Download file to see previous pages The amazing function of the heart is to pump blood though these 60,000 miles; blood which carries essential nutrients, hormones and oxygen to some 3 trillion cells of the body. The exchange of nutrients and wastes between blood and the cells occur at the capillaries. The human cardiovascular system is a closed system, which gets narrower as the vessels reach the cells and finally widens as the vessels reach the heart. Such a system allows a large surface area for exchange of nutrients and gases at the cell-capillary interface. Blood circulation is so important for the body that if the heart stops beating even for a few minutes, it can be fatal. The heart beats for an average 100,000 times a day pumping about 2000 gallons of blood per day throughout the body. It pumps the entire blood volume of an adult body of 5.6 liters for three times in a minute. Anatomically, heart is made up of cardiac muscles and consists of four chambers, separated by valves. The blood vessels are made up elastin membranes and smooth muscle cells (Clemente, 1985). The lymph node is the main functional unit of the lymphatic system. Here the immune system is primed and most of the immune cells are activated to fight the foreign substances in the body. The rudimentary heart is a pair of tubular vessels, the primitive aortae, and develops in the space of the pericardial area. These then develop a direct connection with the vessels of the yolk sac. Each vessel receives a vein called vitelline vein from the yolk sac, and prolong to form the dorsal aorta. A branch of the dorsal aorta forms the umbilical artery. Later the primitive aorta develops a ventral and a dorsal part connected by an arch. The two primitive aortae then fuse together to form a single tubular heart, whose posterior end receives two vitelline veins. The tubular heart beats rhythmically and pumps blood to the developing embryo. This is called vitelline circulation. There is a mesodermal tissue between the endothelial lining and outer wall of the heart, from which musculi papillares, chordae tendineae, and trabeculae later develop. The simple tubular heart later elongates and bends upon itself and forms an ‘S’ shaped structure. In due time constrictions in this structure divides it into five structures including primitive atrium and primitive ventricle. Constriction between the atrium and ventricle forms the atrial canal and form the site for atrioventricular valves. The sinus venosus forms behind the atrium whose right horn and transverse portion later form a part of the adult right atrium. The atrial canal forms into endocardial cushions and the septum intermedium, which forms the future right and left atrioventricular orifices (Clemente, 1985). Figure 1. Structure of human heart, and blood vessels. Sources: 1. 2. The heart and the great vessels are contained in a conical fibro-serous sac, between the lungs. The heart is a hollow and muscular organ. It measures 12 cm in length and 8-9 cm in width, and weighs around 280 grams. It is divided into four chambers, the upper two are called left and right atrium, while the bottom two are called left and right ventricle. The atria are separated from ventricles by the coronary sulcus and the interatrial groove separates the two atria. Anterior longitudinal sulcus and the posterior longitudina ...Download file to see next pagesRead More

Budgetary Control and Costing System

Job costing and Process Costing are the two basic methods of costing. Job costing is suitable to industries, which manufacture or execute the work according to the specifications of the customers. Process costing is suitable to industries where production is continuous and the units produced are identical. All other methods are combinations, extensions or improvements of these basic methods.

1. JOB COSTING: It is also called specific order costing. It is adopted by industries where there is no standard product and each job or work order is different from the others. The job is done strictly according to the specifications given by the customers and usually, the job takes only a short time for completion. The purpose of...

Effective Methods of Teaching Anatomy

Herein, comparisons will be made to highlight the differences in using anatomical models for study versus self-directed (usually textbook) learning. As well, the use of tutors as an advantage in the medical classroom will be discussed.

Some students are hands-on learners. For them, three-dimensional (3D) anatomical models are effective. “Exploratory tools enable users to investigate structures in ways not possible in the real world” (Implementing, para. 3). These 3D models can represent just about any part of the human body. Models are available of small structures, like the head, or of the entire human skeleton. Models of the entire human body can also be purchased. Some of them even have removable parts so...

