Erasistratus’s model of the respiration and blood distribution is considerably more mechanical than Aristotle’s due to the technological advances that were thriving in Alexandria compared to Athens. Both scientists base their models of respiration and blood distribution in the body from technological-ladenness of observation. Erasistratus proposes that heart uses force propulsion to distribute air and blood throughout the arteries and veins. His concept focuses on “the filling towards what is being”

The effect of education on the development of different countries As the increasing demand for skilled workers‚ more attention has been paid to education. Education has been developing follow the step of humanity which affects knowledge‚ skills and attitude from one generation to the other (Compayre and Payne‚1899) and interacts on the progress of civilization. The impact of the rapid growth of education is felt at institutional‚ national and international levels‚ and these are inter-related.

define aging as time dependent or age progressive reduction in intrinsic physiological function leading to a high specific mortality rate and a decrease in specific reproductive rate. Cellular aging therefore‚ can be described as an increased susceptibility to cell death caused by the loss of cellular functions such as cell division‚ cell communication‚ transport and delivery. A cell ages gradually until it gets to the senescence stage which is a process by which a

What is Life? This perennial question the answer to which has somehow eluded the most brilliant minds. For while scientists have identified many years ago the right mix of the atoms and molecules that constitute cellular material‚ they have not succeeded in ‘switching it on’ to make it alive‚ or ‘breathing life’ into it (Rabago et.al‚2006) In this module you will: a. Explain the concepts of the cell theory b. Identify the parts of a cell c. Describe the function of each cell part d. Differentiate

transport oxygen rich blood from the alveoli back to the heart. Inspiration (the process of inhaling) begins as the external intercostals and diaphragm contract. When this happens‚ the lungs expand. After this‚ negative pressure is used to facilitate respiration. So‚ air moves from an area of higher pressure‚ which is the air‚ to an area of lower pressure in the lungs and aveoli. During inspiration the diaphragm and intercostal muscles contract. The diaphragm moves downwards‚ while the intercostal muscles
