Flow of Blood through the Heart

General Purpose:
Specific Purpose: To inform my audience about the process by which blood flows through the human heart
Thesis Statement: Why the heart is important, learning about its general anatomy. What happens during a single cycle of heart contraction, and how blood flows through the different chambers of the heart.

Introduction

Attention Getter: Do you know that the human heart never stops beating. And the over the course of a lifetime it can beat upt0 2.5 billion times, non-stop! On an average day, the heart pumps 2,000 gallons of blood through 60,000 miles of blood vessels.

The Role of Cardiovascular System

The cardiovascular system is responsible for the transport of oxygen and nutrients to the body. It is also responsible for carrying the waste that is to be eliminated by different organs (Shah et al. 2009, p. 11). This biological system is consisted of a series of tubes called the blood vessels that are connected to the heart which pumps blood. The arteries are the blood vessels that transport blood from the heart to the other parts of the body while the veins bring back the blood to the heart (Silverthorn 2007, p. 463-464). The heart is the main organ Continue reading...

The Kansas City Hyatt Regency Walkways Collapse occurred on July 17, 1981 (Edward 1). This coincided with the tea party that was organized by the hotel in their atrium lobby. With many guests being invited, most of the party goers were dancing with others standing at the suspended walkways. As a result of this, the ceilings rods that supported the walkways in both the second floor and the fourth floor around the atrium became weak and overwhelmed. It therefore led to the collapse of the walkways onto the first-floor atrium which was very crowded (Edward 3). However, the third-floor Continue reading...

Atrioventricular Septal congenital heart defects (ASD) are caused by a hole that is found in the septum wall that separates both sides of the heart chamber. The hole causes blood to flow improperly from the left atrium to the right atrium instead of into the left ventricle. (Thompson).
Symptoms of ASDs are dependent upon the size of the hole. If the hole is small there will typically be no symptoms in early childhood and small holes often will close on their own as the child grows. If the hole is medium to large in size, it can produce symptoms Continue reading...

Congenital heart defects are problems intrinsic to the heart that present at birth. They develop during fetal growth in utero mainly due to genetic malformations, environmental factors, and multifactorial reasons. The environment within which the fetus develops (the uterus) is a very crucial contribution to normal fetal growth and development. It is common to find disruptions within this microenvironment; the consequent effect being the disruption of normal growth and organ developments. The timing is, however, important as well. During the first trimester, organs are being crafted from primitive cells and tissues. Internal and external factors, therefore, take the opportunity Continue reading...

Introduction

This paper will describe atrial fibrillation, its causes, diagnosis, and treatment. The paper will also focus on the clinical representation of the condition, the various types of it, and a conclusion part for the discussion.
Atrial fibrillation is a term used to refer to a condition of the heart that causes the rhythm of the heart to be abnormal (Patel, et. al., 2011). The heart is made up of four chambers, each with muscles that help pump the blood throughout the body in a regular co-ordinated rhythm, referred to as normal sinus rhythm. For the heart to perform its Continue reading...
