynx, Trachea, Bronchi, Lungs, Alveoli • Transport and exchange of oxygen and carbon dioxide. 1.01 Remember structural organization

  18. Digestive System • Salivary glands, Pharynx, Esophagus, Stomach, Intestines, Liver, Gallbladder, Pancreas. • Digests food • Absorbs nutrients • Secretes digestive enzymes • Removes waste products 1.01 Remember structural organization

  19. Integumentary System • Skin, Hair follicles, Sweat glands, Nails • Protects • Regulates temperature • Sense of touch 1.01 Remember structural organization

  20. Nervous System • Brain, Spinal cord, Peripheral nerves • Processes information • Controls voluntary activities • Relays information 1.01 Remember structural organization

  21. Sensory System • Eyes, Nose, Skin, Ears, Mouth • Sense of: • sight • hearing • smell • touch • taste The Skin The Tongue 1.01 Remember structural organization

  22. Urinary System • Kidneys, Ureters, Bladder, Urethra • Forms, concentrates and eliminates urine • Regulates chemical composition of the blood 1.01 Remember structural organization

  23. Endocrine System • Pituitary gland, Thyroid gland, Parathyroid gland, Thymus, Adrenal glands, Pancreas, Gonads (testes and ovaries) • Controls all body function • Regulates glucose • Regulates fluid balance • Supports sexual characteristics 1.01 Remember structural organization

  24. Reproductive System • Male: • Testes, Accessory organs, External genitalia • Reproductive processes • Male 1.01 Remember structural organization

  25. Reproductive System • Female: • Ovaries, Uterus, Vagina, External genitalia, Mammary glands • Reproductive Processes Female 1.01 Remember Structural Organization

  26. Structural organization unitshttps://www.youtube.com/watch?v=kvHWnJwBkmo(Just watch. I’ll give you notes next.) 1.01 Remember structural organization

  27. Structural organization units Anatomical position: Body is facing forward, standing erect, feet parallel, holding arms at side with palms facing forward. 1.01 Remember structural organization

  28. Structural organization units Anatomical position Discuss the importance of anatomical position. 1.01 Remember structural organization

  29. Structural organization units Directional terms: refer to location of a structure or the relative position of a body part to another one. Anterior/Ventral: front of the body Posterior/Dorsal: back of body 1.01 Remember structural organization

  30. Structural organization units Directional terms Medial: towards middle LATERAL: towards side 1.01 Remember structural organization

  31. Structural organization units • Directional terms • Superior: refers to head, top or upper body or section • Inferior: refers to tail, bottom or lower body or section • Cranial: refers to the head • Caudal: refers to the tail or tailbone • Directional terms 1.01 Remember structural organization

  32. Structural organization units Directional terms SUPERFICIAL: on or near the surface Deep: on the inside Proximal: refers to nearest to the point of insertion Distal: refers to farthest from the point of insertion

  33. Structural organization units Body planes: an imaginary line that divides the body or an organ into sections Sagittal: divides the body into right and left halves (midsagittal means equal halves) Frontal: divides the body into anterior and posterior sections (also known as coronal plane) TRANSVERSE: divides the body into top and bottom sections 1.01 Remember structural organization

  34. Structural organization units Body Cavity Video • https://www.youtube.com/watch?v=xL4TWO5CC84 (again… just watch)

  35. Structural organization units • Body cavities: spaces within the body that contain and protect organs • Cranial and Spinal = Dorsal • Thoracic, Abdominal and Pelvic =Ventral 1.01 Remember structural organization

  36. Structural organization units • Body Cavities: • DORSAL= • Cranial: contains brain • Spinal: contains spinal cord

  37. Structural organization units • Body Cavities: • VENTRAL= • Thoracic: contains heart, lungs, bronchi, trachea, esophagus, and thymus gland • Abdominal: contains stomach, liver, gallbladder, pancreas, spleen, intestines, and appendix • Pelvic: contains urinary bladder, reproductive organs and rectum • (Abdominopelvic = abdominal + pelvic cavities)

  38. Abdominal Quadrants 1.01 Remember structural organization

  39. Abdominal Regions Middle column- Epigastric: area just below the sternum (breastbone) UMBILICAL: area around the umbilicus (navel) Hypogastric: area below the stomach (pubic area) Side columns- Right and left Hypochondriac: areas below the ribs Right and left Lumbar: area on each side of the umbilicus. Right and left Iliac: areas to the side of the pubic area (also known as the inguinal areas) 1.01 Remember structural organization

  40. 1.01 Remember structural organization Group Review

  41. 1.01 Remember 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
