5 Matching questions

  1. What are the 6 types of epithelial tissue?
  2. What is the cell nucleus and what is its function?
  3. Describe a covalent bond?
  4. What is osmosis and how does it work?
  5. What is a negative feedback mechanism?
  1. a 1. Simple squamous -one layer of flat cells (alveoli of lungs, permits diffusion of gases)
    2. Stratified squamous- many layers of cells (epidermis, lining of esophagus and vagina)
    3. Transitional- many layers of cells (lining of bladder, permits expansion)
    4. Cuboidal- one layer of cube shaped cells (thyroid gland, salivary gland, kidney tubules) excretory
    5. Columnar- One layer of column shaped cells (lining of stomach, lining of small intestine and absorbs products in digestion)
    6. Ciliated- one lay of columnar cells with cilia on free surfaces (lining of trachea to sweep mucus and dust pharynx and lining of fallopian tube to sweep ovum toward uterus)
  2. b 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. c Covalent bonds share electrons between atoms
    (ex: H20 or water)
  4. d bodys response to stimuli reverses the stimulus in effect turning it off for a while and keeps the body within normal range
  5. e diffusion of water through a selectively permeable membrane. water will move from an area with more present to an area with less water present. takes place in the kidneys which reabsorb large amounts of water. FOR WATER

5 Multiple choice questions

  1. 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. Contains skull and brain (CNS)
  3. 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)
  4. 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
  5. A solution with the same salt concentration as in cells

5 True/False questions

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

          

  2. What is an enzyme and what does it do?secretion of an endocrine gland that has effects on target organs
    (ex: Insulin - enables cells to take in glucose and lowers glucose levels. Growth hormone - increases protein synthesis and cell division)

          

  3. What is a hormone and what does it do?secretion of an endocrine gland that has effects on target organs
    (ex: Insulin - enables cells to take in glucose and lowers glucose levels. Growth hormone - increases protein synthesis and cell division)

          

  4. Describe an ionic bond?Force or attraction between positive and negative charges that keeps atoms closely together

          

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