  1. Name some ways the body uses homeostasis?
  2. What is the anatomical position of the body?
  3. What are the 7 types of connective tissue?
  4. What are the two main body cavities and what is contained in them?
  5. What is hypotonic?
  1. a 1. The dorsal cavity which contains the spinal and cranial cavity
    2. The ventral cavity which contains the thoracic, abdominal and pelvic cavities
  2. b Positive and negative feedback mechanisms
  3. c 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. d A solution with lower salt concentration than in the cells
    (cells burst) MORE WATER THAN IN CELL
  5. e Standing with legs shoulder width apart, arms down by side with palms forward

5 Multiple Choice Questions

  1. Requires energy of mechanical pressure. Water and dissolved materials are FORCED through a membrane from an area of higher PRESSURE to an area of lower PRESSURE
    (Example: formation of tissue fluid and the first step in the formation of urine)
  2. 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.
  3. 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
  4. 1. Epithelial membranes
    2. Connective Tissue membranes
  5. the response to stimuli does not stop but rather keeps the sequence of events going. (requires an external brake)
    EX: cervical stretching during childbirth

5 True/False Questions

  1. What are the two types of epithelial membranes?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)

          

  2. What is facilitated diffusion and how does it work?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)

          

  3. What is hypertonic?A solution with a higher salt concentration than in the cells
    (cells shrink) LESS WATER THAN IN CELL

          

  4. Where is genetic coding found?In the DNA of our chromosomes or our genome. It is found in the cell nucleus.

          

  5. What is contained in the cranial cavity?Spinal vertebre
