BLOOD FLOW THROUGH THE HEART HOW TO

Backward prolapse of the cusps is prevented by the chordae tendineaeвЂ“also known as the heart stringsвЂ“fibrous cords that connect the papillary muscles of the ventricular wall to the atrioventricular valves. The cusps are pushed open to allow blood flow in one direction, and then closed to seal the orifices and prevent the backflow of blood. Left coronary artery (circumflex branch, anterior interventricular branch)Д¬oronary sinus (great, middle and small cardiac veins, left marginal vein, left posterior ventricular veins) Right coronary artery (sinuatrial nodal branch, right marginal branch, atrioventricularВ nodal branch, posterior interventricular branch) Tricuspid, pulmonary, mitral, aorticВ valves Pulmonary veins (-> left atrium), superior and inferior vena cavae (-> right atrium), aorta (left ventricle ->), pulmonary artery (right ventricle ->) Sternocostal (right ventricle), diaphragmatic (mostly right ventricle, portion of left ventricle), pulmonary (cardiac impression) surfacesДЄtria (left and right), ventricles (left and right) Superior (atria, auricles), inferior (right and left ventricles), left (left auricle, left ventricle), right (right atrium) borders This page will introduce you to the anatomy of the heart. For instance, you can live without your spleen or with only one kidney, you can even regrow your liverвЂ“but you cannot live without a heart. The heart holds a special position in anatomical sciences. The great vessels that originate from the heart, radiate their branches to the head and neck, the thorax and abdomen and the upper and lower limbs.

The heart is shaped as a quadrangular pyramid, and orientated as if the pyramid has fallen onto one of its sides so that its base faces the posterior thoracic wall, and its apex is pointed toward the anterior thoracic wall. It is found in the middle mediastinum, wrapped in a two-layered serous sac called the pericardium. Now test your knowledge on the blood flow of the heart by taking this quiz.The heart is a muscular organ that pumps blood around the body by circulating it through the circulatory/vascular system. Try to remember that A is before V in the alphabet so atriums (which starts with the letter A) is above the ventricles (which starts with the letter V). By remembering this phrase, you will remember that the tricuspid (try) is before the bicuspid (buy)В valve.ДЄlso, donвЂ™t left the atriums and ventricles mess you up either. Remember this saying, вЂњFirst always try, before you buyвЂќ. Many people get confused on if the blood enters the tricuspid or bicuspid valve first. Lastly up through the AORTA, where it pumped throughout the body Then blood is squeezed into the LEFT VENTRICLEДЎ2. Down through the BICUSPID VALVE (also called mitral valve)ДЎ0. Blood enters from the lungs through the PULMONARY VEINДЁ. Goal: to get the richly, oxygenated blood that LEFT the lungs to the body to feed the brain, tissue, muscles, organs etc.)Д§.

Remember in medical terminology pulmon means lungs.В This will help you keep from getting confused with the left side of the heart. Study Tip: Since the goal of the right side is to get bloodВ to the lungs always remember that the pulmonic valve and pulmonary artery will be on the right side since it is associated with the lungs. Blood is then shot up through the PULMONARY ARTERY and then enters into the lungs for some oxygen Then it is squeezed into the PULMONIC VALVEД¦. Blood then enters into the RIGHT VENTRICLEДҐ. Then it is squeezed through the TRICUSPID VALVEД¤. The un-oxygenated blood (this is blood that has been вЂњused upвЂќ by your body and needs to be resupplied with oxygen) enters the heart through the SUPERIOR AND INFERIOR VENA CAVA.ДЈ. Goal: to get the blood RIGHTto the lungs so it can become oxygenated.ДЎ. StudyВ Tip: When you are having to memorize this for a test, think of the blood flow like this: There are 12 steps, 6 for the right and 6 for the left. The right side is in blue and the left side is in red. For better illustration, look at the picture below and note how the right and left side are separated. Always remember that it must flow through 6 areas on the right side and then 6 areas on the left side (this equals 12 steps). Learn Heart Blood Flow in LESS than 4 Minutes!!Д«lood flows through the heart in 12 easy steps. I found that learning the blood flow of the heart is best done by actually visualizing how the heart is set-up and how it flows through the muscle to the body.ДЄfter reviewing these notes, donвЂ™t forget to take the heart blood flow quiz.
