Superior vena cava

Right bronchus and right pulmonary artery
Which nerve runs medial to the azygos vein?
Right phrenic which runs into the fibrous pericardium.
Which nerve runs posterior to the phrenic?

The oblique vein, great, middle, and small cardiac veins drain where?

What cardiac veins drain DIRECTLY into the right atrium (not to the coronary sinus)
Coronary sinus

Anterior cardiac veins
The smooth surface in the right atrium formed from what?

The rough surface developed from what?

What is the junction between them?
Smooth - from vena cava

Rough - from heart muscle

Crista terminalis
What is the name of a notable depression inside the right atrium?
oval fossa
How many cusps do the right and left atrium have?
Right - 3 cusps (tricuspid valve)

Left - 2 cusps (mitral valve)
What connects travels from the intraventricular walls to the papillary muscles?
Septomarginal trabecula

This shortens the distance for impulse to run.
The ________ muscles contract and pull on the chordae tendinae, which close the cusps.
