Q

Where does the right coronary artery travel?

A
  • Sinoatrial nodal artery is first branch to SA
  • Second is typically a conus branch
  • Third is the atrial branch
  • Almost always right marginal
  • Travels to diaphragmatic surface of heart to produce:
    • Posterior interventricular artery (largest)
    • Right posterolateral artery
    • AV nodal artery

  • Anterior interventricular artery (LAD)
    • Conus branch
    • Lateral artery
    • Interventricualr septal branches

Q

What is a coronary artery bypass graft?

A
  • Done when the coronary artery is obstructed and needing replacement
  • Great saphenous vein is used as it is comparable diameter to coronary arteries and easily dissected from the leg
  • Can also use radial artery

Q

What is a coronary angioplasty?

A
  • insertion of a small balloon catheter into lumen of coronary artery
  • Inflation of the catheter flattens the obstructing plaque against wall and increases the size of lumen

Q

Right pulmonary artery branches?

A
  • superior lobar artery to superior lobe
  • Middle lobar
  • Inferior lobar
18
Q

What is the characteristic of the blood being carried by the pulmonary arteries?

A

Deoxygenated, it is coming from the (systemic circulation) right ventricle to pick up oxygen

19
Q

What is a pulmonary embolism?

A
  • Obstruction of pulmonary artery by an embolus such as blood clot, globule, or air bubble
  • It usually travels from a vein through the right side of heart into pulmonary artery
20
Q

What do pulmonary veins do and describe the location?

A
  • Empty into left atrium
  • 2 on right 2 on left
  • 2 are superior and 2 are inferior
21
Q

What vein empties into the right atrium directly?

A
  • Anterior cardiac vein
22
Q

Where does the great cardiac vein originate and travel to?

A
  • Originates on anterior part of heart btw right and left vents
  • Travels with anterior interventricular artery
23
Q

Where does middle cardiac vein travel and sit?

A
  • Travels posterior aspect of heart btw right and left vent
  • Travels with Posterior interventricular artery
  • Drains into coronary sinus which drains into right atrium
24
Q

Where does small cardiac vein travel and drain?

A
  • travels along inferior border of heart, rarely seen
  • Travels with right marginal artery
  • Drains into coronary sinus
25
Q

What is function of azygos vein?

A
  • Drains the right side posterior intercostal veins and drains into SVC
  • right side has single azygos vein
26
Q

Where does the thoracic duct originate from?

A
  • Chyle cistern in the abdomen
  • No branches in the thoracic cavity
27
Q

Where do axillary lymph nodes drain?

A
  • subclavian lymphatic trunk into the right lymph duct or thoracic duct
