  1. Basic Life Properties Obtain/process nutrients Transport nutrients within self Eliminate waste Exchange gases w/ environment Maintain water/ solute balance Possess protective boundary w/ envir. Sense stimulus React to stimulus Reproduce

  2. Smallest (bacteria) Largest (Blue Whale)

  3. Structural Hierarchy of biological order Image from: http://www.cameron.edu/~rong/AnatomyLecture.html

  4. Atom

  5. Molecule

  6. Macro Molecule- DNA

  7. Another DNA model

  8. Organelles & Cells (Eukaryotic & Prokaryotic cells) (Made from many large molecules)

  9. Tissue: similar cells in collaboration (tissue)

  10. Organs: Tissues in collaboration (eg. Stomach/Leaf)

  11. Organ Systems:Organs in collaboration

  12. Organism(of many organ systems) http://trc.ucdavis.edu/biosci10v/bis10v/week10/systems1.gif

  14. Basic Life Properties

  15. Tissue types: • Epithelial • Connective • Nervous • Muscle www.human-anatomy.com

  16. epithelial tissues • Functions: • Absorption • Secretion • Protection • Filtration • Movement of materials • Glandular • Excretion • NO BLOOD

  17. Arrangement: • Simple • Stratified • Pseudo stratified • Cell shape: • Squamous • Cuboidal • Columnar • transitional

  18. Examples of Simple Squamous

  19. Stratified Squamous Epithelium

  20. keratinized stratified squamous epithelium

  21. Figure 40.1x Epithelial tissues

  22. Modifications of Free/Apical surface • Cilia • Microvilli • Cuticle • Mucous membrane

  23. Cilia- on Simple Columnar Epithelium

  24. Microvilli- on Simple Columnar

  25. Cuticle (waxy)-on Squamous epithelium

  26. Cuticle-tooth enamel Tooth

  27. Mucous Membrane(from Goblet cells)

  28. Connective Tissue • Cells embedded/suspended in… • Matrix • Fibers & • Ground substance (Liquid, Semi-solid, solid)

  29. Connective Tissue • Major Functions • Support • Connection • Transport • Storage • Insulation

  30. Vascular Tissue: Blood (below) & Lymph • Liquid matrix = the plasma • Cell types = red blood cells (erythrocytes), white blood cells (leukocytes) & cell fragments called platelets

  31. Vascular Tissue: Lymph (below) • Liquid matrix = lymph fluid • Cell types = white blood cells (leukocytes) & No RBCs (erythrocytes) Photo from http://www.nhs.uk/conditions/Lymphoma/Pages/Introduction.aspx?url=Pages/What-is-it.aspx

  32. Connective Tissue Proper (CTP)
