From the right atrium it goes to the right ventricle- which pushes it to the lungs via pulmonary arteries. When it gets to the lungs it gives off CO2 that you exhale and takes on a new load of oxygen that you inhale, newly oxygenated blood comes out of lungs through pulmonary veins. Enters left atrium, then goes to left ventricle, left ventricle pumps it to all parts of the body by way of the aorta - 22.2 exact location of the heart o More of the heart on your left side of the body than there is on your right side Left lung is a little smaller than the right Cardiac notch in the left lung to allow for that additional part of the heart that’s on the left side of the body o Lungs sit right above the diaphragm, and the heart is attached to the posterior side of the diaphragm o Posterior of the heart is the vertebral column, and on each side of the vertebral column is a portion of each lung - 22.3 structure of the heart wall o endothelium Lumen of the entire cardiovascular system (and also lymphatic system) is

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
