  1. What is diffusion and how does it work?
  2. What are the cell organelles and what do they do?
  3. What are the serous membranes and where they are located?
  4. What areas do connective tissue membranes cover?
  5. Describe an ionic bond?
  1. a movement of molecules from an area of greater concentration to an area of lesser concentration along the concentration gradient. Very slow process. FOR MOLECULES
    (Example: exchange of gases in lungs or body tissues)
  2. b 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.
  3. c meninges line the cranial and spinal cavities and cover the brain and spinal cord. They "line" and "cover".
  4. d Serous membranes are in closed body cavities where the serous fluid prevents friction between the two layers of the serous membrane.
    ---Thoracic cavity: partial pleura lines chest wall and cisceral pleura covers the lungs.
    ---Pericardial sac: parietal pericardium lines the fibrous pericardium and the visceral pericardium covers the heart muscle.
    ---Abdominal cavity: peritoneum lines the abdominal cavity and mesentary covers the abdominal organs
  5. e Involves loss of electron of one atom and the gaining of an electron on another atom (ex: NaCl or salt)

5 Multiple Choice Questions

  1. 1. The dorsal cavity which contains the spinal and cranial cavity
    2. The ventral cavity which contains the thoracic, abdominal and pelvic cavities
  2. 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)
  3. C6H12O6
  4. 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. Line the body tracts open to the environment
    ---respiratory , digestive, urinary and reproductive
    ---mucus keeps the living epithelium we and provides lubrication in the digestive tract
    ---traps dust and bacteria in the respiratory tract

5 True/False Questions

  1. What is contained in the spinal cavity?Contains skull and brain (CNS)

          

  2. Review the types of cells by shape

          

  3. What are the 7 types of connective tissue?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

          

  4. Describe a chemical bond?Covalent bonds share electrons between atoms
    (ex: H20 or water)

          

  5. What is mitosis?process of cell division that results in the formation of gametes which are egg and sperm cells.
    (used for creating human life)
