  1. A&P Chapter 3: Cells

  2. Warm Up 9/12/13 • Which transport processes are used in each of the following situations? • Breathing in oxygen and exhaling carbon dioxide • Blood pressure forces small molecules out of capillaries • Proteins pump sodium ions out of the cell to maintain membrane potential • Insulin promotes absorption of glucose into cells after eating cake • A white blood cell engulfs bacteria and cellular debris • HIV transports itself across the epithelium lining of certain reproductive organs • Water moves through pores in cell membrane from an area of high concentration to low concentration

  3. Objectives • Describe the general characteristics of a composite cell and the basic functions of its organelles • Explain how the components of a cell’s membrane provide its functions • Explain how substances move in and out of cells • Explain how stem cells and progenitor cells make possible growth and repair of tissues
