He right and left coronary arteries the right and left coronary arteries supply blood to the pericardial sac drain into the right atrium branch from the aortic arch drain into the coronary sinus supply blood to the heart muscle itself

Superior Vena Cava

main vein; carries/drains deoxygenated blood from head, neck, shoulders into right atrium; located to the right of the aorta

- Two main tributaries that drain into it:

- Right brachiocephalic vein

- Left brachiocephalic vein

Inferior Vena Cava

carries/drains deoxygenated blood from the abdomen into the right atrium; enters the right atrium from the inferior side

Pulmonary Veins

carry oxygenated blood into the left atrium on posterior aspect; only veins that carry

oxygenated blood; four total

supplies blood to the heart itself

-Left Coronary Artery

-Right Coronary Artery

Arteries of the Heart

Left coronary artery

its branches supply:

- Left atrium

- Most of the left ventricle

- Some of the right ventricle

- Interventricular septum

- SA node (40% of people) (sinoatrial node)

protocol for imps extraction focusing on membrane protein extraction, solubilisation, and purification.
