  1. What are the 7 types of connective tissue?
  2. What is active transport and how does it work?
  3. What is the cell nucleus and what is its function?
  4. What are the two main body cavities and what is contained in them?
  5. What is cellular respiration?
  1. a 1. Blood- plasma, RBC, WBC and platelets
    2. Areolar- Subcutaneous. Connects skin to muscles. Mucous membranes
    3. Adipose- Subcutaneous. Sores excess energy in fat. (insulation)
    4. Fibrous- Tendons and ligaments and dermis of skin (strong)
    5. Elastic- Walls of large arteries and alveoli in lungs (promotes normal exhalation and helps maintain blood pressure)
    6. Bone- Support the body, protect internal organs, store calcium and contain and protect red bone marrow
    7. Cartilage- Wall of trachea to keep airway open, on joint surfaces to prevent friction, tips of nose and outer ears. Absorbs shock between vertebrae
  2. b 1. The dorsal cavity which contains the spinal and cranial cavity
    2. The ventral cavity which contains the thoracic, abdominal and pelvic cavities
  3. c name for energy production within cells and involves the respiratory gases: oxygen and carbon dioxide
    (ex: glucose and oxygen combine to make carbon dioxide, water, ATP and heat)
  4. d Nucleus is within the cytoplasm and has a nuclear membrane with nucleoli and chromosomes of the cell. Nucleolus is where DNA and all genetic info for human traits lies.
  5. e requires ATP to move molecules from an area of lesser to an area of greater concentration.
    (Example: sodium pumps to move Na+ out of the cells)

5 Multiple choice questions

  1. A solution with lower salt concentration than in the cells
    (cells burst) MORE WATER THAN IN CELL
  2. Heart and lungs
  3. A solution with a higher salt concentration than in the cells
    (cells shrink) LESS WATER THAN IN CELL
  4. Serous membranes: line some closed body cavities and cover the organs in those cavities (thoracic and abdominal cavities) CAVITIES THAT AREN'T OPEN TO AIR
    Mucous Membranes: line the body tracts that have openings to the environment and have a mucous membrane to keep the lining of the cells wet (vagina, trachea, esophagus and stomach)
  5. covalent bond formed between two atoms of sulfur
    (ex: strand of hair maintains its shape)

5 True/False questions

  1. What are the different kinds of bonding atoms?- cell membrane
    - nucleus
    - cytoplasm and organelles

          

  2. What is a positive feedback mechanism?bodys response to stimuli reverses the stimulus in effect turning it off for a while and keeps the body within normal range

          

  3. Point out cell organelles and name

          

  4. What is contained in the abdominal cavity?liver, stomach and intestines

          

  5. What are the cell organelles and what do they do?ER or endoplasmic reticulum- are tubules that transport materials necessary for cell function within the cell.
    Ribosomes- are very small structures made of protein and ribosomal RNA and are found on the surface of rough ER.
    Proteasome- is a barrel shaped organelle made of enzymes that cut protein molecules apart.
    Golgi apparatus- are flat, membranous sacs where carbohydrates are synthesized and are packed with other materials for cellular secretion.
    Mitochondria- are oval organelles bound by a double membrane where cell respiration takes place and site of ATP production.
    Lysosomes- are single membrane structures that contain digestive enzymes and eat dead cells and bacteria .
    Centrioles- are a pair of rod shaped structures outside the nucleus that spindle fibers during cell division.
    Cilia and Flagella- are thread-like projections through the cell membrane that can sweep materials across cell surface and flagellum provide mobility of the cell.
    Microvilli- are folds of the cell membrane that increase surface area of membrane when needed. They are good for absorption of nutrients as well.
    Cytoskeleton- are the framework and support of the cell. Made of microfiliaments.
