    atrium and the right ventricle. The valve only permits the blood to flow from the atrium to the ventricle (Healthline). The pulmonary valve is at the opening from the right ventricle in the pulmonary artery trunk. “The pulmonary valve moves the blood towards the lungs and keeps it from going back into the pulmonary artery” (Healthline). The mitral valve is between the left atrium and the left ventricle. This valve consents the blood to drift from the left atrium to the left ventricle. The mitral…

  • Heart Failure Research Paper

    the heart muscle has become too stiff. This process mainly relates to the heart muscles of the ventricle chambers. The ventricles are the main problem within heart failure, they are either too stiff or not contracting properly. The heart ventricles cannot pump hard enough during systole, which is called systolic heart failure. Diastolic heart failure is when not enough blood fills into the ventricles during…

  • Systolic Heart Failure Case Study

    mechanical and the neurohumoral issues seen with systolic ventricular dysfunction, one can see how each system and mechanism feeds the other. Hypertension from an unhealthy life style can cause a small amount of damage to the left ventricle. The repair of that ventricle could cause a small amount of ventricular remodeling, which could be just enough to perpetuate a series of events to send the patient into heart…

    atria and ventricles. Between the right atrium and right ventricle, the tricuspid valves exist; and the mitral valve separates the left atrium and left ventricle. Chordae Tendineae, which are attached to the AV valves and anchored to the papillary muscles, allow one-way flow by preventing eversion of the valves. Semilunar valves separate the ventricles from the arterial system. The aortic valve separates the left ventricle from the aorta while the pulmonary valve divides the right ventricle and…

  • Red Blood Cell Case Study

    trace the path of a red blood cell through all anatomical/structural areas of the heart. The path of a RBC consist of it first beginning in the heart as the RBC transports oxygen into the aorta by the aortic valve through contracting of the left ventricle. From the aorta, the RBC then travels through an artery with the help of arterioles to reach the capillaries. When in the capillary, the oxygen molecule that is carried by the RBC then detaches and travels through the capillary into the tissues…

    right atrium, right ventricle, left atrium and left ventricle. The right and left atriums are separated by the interatrial septum and the interventricular septum divides the right and left ventricles. There are atrial-ventricular junctions that differentiate between the atriums and ventricles which contains atrioventricular valves. These valves, known as the tricuspid valve on the right side and mitral valve on the left side, are present to prevent backflow from the ventricles into the atrium.…

    into the body. The blood vessel, vein, has the duty to deliver deoxygenated blood to the heart. The deoxygenated blood pass into the heart from the right atrium with the help of diastole then the deoxygenated blood goes to the right ventricle and the right ventricle has the duty to deliver the deoxygenated blood to the lungs through pulmonary artery and the with the help atria’s…

  • Heart Transplantation Analysis

    It can either serve to provide an extra ventricle or act as a substitute for the entire heart. Dependent on the model, it may have several valves, a mechanism to propel the blood forward, and one or more chambers. The device is made from a combination of metals and plastics, and is fitted with a…

  • Heart Conduction System Essay

    and push blood into the ventricles. Step 2: AV Node Impulse Conduction. From the atria, the electrical signal spreads to the AV node, a group of cells found between the atria. Step 3: AV Bundle Impulse Conduction. The electrical impulse then travels through the AV bundle of His, which divides into a right and left bundle branches. Step 4: Purkinje Fibers Impulse Conduction Then the action potential spreads through the Purkinje fibers, which causes the left and right ventricles to contract. The…

  • Intrinsic Conduction System: A Case Study

    Identify or trace the path of a red blood cell through all anatomical/structural areas of the heart. • The red blood cell carrying oxygen is pushed into the aorta through the aortic valve by contraction of the left ventricle (Marieb, Mitchell, Smith, 2013, pg. 446). • From the aorta, the red blood cell travels into one of the arteries from the arterioles then will hit the capillaries (Marieb, Mitchell, Smith, 2013, pg. 446). • Within the capillary, the oxygen molecule that is taken by the red…
