  • Pacemaker And Icd Similarities

    pacemaker the main similarity is that they both are pacemakers that send impulses to stimulate contraction of the ventricles, each have a generator with leads connecting it the ventricles. The main difference between the cardiac pacemaker and the CRT is that there are two leads to the ventricles, one to the left and one on the right, which restores the 4,6,7contraction of the left and right ventricle at the same time. This allows an even flow of blood through both chambers with better cardiac…

  • Frog Integumentary System

    The subphylum Vertebrata includes all the familiar animals we tend to see everyday, and some rare and unusual ones (O’Neil, 2012). Scientists classify the seven different Vertebrates based on their skeletal system, general environmental adaptation, and reproductive systems. These seven Vertebrates include, Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia. During the lab dissection, the class dissected organism from only four of these classes. First, we dissected the…

  • Vertebrates Circulatory System

    The pulmonary circuit transports blood from the right ventricle to the pulmonary trunk to the lungs to the left atrium. This oxygenates the blood. The systemic circuit transports blood from the left ventricle through the aorta to the body’s tissues. Coronary arteries are used by the heart to collect oxygen-poor blood from the capillaries and deposit it into the right atrium. Toxins…

  • Systolic Dysfunction Research Paper

    systolic function is measured and assessed. This will also include any formulas used to determine needed volumes and percentages. Lastly I will cover three causes of systolic dysfunction. Systolic function in its simplest terms is, how well the ventricle contracts. However,…

  • Fontan Procedure: A Case Study

    In 1971 Dr. Fontan and Dr. Baudet [26] did the first total cavopulmonary connection ‘‘Fontan Procedure’’ which is the final palliative stage for single ventricle patients. Since then, multiple techniques and modifications were invented. However, the ultimate goal of all different procedures is to achieve near complete separation of pulmonary venous return from systemic venous return. As such, all systemic venous circulation will be directed to the Fontan circulation (except the coronary sinus…

  • Cardiac Cycle Research Paper

    hearts through the superior vena cava 9 and the inferior vena cava 10, this blood enters the right atrium 11. Now the right atrium contracts pushing the blood into the right ventricle 1 through the tricuspid valve. As the ventricle is filled the tricuspid valve closes to prevent any back flow of the blood. The right ventricle contracts forcing the blood to enter into the pulmonary artery 2 through the pulmonary valve. The pulmonary artery extends into both of the lungs where the deoxygenated…

  • Dissection Summary

    chambers. 1. Right atrium 2. Left atrium 3. Right ventricle 4. Left ventricle The atria are a lot smaller than the ventricles. The walls of the atria are a lot thinner and a lot less muscular than the ventricles. The atria are there to act as receiving chambers for blood. They are connected to the veins which takes the blood to the heart. The ventricles are much larger they are also much stronger to be able to pump blood out of the heart. The ventricles are connected to the arteries that…

  • The Circulatory System

    and the systemic circuit. The pulmonary circuit is simply the movement of blood from the heart, to the lungs, and back up to the heart again. Deoxygenated blood leaves the right ventricle of the heart and runs through the pulmonary artery; from here, the blood is pumped through the right atrium and into the right ventricle. The blood continues its course and travels through the lungs. While in the lungs, the deoxygenated blood releases its carbon dioxide and picks up oxygen through the process…

  • Differences In Feetal Circulation Vs. Postnatal Circulation

    tricuspid valve, right ventricle, pulmonary semi lunar valve, pulmonary arteries, lungs, pulmonary veins, left atrium, bicuspid valve, left ventricle, aortic semilunar valve, aorta, systemic circulation, vena cava. Fetal circulation works by using three shunts to direct deoxygenated blood and avoid the not yet fully developed lungs and liver. The patent foramen ovale…

  • 78 Organs In The Human Body

    remains, “how does it do it?” To understand that, we first need to know a little about the structure of the heart, the heart has four chambers or “rooms”. The atria, are the two upper chambers that collect blood as it flows into the heart, and the ventricles are the two lower chambers that pump blood out of the heart to the lungs or other parts of the body. It has four valves, the tricuspid valves is in the right side of the heart, between the right atrium and the…
