Respiration & Circulation - Lab Report Example There are different parts of circulation and respiration. They include heart, blood vessels, capillaries, blood, spleen, trachea, lungs, and pericardium (Starr and McMillan 2013). Respiration involves inhalation and exhalation of air. The respiratory system is a structure that enables human beings to breath. As stated earlier, respiration involves absorption of oxygen from the atmosphere and elimination of Carbon dioxide. The respiratory system is identified by different structures from the nose to the chest. Some of the structures are the nose, throat, larynx, trachea, primary bronchi, and alveolar duct. The structures of respiration are categorised into lower and the upper respiratory tract. The nose, mouth and the trachea form the upper part, which allows air in and out from the body. The lower parts of the system include trachea, bronchi, broncheoli, pulmonary alveoli and lungs. The trachea is in the two parts of the respiratory system. However, the upper part of the trachea is a small section while lower connects the bronchi and the throat (Jakab 2007). Each lung has  of roughly  300 million alveoli, which  are in the form of tiny sacks formed at the end of the bronchioles. Tiny blood vessels surround alveoli. Alveoli form a large surface that makes it good for gaseous exchange because the tiny layer of the blood vessels covers the alveoli. Oxygen from the alveoli enters the blood vessels while the CO2 is eliminated from the blood vessels. This is because the blood vessels surrounding the alveoli have more CO2 than the alveoli that have more oxygen. For a balance of both gases, oxygen diffuses to the blood while CO2 diffuses out from the blood to the alveoli. CO2 is breathed out while oxygen breathed in hence gaseous exchange takes place (Fosbery and McLean 1996). During inhalation and exhalation, the pressure and volume of the lungs change. When air is breathed in, the ribs move upwards

Issues in eDUCATION - Essay Example In order to provide a good quality education to students, teachers should develop new teaching and learning strategies that could increase the students’ motivation in learning. By doing so, school teachers will be able to convert the students’ negative learning attitude into a positive attitude and behaviour. (Schweinle et al., 2006) For the purpose of this study, the researcher will discuss the factors that could increase the students’ misbehaviour inside the classroom including: (1) the size of the classroom; (2) differences in learning capabilities of each student within an inclusive classroom; (3) Medical or Genetic Factors; (4) school teachers’ inability to develop an outstanding classroom environment that could increase the students’ curiosity in learning; and (5) other factors: boredom in class or frustration in learning. Knowing these factors will enable the readers to have a better idea on how to control the students’ misbehaviour in class. As part of controlling the students’ misbehaviour, the researcher will first examine the difference between disciplinary actions using the managerial and educational activity prior to concluding which among the two methods are more effective in managing a class. Among the five possible factors that could increase the student’s misbehaviour inside the classroom including: (1) classroom size; (2) differences in learning capabilities of each student within an inclusive classroom; (3) medical or genetic factors; (4) school teachers’ failure to develop an outstanding classroom environment that could increase the students’ curiosity in learning; and (5) other factors that could cause boredom in class or frustration in learning; the most important factor that school teachers should artistically learn to control within an inclusive classroom is the medical and genetic factors. This is primarily because other factors could
