Essays on Circulatory

The human body and the way in which it operates is a wonder in itself, but there are many more wondrous systems which keep this body going in the way that it does. One such system is the circulatory system which is exclusively responsible for the distribution of blood towards all of the organs scattered within the body. There are many organs and a scattered network of blood vessels which all come together to get this system up and running, and any hitch in any one of these individual blood carriers could become tedious and sometimes even chronic for ...

Cardiovascular system

The cardiovascular system is also known as the circulatory system, and it is the body’s transportation system that comprises the heart, blood vessels, and blood. The system does the work of transporting oxygen, hormones, cellular waste products and nutrients to all the parts of the body. The use of blood transports all the products, and it is approximated that the body of an adult makes use of five liters of blood to transport the products from one part to the other. Blood is pumped from the heart through the arteries then gets into body tissues through capillaries (Inner ...

Definition of Community-Identification and History

Jersey City is in the Hudson County of New Jersey State and it part of the New York metropolitan. It is the largest and the capital the City of Hudson County, and the second largest city in New Jersey. The history of the city runs back to the 17th century when it was inhabited by the Lenape people, an East Asian community that migrated to the Unites States. Jersey City acts as a transit center for manufacturing companies in New York due to the availability of the waterfront, and the population is highly mixed as a result of a ...

Q1. Prevention of Errors and Patient Management

Blood products are considered medications and thus should require the same level of precautionary measures as when a nurse administers a drug to a patient. Errors in blood product administration can be prevented by learning and adhering to applicable guidelines. According to the Australian and New Zealand Society of Blood Transfusion (ANZSBT, 2011), a checking procedure should be undertaken for blood products prior to transfusion. The nurse must check that the blood group as indicated on the product is compatible with the patient’s blood group as indicated on the laboratory compatibility label (ANZSBT, 2011). In case there are ...

Abstract

The literature defines hypertension as a medical condition experienced when the systolic blood pressure (BP) is equal or greater than 140 mm Hg or when the diastolic blood pressure is equal or greater than 90 mm Hg. Additionally, it offers a description of systematic, cellular, as well as molecular causes of hypertension. High blood pressure within the arteries is referred to as systemic hypertension (SH). The primary role of the systemic arteries is the transportation of oxygenated blood from the heart to the tissues of the body. The constriction of the arterioles (small arteries) is responsible for the high ...

Absorption

Absorption is the process through which biomolecules traverse through the GI tract into the circulatory system. Digested food gets absorbed in the small intestinal lumen through four processes, which include active transport, passive transport, endocytosis and facilitative diffusion. The efficiency of absorption of nutrients may be attributed to the large surface area lined up with hair like projections and microvilli cells .

Excretory System

Excretion is the mechanism through which waste products and eliminated from the body and osmotic pressure and homeostasis is achieved in the body . The process of excretion in the body takes place in three stages: filtration, reabsorption and ...

Lab Report for Circulatory system

Introduction & background information:- The circulatory system is a large interconnected network of organs and vessels which causes the flow of blood, nutrients, oxygen, hormones and various gasses between the cells of the body. If the circulatory system were absent in the human body, it would not be able to defend itself against diseases and illness or to maintain a constant internal environment, for example, the correct temperature or the pH. This process is called homeostasis. Hence, it can be said the circulatory system consists of the heart and the lungs which work in unison for the transportation of blood ...

Introduction

Air pollution involves the introduction of particulates and other biological molecules in the atmosphere, resulting in the death of humans, other living things and damage to other resources such as crops. It involves the interaction of different pollutants which eventually affect the environment, health, and even the climate. These pollutants are emitted almost from all economic and social activities. The most cases of air pollutants are; Sulphur Dioxide, Nitrogen Oxides, Particulate Matter, Ozone, Ammonia, Non-methane volatile organic compounds, carbon dioxide, lead, heterocyclic, chlorinated hydrocarbons, phenol and Methane amongst others. Emission of many air pollutants has decreased across Europe as ...

Nature in city; seed bank; ecosystem and social-urban development.

The terms “ecology” and environment” have different conceptual meanings which often overlap with the concept of “nature” in the context of academic and scientific research and analysis. For instance, ‘Natures and Ecologies’ studies explore the environmental dimensions of ecosystems which includes both physical parameters and biotic attributes of a particular region. The “environment "includes the physical world, the social world of human relations and the built world of human creation. [Ankers 2005] Within the various uses of the word today, "nature" often refers to geology and wildlife. Nature can refer to the general realm of living plants and animals, ...

Healthy behaviors play a key role in daily life. Yet, certain unhygienic practices tend to interfere with the health and induce a risk to the overall life. These practices could be high-fat diet, alcohol, and smoking. There is a need to know much about these. In such context, the present description deals with a topic “ What will kill you first, a smoking, a high-fat diet or alcohol?”.

Health -related risk factors:

A risk factor is any quality, trademark or presentation of a person that improves the probability of building up an ailment or damage. A few illustrations of the more vital danger elements ...

The cardiovascular and respiratory systems are largely responsible for the transportation of oxygen and carbon dioxide through the body. Respiration consists of both inspiration and expiration. These actions are the methods by which essential oxygen is exchanged with harmful carbon dioxide. While oxygen is brought into the lungs during inhalation to be processed throughout the body, carbon dioxide is brought during exhalation to be removed from the system entirely. Once the oxygen has reached the lungs it is taken up by the bloodstream in order to be distributed to the various cells that require a constant exchange of nutrients ...

What is organ donation?

Organ donation is the voluntary giving of an organ or tissue so as to help someone who needs them or whose organs have failed. Organ donation is normally done to save or enhance other people’s lives. Donating one’s organ is an act of generosity and any willing donor will be informed about the procedure and will be thanked for their actions to save humanity.

History of organ donation

Organ transplant experiments on humans and animals can be traced back to the 18th century. Scientists tried to transplant body organs on both animals and humans, but the experiments failed terribly. But not ...

What explains the decline in mortality in developed countries? Are there lessons to be learned in relation to the poor in developing countries today? I. Introduction

A. General Information

In general, the mortality level is deservedly considered to be among one of the characteristics that reveals both economic and social health of the certain state and that clearly describes the effectiveness of the policies that governments get used to adopt. In this context, the most significant particular demographic indicators are commonly the following: 1) Infant mortality rate; 2) Maternal mortality rate; 3) Mortality amid able-bodied citizens; 4) Mortality caused by external factors; ...
