The Development of Ground and Air Transport - A. The development of ground transport In old days, before the wheel invention (pre-3000 B.C) people normally were carried the sick and wounded on the shoulder between two men or backs of friends or animals(MacDonald & Miller, 1989). Forced transports were used for those with mental disorders in ancient time, however, one of the earliest uses of the wheel for patient transportation was constructed (circa 900 A.D.) by Anglo-Saxon, so they called it the Anglo-Saxon wagon hammock(Bell, 2009). This hammock was placed between two poles raised on a four wheeled platform(MacDonald & Miller, 1989)....   [tags: Transportation ]

Vesicle Traffic and Cellular Transport - The process of cellular transport is a concept we have all learned during our high school biology classes. In a eukaryotic cell, there are two types of cellular transport. Passive transport does not utilize ATP, or adenosine triphosphate, to move molecules or waste. Instead, it uses the process of diffusion, in which substances move between the plasma membrane of the cell from high concentration of the substance to low concentration. The substances that are usually moved are small, uncharged molecules, such as carbon dioxide....   [tags: exocytosis, endocytosis, Rothman, Sheckman]

Aviation Transport and Road Travel - ... If a plane crashes into the ground nose first, then the plane will be destroyed almost immediately. But if the plane hit the ground wing first, it will explode on impact because there are fuel tanks inside the wings. There are so many safety features in planes today that it is almost impossible for a plane to crash. There are many possible causes for plane crashes, for example, pilot incapacitation, pilot error, hijacking, lightning, fuel starvation, faults in the design, detonation of a bomb, and electrical/hydraulic failure....   [tags: car accidents, airplane]

Transport in Mammals - Transport in Mammals A recurring theme in biological systems is the surface area to volume ratio. All cells require nutrients and most require oxygen as well. Wastes also need to be removed. With a small organism this demand can be met by simple diffusion over the body surface but larger or very active organisms need a transport system with a pump to ensure that the supply meets the demand of all cells, even those deep within the body. In mammals, the pump is the heart. Substances are carried in a transport medium of the blood....   [tags: Papers] 2426 words

Exchange and Transport in Protozoa - Exchange and Transport in Protozoa The exchange of gases between the environment and cells occurs via the process of diffusion. Diffusion depends on: · The amount of surface area available for diffusion. The larger the surface area the greater the rate of diffusion. · The concentration gradient. An organism which respires very quickly will have a much lower concentration of oxygen in the cells and a higher than normal concentration of Carbon Dioxide. So the greater the concentration gradient across the respiratory surface the quicker the rate of diffusion....   [tags: Biology] 429 words

The transport of water is simple the cell being selectively permeable will allow water through it until an equilibrium is reached and at that time water will flow both in and out of the cell maintaining the equilibrium. For example a red blood cell is placed into a isotonic solution which means both the solution and the cell have the same concentration the net movement of water is zero, water however does move freely in and out of the cell to maintain the balance....   [tags: essays research papers] 537 words
