  • Essay On Coronary Arteries

    closer to the apex, it will converge into the anterior interventricular arteries, which are a part of the left coronary arteries. These arteries mostly run across the underside of the heart, also supplying blood to the bottom portion of the left ventricle and the posterior portion of the septum. The coronary arteries anastomose many times which allows for many routes for blood delivery. Once the blood passes through the capillary beds of the myocardium, cardiac veins then collect the venous…

  • Circulatory System Essay

    The heart has 4 sections inside: left and right atria and left and right ventricle. The right atrium receives blood that is low on oxygen molecules from the superior and inferior vena cavae. The superior vena cava is one of the largest veins in the body that brings de-oxygenated blood from the lower part of the body to the right…

  • How To Write An Ekg Lab Report

    The Mechanics of the Heart An electrocardiogram, or EKG/ ECG, is a non-invasive test that measures the electrical activity of the heart and its electrical patterns. An electrical signal is sent through the heart to produce contractions that move the blood. This is what an EKG measures. In total that test may take from five to ten minutes and are ordered by a doctor to examine the heart more close. An EKG is done while the patient is lying down completely still (in order to reduce artifact or…

  • In Vitro

    continuous into the venous tank, indicating the pressure in the right ventricle. The fluid then continuous to flow into the right atrium and into the pulmonary artery to a dispensable tube of length 26 centimeters giving 26 mmHg pressure. This fluid overflow is directed into the left venous tank which, its pressure indicated the pressure of the left atrium. This fluid then completes its circulation by traveling into the left ventricle to initiate a second round of circulation. This system was…

  • Heart Rhythm Abnormalities

    previous beat, causing the heart to contract earlier than expected. This arrhythmia is a very common occurrence in all ages and usually is not serious. Supraventricular tachycardia, or paroxysmal SVT or PSVT: SVToccurs when any structure above the ventricle (usually the atria or the AV node) produces a regular, rapid electrical impulse resulting in a rapid heartbeat. Sick sinus syndrome: Irregular electrical impulses generated by the SA node cause a slower-than-normal heart rate (sometimes…

  • Central Nervous System: A Case Study

    1.1 Overview
 CSF definition It is a well-known fact that the brain lies within the skull and the spinal cord lies within the vertebral column. Between the soft neutral tissues and the bones that house them are three types of membranous coverings called meninges. Some of the space between these coverings is called subarachnoid space and filled with clear and colorless fluid (cerebrospinal fluid “CSF”). CSF circulates inside the central nervous system through the ventricular part of this system…

  • Single-Linear Epidemiology: A Case Study

    Sinoatrial (SA) Node and its function is to send electrical impulses that stimulate your heart to beat, and these impulses induce the atria to contract. As the atria contract, the impulse moves on to the Atrioventricular (AV) node which leads the ventricles to contract (A). A pacemaker becomes necessary when the heart suffers from arrhythmia, a condition of irregular heartbeats, and is unable to contract at a rate deemed sufficient to meet the metabolic needs of the patient. Bradycardia is a…

  • The Vascular System: The Cardiovascular System

    four chambers. The four chambers are the left atrium, the right atrium, left ventricle and the right ventricle. The left atrium is the collecting chamber. It collects oxygen and rich blood returning from the heart. The right atrium is also the collecting chamber for blood returning from the trip. The left ventricle is a part of the pumping chamber and it pumps blood through all body parts. Lastly, the right ventricle is also a part of the pumping chamber and it forces blood out of the…

  • Case Study: Assessing Heart And Neck Vessels

    abnormal chamber openings (Weber & Kelley, 2014). The heart has four chambers two atria, which are the upper chambers of the heart and two ventricles, which are the lower chambers of the heart. They are then further divided into left and right. Between the upper and lower chambers there are valves to prevent backflow of blood. Between the right atrium and right ventricle tricuspid valve and between…
