Journey of a red blood cell to the heart?

Yep. Starting in the hand, the rbc travels through veins in the hand to the brachial vein in the arm, then the subclavian vein and then the superior vena cava which merges with the inferior vena cava. From there, our rbc enters the right atrium of the heart. Our rbc is then pumped to the right ventricle, and from there out through one of the pulmonary arteries to one of the lungs, where the arteries narrow to arterioles and then to capillaries, which pass alongside alveoli of the lungs. In the arterial end, our rbc gives up its CO2 by diffusion into the alveolus and at the venule end, it picks up O2 from the alveolus which binds to hemoglobin on the rbc. The pulmonary system is the only place where arteries carry deoxygenated blood and veins carry oxygenated blood. Our rbc then enters a pulmonary venule, then one of the pulmonary veins (left or right, depending on which lung it went to), where it enters the left atrium. From there, it is sent to the left ventricle and out of the heart to the ascending aorta, which branches to form the subclavian artery and then the brachial artery, branching into smaller arteries and ttravelingto the hand, where the small arteries branch into arterioles and then narrow to capillaries. Our rbc enters one of these capillaries where it gives up O2 to the tissues of the hand and takes up CO2 . It then enters a venule, which will open into a vein in the hand, which will enter the brachial vein, the subclavian vein and the superior vena cava, combining with the inferior vena cava to enter the right atrium again. End of round trip!

n order to talk about the journey of red blood cells with reference to the lungs you need to take in consideration the right side of the heart first. Deoxygenated blood flows through your right atrium from the veins connected to the right atrium. As your right atrium contracts it pushes the deoxygenated blood into the right ventricle. As the deoxygenated blood follows through the right ventricle it gets pushed to the pulmonary vein. As the deoxygenated blood moves through the pulmonary vein it goes to the capillaries of the lungs. Here in the capillaries the blood uptakes oxygen and gets rid of carbon dioxide. After this has occured, the newly oxygenated blood moves from the capillaries in the lungs to the pulmonary artery. The pulmonary artery pushes the oxygenated blood to the left atrium of the heart. When the left atrium contracts, it pushes the oxygenated blood to the left ventricle. When the left ventricle contracts it pushes the oxygenated blood to the aorta where it finally leaves the heart and goes out through a series of arteries.

1) the deoxygenated red blood cell travels back to the heart in the vena cava 2) it enters the right atrium 3) the right atrium contracts and pushes it through the tricuspid and into the right ventricle, 4) the right ventricle contracts and pushes it out of the heart through the semi lunar, 5) it travels through the pulmonary artery to the lungs, 6) here it picks up oxygen, 7) it travels back to the heart through the pulmonary vein, 8) it enters the left atrium, 9) the left atrium contracts and pushes it through the bicuspid and into the left ventricle, 10) the left ventricle contracts and pushes it through the semi lunar out of the heart and into the Aorta. 11) They travel through the Aorta and into the kidneys, trunk and lower limbs. 12) Then the de-oxygenated blood travels up through the Vena Cava and then it starts again.

This Site Might Help You. RE: Journey of a red blood cell to the heart? Okay so our task in science at school is to write an essay, draw a series of cartoons about a red blood cell and it's journey from the start to the hand or lungs, in going to do the hand. Can someone please tell me the FULL journey or cycle of the red blood cell to the hand or lung :)
