Create a 9 pages page paper that discusses human physiology and anatomy. The respiratory system includes various processes which eventually allow the delivery of much needed oxygen into the cells of the body. This paper will explain how the structure of the respiratory system facilitates ventilation and gas exchange. It will also describe the primary factors affecting gas diffusion through the respiratory membrane. it shall also discuss two pathological conditions (emphysema and pneumonia) which reduce diffusion rate. This essay will also distinguish between restrictive and obstructive respiratory diseases and outline how they are diagnosed.

The respiratory system is a system consisting of various organs and tissues which have specific roles to play in the breathing process. The primary organs which facilitate the exchange of gases include the bronchial airways, the lungs, and blood vessels, as well as various accessory muscles used for breathing (Tieck, 2011). The airways are bronchial tubes where the air from the atmosphere passes on its way to the lungs. these same tubes also bring carbon dioxide out of the lungs (Tieck, 2011). The airways would start with nostrils followed by its associated air passages or cavities: the mouth, the larynx, bronchial tubes and its smaller branches. Air would first enter the body through the nose or the mouth and then goes through the trachea, into bronchial tubes and then to the lungs (Tieck, 2011). The nose contains hairs which partially filter the air from dust particles and other foreign particles. From the nose, the air flows further into the nasal cavity. The nasal cavity has epithelial tissue and blood vessels which basically moisten and warm the air entering its pathways (Tieck, 2011). Mucus is also secreted in the nasal cavity and helps clean the air from any contaminants.
