  1. Biological Building Blocks of Life Cell Diversity Tissue Diversity Classification of Body Membranes

  2. Biological Building Blocks of Life Cell Diversity Tissue Diversity Classification of Body Membranes

  3. Cell Diversity Anatomy: The study of the parts (eg. cells, tissues, organs, systems) of an organism Physiology: The study of the functions of the parts of an organism • An average human body are made up of 200+ different cell types • These vary greatly in size, shape and function • All are derived from one single cell type: stem cell For simplicity, we will categorize these cells base on their functions

  4. b) cover and line body organs Cells that … epithelial cells a) connect body part c) move organs and body parts muscle cells fibroblasts erythrocytes d) store nutrients e) fight disease fat cells macrophage f) gather info & control body functions g) involve in reproduction sperm nerve cells

  5. General Cell Shapes

  6. Cell combinations Esophagus lining Bladder lining

  7. Tissue Diversity • Tissues are made up of ________ ________ • There are four (4) different types of tissue nervous muscle epithelia connective bone blood loose connective cartilage

  8. Classification of Epithelial Membrane • Epithelial membrane is a covering organ for many organs • There are four (4) different types of epithelial membrane • we will only discuss two (2) of them Mucous membrane Cutaneous membrane (skin)

  9. Cutaneous Membrane • Protect us from: •  germs and cold •  drying out of body’s vital fluid •  mechanical injuries of our soft tissues • Regulate body’s temperature : •  evaporate perspiration •  contract or relax the superficial blood vessels • Act as organ of sense: it has nerve endings • Act as biological gate: it can absorb and eliminate certain substances • Has the fastest renewal rate!

  10. Mucous Membrane • covers body cavities that • open to the outside • epithelia consist of: • stratified squamous • simple columnar cells • is wet because of continuous • exposure to secretions • not all mucosae secrete mucus • (eg. cells that line the urinary tract)
