The Respiratory System Essay

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).
To explain normal functioning of the

Factors that contribute to homeostasis of the system occur throughout the entire day and night, without conscious thought. The respiratory system functions for life-sustaining activities and if the respiratory system’s tasks are interrupted for any reason for more than a couple of minutes, the body can seriously be damaged irreversibly. Damage to tissues can occur, followed by the failure of all body systems, and eventually leading to death. While the inhalation of oxygen and removal of carbon dioxide are the primary functions of the respiratory system, it has other important roles in the body. The respiratory system helps regulate the balance of acid and base in tissues, a process necessary for the normal functioning of cells within the respiratory system. It also helps protects the body against pathogens and against toxic substances drifting in the air when inhaled. The respiratory system also houses the cells that detect smell through chemoreceptors, and assists in the production of sounds. The respiratory and circulatory systems work with one another to deliver oxygen to cells and remove carbon dioxide in a bi-phase process called respiration otherwise known as breathing. The first phase of respiration begins with inspiration or inhalation. Inhalation brings
