Splenic + SMV
Which main bronchus is more vertical and therefore more directly aligned with the trachea?
Right main bronchus
Which structure separates the right and left atrial appendages externally?
Interatrial groove
Which part of the cardiac skeleton forms the structural boundary around the atrioventricular openings?
Fibrous annuli
Which artery becomes the axillary artery after crossing the lateral border of the first rib?
Subclavian artery
Which superficial vein ascends along the medial side of the lower limb and drains into the femoral vein?
Great saphenous vein
Which lung contains two lobes but has a cardiac notch and lingula?
Left lung
Which chamber forms most of the diaphragmatic surface of the heart?
Left ventricle
Which fibrous structure lies between the aortic and mitral valve complexes?
Aortic–mitral curtain
An artery passes through the axillary region, continues into the arm, and terminates by dividing near the cubital fossa. Identify the complete arterial sequence.
xillary → brachial → radial + ulnar
A vein ascends through the posterior thorax, crosses toward the superior vena cava, and provides a connection between caval systems. Identify it.
Azygos vein
At the lung root, the pulmonary artery lies anterior to the bronchus on one side and superior to it on the other. State the relationship on each side.
Right: anterior; Left: superior
