  4. Mg
  5. Nucleus
    Responsible for the cell's Metabolism, Growth, and Reproduction (MGR)

    contains chromosomes and controls every organ
  6. genome
    complete set of genes and chromosomes
  7. stem cells
    precursors of all body cells.

    Qualities: Capable of Dividing and Renewing & are Unspecialized (RUnCD)
  8. Cells
    basic building block of human body
  9. Lysosomes
    'digestive bags'
  10. Ribosomes
    "protein factories"
  11. Golgi apparatus
    "chemical processing and packaging center"

    chemically processes molecules/packages into vesicles
  12. Mitochondria
    "Power Plant"

    cellular metabolism and respiration
  13. Centrioles
    important to cell reproduction
  14. Tissue
    A group of similar cells that together perform specialized functions.  Four main types.
  15. Four types of tissue
    Connective, Muscle, Epithelial, Nerve (CoMEN)
  16. Epithelial tissue
    sheetlike, forms outer surfaces of body, lines body cavities, tubes and passageways that lead to exterior. 

    Cells form secreting portions of glands

    6 Main functions
  17. Six main functions of Epithelial tissue
    • PSADE'S epithelial is sheet like and lines her cavities
    • 1. Protections
    • 3. Secretion
    • 4. Absorption
    • 5. Diffusion
    • 6. Excretion
    • 2. Sensation
  18. 3 types of connective tissue

    • 1. Skeletal - voluntary
    • 2. Cardiac
    • 3. Smooth - involuntary
  19. Connective tissue
    forms supporting network of the body: organs, muscles, cartiladge
  20. Nerve tissue
    consists of neurons (nerve cells) and neuroglia (supporting cells).

    Used to control and coordinate body activity via conductivity
  21. system
    a group of different organs functioning together for a common purpose
  22. Integumentary function
    protective membrane, temp regulator, and sensory receptor
  23. skeletal function
    framework and movement, storage for minerals
  24. muscular system function
    framework and movement, maintains posture and produces heat
  25. nervous system
    communication and control; transmits impulses and responds to change
  26. endocrine system
    communication and control; produces hormones and chemical messengers
  27. cardiovascular system function
    transportation and immunity; transports O2 and CO2, delivers nutrients, removes waste
  28. blood and lymphatic system function
    transportation and immunity; transports O2 and CO2, contains chemical substances and cells that protect against foreign substances
  29. respiratory function
    distribution and elimination; furnishes O2 and removes CO2
  30. Digestive system function
    Distribution and elimination; digestion, absorption, and elimination
  31. Urinary System
    Distribution and elimination; produces and removes urine; maintains electrolytes, water, and acid-base balance
  32. Reproductive System
    cycle of life; responsible for sexual characteristics