Comparison of the Cold War International System to the Current International System

An example is that of the Korean War (1950-53) which is said to transform the nature of the Cold War, while its initial impact was to solidify the division of the world into political, military, and economic spheres. Take Germany for instance where imperialism was a victim challenged by the historians for the destruction of the German Government along with its supporters used to conduct (Keylor, 2001, p. 44). That indicates economic expansion and territorial acquisition has always been a problem promoted since the First World War. Even in the 1920s, it was fashionable to declare the German empire on the threshold of the ‘Great War’ (Keylor, 2001, p. 44).

Europe in the global context remained tense and divide...

Billing System Upgrade with Web-Based Version Project of Rick Auto Enterprises: A Communication Plan

The project is envisioned to involve changes to existing business processes, changes to existing jobs, and/or the creation of new positions. With the new web-based version, customers and auto brokers will be able to view and pay their bills online, as well as access a billing customer service agent is required. This change will affect the billing, sales, and customer service departments but it is expected to reduce costs, improve customer satisfaction, and reduce the number of days for outstanding accounts receivable.
Ownership of the existing system rests with the Billing Department. However, with the benefits projected to be derived from the upgraded system, especially with the implantation of the web-based version, the Cus...

Normal Anatomy and Causes of Knee Arthritis

A complete loss of articular cartilage is noted resulting in soft, elasticity loss, and fibrillation of the articular cartilage leading to the burned bone that is devoid of cartilage (Schwartz et al. 1942; LeadingMD par. 2). Complete loss of articular cartilage results in narrowing of the joint space, bone spurs, motion loss, pain, and disability (Schwartz, et al. 1942; LeadingMD par. 2). Knee arthritis, that typically influences patients over 50 years old, affects all knee cartilage leading to biomechanical and biochemical changes that impairs cartilage function (LeadingMD par. 6).

Knee arthritis occurs as a consequence of an injury, surgical procedure that includes partial or complete removal of the meniscus cartilage...

Microprocessor System and Application

In a computer, a processor commonly involves one or more microprocessors (also acknowledged as chips), which are silvers of silicon or other substance stamped with many little electronic circuits. To perform operations on data, the computer passes electricity all the way through circuits to execute an instruction (Norton 2001.p. 5). The innovation in technology has brought a lot of facilities for us. We have better ways of life and all the facilities regarding better production and domestic tasks. Such as in the industrial production we have automatic robots that are welding, packing, moving and carrying out several other development-related tasks. These robots are pre-programmed and microprocessors based chips are controlling all...

The Interprofessional Practice and the Health Care System

This is also the position Stone (2007) takes in the quote under discussion.
Furthermore, Stone goes on to declare that Australia has been very slow to implement this practice as compared with other countries and government agencies. One of the primary reasons is that the public policy system in Australia is quite complex and the decision-makers have not come into agreement on where to place it in the policy matrix. This leaves Interprofessional Practice and Education in the dark (or the cold) as far as strategic planning for implementation as well as placing itself within the funding cycles of the government disbursements. (Stone, 2007)
Policies are created in order to put in place how politicians and government official...

Identification of problems in the Criminal Justice System of the US

They are on trial and will be dealt with fairly. These laws ensure that no one, even if he or she has committed a crime is abused or punished cruelly.
Following the history of civilization like in china, we see the traces of systems for Criminal justice in order to provide safety for the citizens. Evolving through the years laws have been modified and changed to form the system that we know today.
 From its start, the “U.S. criminal justice system” has advocated the idea of “checks and balances”. To avoid dictatorial rule, the people who founded this system in such a way that one person was not given control or authority completely to punish the criminals. The idea of assigning a ‘jury...

Comparative Review of Welfare System

In order to compare the welfare system of the three proposed countries, it is important to first develop a comparative method that would guide in comparing the three states. For the purpose of this paper, a binary comparison would be conducted. The implicit comparison would deal with Britain while the explicit comparison would explore the USA and Canada. Thereby a small N’ study would be used, that is, of three countries.
The three countries selected to share a similarity in the form that these countries are a welfare state. This is when welfare is mainly funded by the state. While the USA and Canada focus on the liberal welfare state, the welfare state of the UK is not quite defined.
The comparison of the welfare...
