Document Summary
8/30/17: the cell: the most basic structural and functional unit of life. Cytology -- the study of cells : why study cells, cells are little factories which can, 1. Expel waste (to keep themselves alive, like humans): 3. Synthesize large molecules with complex functions: 4. Generate, store, and use energy for metabolic processes: 5. Move: diseases begin at the cellular level, you are made of ~75 trillion cells, 1. Over 200 different types of cells ( structure follows function : 2. Sex (germ/gametes) cell -- sperm / egg: b. somatic cells (soma- ; body) -- cells of the body, cells live in extracellular fluid and is found on the outside of the cell. In the extracellular fluid there will be: waste products, hormones, glucose, oxygen, carbon dioxide, nutrients. Intracellular fluid will be found on the inside of the cell: extracellular fluid = the cellular freeway , 1. Usually a watery fluid (aka interstitial fluid: 2.
