  1. sinoatirial (SA) node
  2. skeletal muscle
  3. shygomomanometer
  4. open system
  5. route of blood
  1. a contract around vein to push blood up
  2. b bicuspid valve to left ventricle to aortic semi-lunar valve to ascending aorta to aortic arch to descending aorta to lower body cells to capillaries to gas exchange to inferior vena cava to right atrium to tricuspid valve to right ventricle to pulmonary valve to pulmonary artery to lungs to gas exchange to pulmonary veins to left atrium to bicuspid valve
  3. c the pacemaker: specialized group of muscle cells in right atrium
    - initiates its own impulses to for the heart to contract
  4. d instrument that measures blood pressure
  5. e -blood is not always contained in tubes
    -open ended vessels
    -fluid directly bathes cells

    - diffusion and active transport brings materials in
  2. - carries blood away from heart
    - majority carries oxygenated blood to body cells
    - smooth muscle causes to be thicker
    - only aortic and pulmonary arteries have valves
  3. - dorsal vessel is along the back
    - 5 aortic arches
    - ventricular vessel is close to ground
    - blood carries nutrients, gases, waste
    -contains hemoglobin (which carries more oxygen)
  4. carried blood between the heart and the lungs
  5. 1. pacemaker generates electrical impulses
    2. impulses spread through the atria
    3. impulses reach the ventricles

5 True/False questions

  1. septumsomething to force fluid throughout the organism


  2. fluidwhat materials are transported or dissolved in


  3. venule- small veins
    - carries deoxygenated blood to the heart


  4. diastolic pressurethe pressure during ventricular systole


  5. hepatic-portal- nutrients are picked up by capillaries in stomach and small intestine and transported to the liver
    - liver detox blood
    - excess nutrients is stored in liver
