Chemical engineering treats circularly system as a chemical process that involves the heart as a pump while the blood vessels act as passageways for oxygen. Generally, chemical engineering uses mathematical equation to show a complete oxygen transportation process in the body. Moreover, chemical engineering involves two basic terms including convection and diffusion that helps in calculating oxygen transport in the human body. Convection is more common in the large blood vessels like arteries while diffusion is more likely to occur in the small blood vessels such as capillaries and veins.
The two main mathematical equations involved in determining oxygen transport are the overall flux that describes oxygen flow via pipes and Fick’s law that explains diffusion of fluid along a concentration gradient.
Oxygen moves in the human body in the breathing process through nose and mouth then goes via the lungs and dissolves in the water lining of alveoli. Oxygen then sticks to red blood cells while passing through the alveoli capillaries.
Circulatory system plays a significant role in transporting various materials in the human body. Circulatory system ensures that nutrients, water and oxygen are transported to the body cells while transporting waste products produced by body cells such as carbon dioxide away from the body. The circulatory system acts as a highway with network throughout the human body and it involves the heart, and the blood vessel. The heart is responsible in pumping blood and maintaining blood flow in the whole of the body system while the blood vessels transport blood away from the heart to other parts of the blood. The whole of the circulatory system transports oxygen from outside the body into the blood stream and carries away waste from the blood cell, carbon dioxide to the outer part of the body.

The paper also deals with history or origin of human rights. The purpose of human rights is to ensure peaceful and orderly social and political functioning within a state. To safeguard interests of its citizens, several national and international bodies are formed.
The global recognition of human rights started with the Universal Declaration of Human rights in 1948. Over the years, numerous regional and international treaties have been signed and ratified by different countries in order to protect the universal human rights of the citizens.
Unfortunately, these people again became a victim of two British Pirate ships who attacked the ship and won the battle. (Fareell, C. Pg 9 2011) And the story of human trafficking started with the concept of slavery; it’s actually a modern form of slavery where people involved in this business makes money by controlling and exploiting others.
in managing the company’s financial status rather than focusing on costs alone, improve management processes, tools, and managers so that current workforce produces more output at a higher quality. Hence the goal of the changes in compensation program is reducing the labor
674-675). While talking about the telecommunication organizations, O2 is one of the growing telecommunication brands in the region of UK that provide internet, telecommunication, and financial services for the residents of UK. Moreover, the ranking system authenticates the prominence of O2, as it comes under counting amongst the top brands of UK (Ferrell and Hartline, 2010, pp.
The author states that cloning is discouraged by various nations as cloning is against the rule of nature, which is generating humans, nurturing them and paving the way for uncertainties related with the repercussions of science. At present human population has crossed the figure of 7 billion, a huge burden on the planet.
As a result of this, the challenges for human resources managers have increased manifolds. Women make a significant portion of the workforce in the present age. A considerable amount of challenges occur because of the issues of the women. Of the whole range of issues of women that they experience at the workplace, some of the issues that have been discussed in this paper include the need to strike a balance between the work and family, pregnancy, pay equity, discrimination, and glass ceiling.
The United Nations, for example, adopted the Trafficking Protocol in the year 2000 in Italy, which is a component of the Palermo protocols named after Palermo, which is the location in Italy where they were adopted.
