right auricle, increase capacity of atrium

Right atrium purpose?

receives blood from vena cava, flows blood into right ventricle

What is 2? Purpose?

right ventricle, pumps blood into pulmonary artery

What is 3?

left auricle

Left atrium purpose?

receives blood from pulmonary veins, flows blood into left ventricle

What is 4? Purpose?

left ventricle, pumps blood into aorta

joins pulmonary artery and aorta, bypasses lungs

What is the foramen ovale? Purpose?

hole in the wall separating the left and right atrium, bypasses heart and lungs
