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

Circulatory system is one of the body systems. In association with other body systems, it supplies oxygen and nutrients to the entire body (Bjorklund, 5). The system is made up of three main parts namely the heart, blood vessels, and blood (Bjorklund, 5; Vijayalakshmi, Rao, and Reema, 839). The heart pumps blood to the lungs and throughout the body through a complex network of blood vessels. On the other hand, blood carries oxygen, nutrient, and wastes to different parts of the body.
Heart rate is the number of times one’s heart beats per minute. In the experiment, my Continue reading...

Abstract

This study explores the differences in metabolic requirements in walking and bicycle riding by comparing the heart rates of both exercises. The heart rates reflect the metabolic requirements of both exercises. The hypothesis of this study states that the heart rate (in pulse per minute) of walking is significantly lower than the bicycle riding. Heart rates were measured as pulse per minute (ppm) from a sample of college students in resting (462 samples), walking (464 samples) and bicycle riding (439 samples) exercises. The average heart rates were compared and the t-values were calculated to statistically justify the differences. The Continue reading...

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...

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.
Did 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...

Heart muscles require oxygen-rich blood for its nourishment. and coronary arteries in our body provide the oxygen-rich blood to the heart. Sometimes due to formation of plaques of different sizes as a result of deposition of fatty matter, calcium, protein, and inflammatory cells within the arteries, the coronary arteries become narrow and blood cannot flow normally. When such plaques restrict the flow of blood within the artery the heart muscles cannot get the required oxygen through the blood, if the blood flow is not restored quickly the section of the heart muscles begins to die in want of oxygen. ( Continue reading...

Abstract

The different cells of the higher animals create specialized organs, tissues, and systems that have particular functions. For example, the tissue organizations that constitute the respiratory system promote breathing and, hence, allow the exchange of gases. The cardiovascular arrangement employs the blood to transport the gases, as well as other substances in the body. Additionally, the respiratory and cardiovascular systems have a close integration, such that a response to a body change in one system is manifested in the second system. The present study, therefore, investigated the cardiovascular physiology, as well as the integration of the respiratory and the Continue reading...

ABSTRACT

Cardiomyopathy is a heart disease characterized by stiffening and hypertrophy of the musculature of the heart followed by scarring. It deprives the heart from the flexibility required in the muscles to pump the blood sufficiently leading to heart failure. There are four major types of cardiomyopathy and it can be acquired or congenital. Latter usually unpreventable and can only be controlled. Usual symptoms are shortness of breath, easy fatigability, edema of limbs and venous engorgement. Clinical as well as radiological evidence is required for its diagnosis. Surgical interventions are available to treat cardiomyopathy and besides pharmacotherapy, physical activity and Continue reading...

A preliminary evaluation of the medical history of the patient presented in the case study curtails the possibility of disease present to congestive heart disease. Symptoms such as shortness of breath or dyspnea, fatigue, and urinary incontinence are some of the common manifestations of congestive heart failure plus its complications. Ruling congestive heart disease in as the main culprit in the patient’s condition, the shortness of breath she experiences may be attributed to the possible pulmonary edema or water retention in the lungs which obstructs normal respiration and causes difficulty and shortness in breathing (Gillespie, 2006). Aside from Continue reading...
