Trace a drop of blood from the left knee to the right arm
A red blood cell in the lungs returns to the heart via the pulmonary vein. It enters the left atrium, is pumped into the left ventricle, and then leaves the heart via the aorta.

Red blood cells transport oxygen from the lungs to the tissues and remove carbon dioxide from the tissues back to the lungs for exhalation.
Red blood cells are primarily involved in gas transport, specifically oxygen from the lungs to the tissues of the body.

I LOVE BOOBIES AND SUCK MY BALLS ..l..
The Aorta is the main artery coming out of the heart's left ventricle and allows blood to travel to all the body tissues except the lungs.
gas exchange occurs in the alveoli in the lungs where deoxygenated blood gets oxygen, that blood then goes to the heart and is pumped through the body through the aorta and the arteries, which brings oxygen to the body cells.
Oxygen enters the body by travelling into the lungs, it then diffuses through the alveoli cell wall into the body's biggest artery, the aorta.
Capillaries
The oxygen molecule will enter the capillary. It will get attached to haemoglobin molecule of the red blood cell. The blood (and the red blood cell) will be carried to left atrium via the pulmonary vein. From there the blood will go to to left ventricle. From there it will be carried to ascending aorta, arch of aorta and descending aorta. Then it will go to abdominal aorta. Then it will go to common iliac artery. Then it will go to common iliac artery. Then it will go to external iliac artery. Then it will go to femoral artery. Then it will go to posterior tibial artery. Then from the proximal end of the capillary there, it will enter the interstitial compartment. From there it will go to the muscle cell.
red blood cell is your answer thank you for asking
Red blood cells, corpuscles, transport oxygenated blood from the lungs to the body, and carbon dioxide from the body to the lungs.
As opposed to the left aorta, or as opposed to the wrong aorta?There's only one aorta, so I'm not quite sure what your question is supposed to mean, but yes, blood does flow through the aorta.(Might you, perchance, have meant "atrium" instead? There are a left and right one of those, with the right one being the collector of blood from the superior and inferior vena cava and the left one being the collector of blood from the pulmonary vein.)
Red Blood Cells
The lungs could be gray or have black spots.
The job of a blood cell is to pick up oxygen from the lungs and carrying oxygen to the other cells in the body.
