Ascending Aorta

The ascending aorta is the initial section of the aorta emerging from the heart, which ascends upwards before curving into the aortic arch.

Left Atrium

The left atrium is the top left section of the heart, responsible for collecting oxygen-rich blood from the lungs via the pulmonary veins and transferring it to the left ventricle.
