    left internal jugular and subclavian veins
  2. ___________ ___________excess connective tissue fluid (lymph is the fluid that is formed when interstital fluid enters the initial lymphatic vessels of the lymphatic system)
    lymph fluid
  3. the main thoracic lymphatic duct empties into the venous system
    near the union of the ________ ________ jugular and the ____________
    vein
    left internal jugular and subclavian veins
  4. _________ lymph drains right side of head and neck and right upper limb. ___________ duct drains remainder of body.
    right thoracic
  5. The _____________ lymph node is the first lymph node to which cancer is likely to spread from the primary tumor. Cancer cells may appear in the __________ node before spreading to other lymph nodes. In some cases, there can be more than one ________ lymph node.
    sentinel
  6. Breast Tissue extends into the __________
    (Axillary Tail)
  7. what is the significance in breast cancer of the sentineal lymph node?
    • Hypothetical first lymph node or group of nodes reached by metastasizing cancer cells from a primary tumor.
    • Because lymph axillary tail goes into the axilla area and can become cancerous as well.
  8. why does a self-check breast exam include the axilla?
    sentinel lymph node is a cancer hot spot a self check includes the axilla due to the axillary tail of the mammary gland.
  9. the mammary gland is classified as a _________ ________ gland?
    modified sweat
  10. identify subdivisions of bronchial tree?
    left and right main bronchisdivides into ________ bronchi (2L 3R)-divides into ___________ bronchi-divides into ___________ broncholes which supply the bronchopulmonary segment-divides into ___________ bronchioles-divides into __________ _____________

    • terminal
    • respiratory
    • aveoli sacs
  12. _________ _________ is where is the primary gas exchange in the lungs takes place
    alveolar sacs
  13. _______________ is used to assess air flow through the tracheobronchial tree into the _________ with a stethescope. it is used clinically to listen to patients ______ breath sounds if healthy there will be no sound
    • auscultation,
    • lung
    • bilateral
  14. ________ lung:superior lobe, middle lobe, inferior lobe
    right
  15. _______ lung: superior lobe, inferior lobe
    left
  16. what is the clinical significance of the apex of the lung?
    cupula

    • ductus
    • ligamentum
  18. what are the three structural layers of the heart?
    epicardium, myocardium, endocardium
  19. conduction system of the heart:______________ node-stimulus originates in the SA node and travels across the walls of the atria causing them to contract. initiates and regulates heartbeat (the pacemaker of the heart)
    Sinoatrial
  20. ______________ Node-distributes the SA node signal to the ventricles through __________ bundle. Stimulus descends to the apex of the heart through the bundle branches. After stimulus reaches the Purjinkie fibers, ther ventricles contract path of blood through the heart
    Atrioventricular
  21. _____________ node is a group of cells positioned on the wall of the right atrium, near the entrance of the superior vena cava.
  22. The ___________ _________ node is an area of specialized tissue between the atria and the ventricles of the heart, specifically in the posteroinferior region of the interatrial septum near the opening of the coronary sinus, which conducts the normal electrical impulse from the atria to the ventricles. The AV node is quite compact (~1 x 3 x 5 mm).[2] It is located at the center of Koch's Triangle—a triangle enclosed by the septal leaflet of the tricuspid valve, the coronary sinus, and the membraneous part of the interatrial septum.
