  • Essay On Mittral Valve Prolapse

    imbalances of the autonomic nervous system. Many people who don’t have symptoms find out they have mitral valve prolapse during a general physical exam. When a doctor examines a patient with a stethoscope, a clicking sound is heard soon after the ventricle begins to contract. If there is associated leakage of blood through the abnormal valve opening a “whooshing” sound can be heard immediately following the clicking sound. This is a heart…

  • ECG Signal Essay

    generating an electrical impulse which travels to the left and right atria, causing them to contract. Following the start of atrial depolarization, the impulse quickly arrives at the atrioventricular node which is responsible for the contraction of ventricle. The SA node creates the electrical impulse which causes the heart to beat, but the Autonomic Nervous System controls the heart rate and the strength of heart contractions. The ANS consists of two parts, the Sympathetic Nervous System and…

  • Essay On Cardiomyopathy

    likely to occur in men than in women. It starts in the left ventricle, when the heart muscle begins to dilate and doesn’t contract normally. When this happens, it then may spread to the right ventricle and atria, causing the heart to become weak and fail. Hypertrophic cardiomyopathy is the second type and can affect people of any age. It occurs when the walls of the ventricles thicken. If thickening blocks blood flow out of the ventricle, it’s called obstructive hypertrophic cardiomyopathy and…

  • Ventral Vs Dorsal Difference

    Diagram the ventricular system. Be certain to include: the lateral ventricles, the 3rd and 4th ventricles, the cerebral aqueduct, and the central canal. Describe the purpose of the ventricular system. In your answer be certain to define components of this system that are more difficult the diagram; specifically Cerebral Spinal Fluid and Arachnoid granulations. (10 points) The ventricular system is made up of ventricles in the brain which contain CSF (Cerebrospinal fluid). The purpose of the…

  • The Closed Circulation System

    control the rich and poor oxygenated blood to mix. These are the right and left side that contains the four chambers; right atrium and right ventricle for right side and the left contains the left atrium and left ventricles. The upper part which are the left and right atrium are the one receiving the blood meanwhile the lower chambers, the left and right ventricle, are the one that pumps the blood our of our heart as the heart contracted. On the right atrium, there is a part called superior…

  • Circulatory System Lab Report

    lungs and the skin and enters the left atrium. This area is the primary gas exchange site in most amphibians. Both atria dump into the single ventricle. The ventricle is divided into two narrowly separated chambers, which reduces the mixing of the two types of bloods. When the ventricle contracts, it sends oxygenated blood to the brain from the left ventricle and then reaches the head through arteries. The skin and lungs receives pure blood from the right atrium. The skin and the lungs, oxygen…

  • Differences Between Cardiovascular Responses And Adaptions

    increase in exercise. The cardiovascular responses that should have occurred after 8 weeks of exercise, would include, an increase in size of the left ventricle, increase in stroke volume, increased cardiac output, increase in contractility, and an increase in blood flow to myocardium. The muscular walls of the heart thicken especially in the left ventricle, which leads to a more powerful contraction. The increased thickness of the walls of the heart also increases contractility, which causes an…
