A Scenic Tour of the Heart Welcome to the health science travel agency. Today you will be driving through the heart monitor super highway and taking a trip into the world of the internal heart. Ladies and gentleman start your engines! We have been injected into the jugular vein (have the students point to their neck) and are about to enter the superior vena cava. There will be some turbulence here as we will be experiencing the inflow from the inferior vena cava as we enter the right atrium of the heart. Notice the size of these two vessels, they comprise the largest veins in the human body. Here we move quickly into right atrium, the first of four chambers of the heart. The atria are sometimes called the auricles of the heart because they resemble large flapping ears. Notice the cave like indentations along the heart wall. These are the trabeculae of the heart. Look at how the blood swirls through these tiny indentations to create a whirlpool effect. Look closely at the lining of the heart wall, the endocardium. See how smooth and shiny it is. No blood clots will form here. You may be able to see the fossa ovalis there on the back wall. This is what remains of the fetal circulation where the blood moved from one atrium to another to bypass the lungs. The swirling motion of the blood is getting stronger. Be careful there along the side wall as the coronary sinus empties into the right atrium. We are now ready to drop down through the tricuspid valve. That flash of light overhead must be coming from the sinoatrial node, the pace- maker of the heart. It triggers the impulse for the atria to contract. Here we go... The impulse slows down slightly at the AV node so that the atria can fully contract. Well we made it through there safely. Did you notice the three leaf like cusps that close the chamber between the right atrium and the right ventricle? This is a valve of the heart that only allows for the blood to flow in one direction. Take a good look at those support structures we call chordae tendinae that have been designed to take a lot of stress and still maintain a strong support system. The chordae tendinae help to connect the cusps to the big muscles down there called papillary muscles. When they contract, the valve will close and blood hitting against the closed valve will help to create the lub sound.
The right ventricle is beginning to contract. Hold on tight as we are speeding through the pulmonary semilunar valve and into the pulmonary trunk. Cover your ears as the pulmonary semilunar valve closes. The dub sound is strong as blood hits against the closed semilunar valve. It is narrowing here in the pulmonary arteries we will have two choices, the right or the left in the next few seconds. The swirling blood will funnel us directly into one of the lungs. Here we must miniaturize even further so as not to be a moving clot or pulmonary embolism. Down sizing 3, 2, 1, now. This is a dangerous part of the trip. We are only the size of the red blood cells that are floating near us. Look out!! One just about bumped us through the wall of the alveoli! That would have been a disaster. We need all the power we can muster to stay on our course toward the pulmonary veins. The color of the blood is a brighter red here as we have reoxygenated and are in the arteriole in just a few moments we will be able to increase our size again. Now we are back into the pulmonary veins and traveling towards the heart. Whoosh...we just passed into the left atrium. Is everyone OK? Get ready; the next major passage way could be rough. Hold on to something. Wheeee what a rush! We just passed through the bicuspid or mitral valve. Did you see any signs of deterioration? This is the valve of the heart that tends to weaken and break down. Take a good close look at the myocardium here in the left ventricle. The wall of the heart here is very thick, remember that all the blood in here has to be pumped to the rest of the body. The av bundle has been stimulated and the purkinje fibers are firing. We should be up and on our way through the aortic semilunar valve in just a moment. Here we go... Did you hear the dup sound as the valve closed behind us? Well here we are in the ascending aorta and are about to move into the aortic arch. We will be leaving the heart by way of the left subclavian artery. Watch for it over head. Here comes the brachiocephalic artery, we have passed it successfully. The common carotid is next. Maybe we could take a side trip into the brain. We will do that next time. Well the trip is finally over. We will turn at the next lumen. Hope you enjoyed the ride! Left Subclavian artery here we come!
PUMPS YOUR BLOOD - SONG The Pump Pump Pumps Your Blood song explains how the human heart works - how the heart routes blood through the human body! It was first heard on episode #142 of Happy Days sitcom TV show, "Potsie Quits School" and is known as the Potsie's Pump Your Blood song! Facing the failing of his anatomy class final exam, Potsie (Anson Williams) threatens to quit school. Fonzie tells him to use music (the Pump Your Blood song) as a tool to help him with passing the exam. Lately, the song is again made famous by the St. Joseph Aspirin television commercial as the Pumps Your Blood song. This is a great lesson in how the blood circulatory system works. Can you identify the missing structures that are not part of the song? The numbered dots represents missing Anatomical items. "PUMP YOUR BLOOD" SONG - VERSE ONE Pum- Pum- Pum- Pump, Pum- Pum- Pum- Pump, Pum- Pum- Pum- Pump, Pumps Your Blood! The right atrium s where the process begins, where the CO2 Blood enters the heart. Through the tricuspid valve, to the right ventricle, the pulmonary artery, and lungs. Once inside the lungs, it dumps its carbon dioxide and picks up its oxygen supply. Then it s back to the heart through the pulmonary vein, through the atrium, and left ventricle. Pum- Pum- Pum- Pump, Pum- Pum- Pum- Pump, Pum- Pum- Pum- Pump, Pumps Your Blood! "PUMP YOUR BLOOD" SONG - VERSE TWO The aortic valve s where the Blood leaves the heart, then it's channeled to the rest of the bod. The arteries, arterioles, and capillaries too bring the oxygenated Blood to the cells. The tissues and the cells trade off waste and CO2, which is carried through the venules and the veins Through the larger vena cava to the atrium and lungs, and we're back to where we started in the heart. Pum- Pum- Pum- Pump, Pum- Pum- Pum- Pump, Pum- Pum- Pum- Pump, Pumps Your Blood! Download the Song here: http://www.macjams.com/song/6756 Additional Websites: http://www.stjosephaspirin.com
