Respiration & Circulation - Lab Report ExampleThere are different parts of circulation and respiration. They accommodate heart, line of products 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 identify 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, m pop outh 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 t he 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 hasof roughly300 million alveoli, whichare in the form of tiny sacks formed at the dying of the bronchioles. Tiny blood vessels surround alveoli. Alveoli form a large surface that makes it good for gaseous alternate 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 ring 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 unvoiced out while oxygen surd 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
