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

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

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

20. Examples of Simple Squamous

21. Stratified Squamous Epithelium

23. keratinized stratified squamous epithelium

24. Figure 40.1x Epithelial tissues

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

26. Cilia- on Simple Columnar Epithelium

27. Microvilli- on Simple Columnar

28. Cuticle (waxy)-on Squamous epithelium

29. Cuticle-tooth enamel Tooth

30. Mucous Membrane(from Goblet cells)

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

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

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

34. 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
