  Capillaries
• A perforating vein connects which of the following

  Superficial to deep vein
• Which of the following has a thicker tunica media

  Arteries
• In adults, where would you most likely find mixed blood

  Capillaries
• Oxygen attaches directly to


  Fe
• Which of the following contains pores

  Fenestrated capillaries
• Blood regulates which of the following

  all of them

  maintain normal pH in tissue

  maintain body temperature

  maintain circulatory fluid volume
• Interstitial fluid enters tissue due to arterial pressure

  False
• Which of the following drains interstitial fluid into the left subclavian vein

  Thoracic duct
• Lacteals are lymphatic capillaries located in


  Within the villi of the small intestine
• Which of the following is true of lymph nodes

  All of them

  Remove cellular debris

  Contain immune cells that fight pathogens

  Filter lymph fluid
• In which of the following do the mesenteric lymph nodes empty

  Cisterna chyli
• Peyer's patches are located

  Submucosa of small intestine
• Sinusoidal capillaries are located

  All of them

  Spleen

  Bone Marrow

  Liver
• Gas exchange occurs in which of the following capillaries

  fenestrated
• Which of the following fluid exits tissue

  Lymphatic
• How many major tracts of the respiratory system?

  2 Major tracts
• What is the upper respiratory tract composed of?

  Paranasal sinuses, nose, pharynx, larynx, minor parts- oral cavity, tongue, esophagus, vocal cords
• What is the lower respiratory tract composed of?

  Trachea, main bronchi, lungs, lobar bronchus, lingular division bronchi
• What is bronchi?

  Two cartilage-ringed tubes near the center of the chest. This section of the respiratory system is lined with ciliated cells.
• How do bronchial tubes form?

  When bronchi enter the lungs and spread in a treelike fashion into smaller tubes
• How do bronchioles form?

  Bronchial tubes divide and further subdivide, and their walls become thinner and have progressively less cartilage that eventually become a tiny group of tubes
• Gases can ___ and ___ between the lungs and the circulatory system

  dissolve and diffuse
• Oxygen diffuses alveolus into


  Capillaries
• Once in the capillaries

  5% of the oxygen will be dissolved in the blood plasma

  95% of the oxygen will bind to hemoglobin in red blood cells
• Surfactant helps to ___ in the airways and this helps ___.

  lower surface tension, keep the lung alveoli open.
• Surface tension

  This tension is determined by the thin liquid film that lines the outside of each alveolus

  This film allows the alveolus to resist expansion also squeezes the alveolus producing recoil

  A coating of pulmonary surfactant prevents the alveoli from collapsing from this surface tension

  Insufficient pulmonary surfactant can produce newborn respiratory distress syndrome.
